I am a cabinet and trim installer and have used this saw alot you can't ask for much better than this saw. Powerfull easy to use cuts miters lying flat at 31.6 degree sets on both compound and miter cuts, gives you the perfect miter cut each time. No more having to bed your material, just lay it down flat and cut the marks. Cuts a good twelve inches and has a usefull hold down clamp. Again for the money you can't go wrong with this saw. The only thing I wish this saw had would be a double compound option but this unit only tilts left where some other models for a few dollars more tilt both ways, but really not a big deal to me.

I am very pleased with the limited use so far. I purchased a RIDID MS-UV utility vehicle to mount the saw on and the combination is superb for mobility. I am looking forward to installing engineered hardwood flooring and using the saw for the project.

in the new world of sliding compound miter saws, you can't beat bosch. Not Hitachi, or DeWalt, or Crapsman. The all perform well, this one included. I sort of wish I had waited for the one with a laser, but I have eyes just as good. great performer.

I believe this to be one of the best if not the best mitre saws on the market today. We use everyday in construction and it is great.

THe Bosch 3915 is a great addition to my power tool collection. I was impressed with it's ability to cut 2x8's and 10's as well as fine trim. The rails have little play and can give you very accurate angle cuts in both miter and bevel positions cut after cut.The only thing that could be improved is the dust bag chute. IT clogs very easily when cutting undried (framing) lumber.

THIS SAW IS THE BEST IM A CARPENTER AND I LOVE IT BEST THING SINCE SLICE BREAD. DEWALT MAKITA AND HITACHI CAN JUMP ON DEEZ, THEY HAVE NOTHING ON BOSCH

I recieved my order promptly and satisfied with its performance. The only problem I had was the missing work piece clamp. Amazon mads it nearly impossible for me to file a error report. I ended up giving up in fileing the report.

Ok, so before I purchased this I never did any miter cuts of quality, but this unit makes this weekend warrior look like a professional. Wainscoated a bathroom with 30 feet of wall run, with 6 inch v grooved board (4 ft tall, one board at a time. Mitered all coners....everyone came by and said it looked professional...AND IT DOES. Unit is worth every penny. I researched which unit to get and for my money, you need not spend anymore than what this one costs. I would give it 5 stars if it had a laser...but I would not spend another hundred dollars for a laser. Unit came out of the box right to spec. Although I checked for adjustments, none were needed. If you can find a better one for this price ... Buy it!

I purchased my Bosch saw last year. Since, I have used it to build a 450 foot cedar fence,dog ear 900 cedar boards,install 900 square feet of wood flooring, and install crown moulding in three rooms.

The short of it is: I love this saw! It is accurate, powerful, and versatile. The blade is nearly finish work quality (60T) but tough enough for rough framing.The miter detents are beyond the competetion's standard 45R or 45L. The work top is larger than most.

As with any tool, you will find characteristics that need improvement. The Bosch is no different. The motor is mounted to the side near the arbor. This gets in the way of the work clamp assessory. Bosch's next generation 10inch has it mounted on top. The bevel feature is a single direction.

If you are looking for a SCMS, this is the one. Best of all, the price is right.

... and for the record, I have never known a miter saw's dust collector to work well enough to write home about, regardless of manufacturer.

My friend bought this from Amazon and loved the saw...Only thing he complained about was Amazon charged him Shipping cost.. which used to be free.

I would recommend buying at local stores instead of Amazon as beauty of Buying from Amazon is Gone !!!.. they now charge a Shipping fee...

Checkout local stores and compare how much you will save before buying from Amazon.

It is a little under powered and collects sawdust everywhere within the unit. Other than that, it performs as expected.

Started on fire after 4 hours of use. I'm now looking up the local service center...... Should have got a Delta or Ridged.

I picked up a Delta 10" CMS some time ago...a nice saw but limited in capacity. I have longed for an SCMS and after doing extensive research it came down to the Makita or this saw. Amazon had a 3 day special on this saw (just think a third off the price with free shipping) and I could not pass that up.

The saw arrived in excellent condition.

PROS:
1) slide mechanism is great
2) saw is powerful but quiet...quieter than my old less-powerful Delta
3) Saw is accurate and makes good cuts
4) Stops are nice and easy to read.
5) Blade is nice...
6) Accessories included are good (dust-bag and clamp). This is a bigger plus since some other manfacturers make these optional

CONS:
1) The handle is not bad but I miss the D-Handle on my old Delta
2) I have yet to find a way to adjust the saw if the stops are off. I'm sure I'm just missing something...
3) As with almost all CMS's, the dust collection is a bit lacking. I have heard the Makita is great, but I'm skeptical.

Even with the small issues with this saw, it's 5 stars from me. I'm VERY satisfied...

I've been a professional highend custom builder for 17 years in which time I've bought several miter saws. There's three things I look for in a good miter saw. Consistancy, accuracy & value. The Bosch 10" sliding compound miter saw is a top contender in all categories. The only draw back is it's ability to only bevel in one direction. If this is a must have feature then step up to the new Bosch 10" slider for a few more bucks.

There are lots of reviews for this tool. This was my second Bosch purchase (the first was a random orbital sander that I also adore). The level of quality has been superb on both items.

I love the ergonomics of the device. Everything is where you expect it to be, and everything feels incredibly solid as you make your adjustments, lock them down, set your workpiece in, and especially when you are making your cut. There is NO PLAY in the sliding mechanism, nor is there in the miter adjustment or in the bevel adjustment.

It's a very heavy tool, but it needs to be to have the solid feel that it has. I purchased a mobile miter saw base, mounted it to that, and I highly recommend you do the same. (See my review on the mobile base, a Delta 50-155). You do NOT want to be lugging this thing out all the time because of the weight.

The only complaint is the really lousy dust collection. However I see this tool as being most useful in its mobile state, so whenever I use it I set it up outside anyhow. I am not aware of any sliding compound miter saw that has an effective dust collector, but even if there were one, you could not get me to trade mine out for one!

Another pointer - definitely get an extra Bosch clamp or two. They are not very expensive, are very well made, and make your job much easier, especially if you are working on your own.

I understand that there is now a Bosch that bevels both directions. If you decide that it's important to you to be able to bevel both left and right, I'm sure you would be happy with this choice also, but I have never found it to be complicated to work with only the right bevel capability on this saw. It's simple math.

Bottom line, I cannot imagine a higher quality work tool and I know you will be happy with this choice. I would go further and say that my experience with Bosch would lead me to look at Bosch first for any corded power tool. (For cordless, see my reviews on Porter-Cable, which I also highly recommend.)

Personally, I think woodworkers around the country should trade in their power tools for credit and replace them all with Bosch.
I started using bosch tools over 12 years ago in a furniture shop, and my first experience with their tools was a jigsaw, which apparently has since reached legendary status.
This particular jigsaw was thoroughly abused every day for years. We'd burn through all the sears brand stuff, replacing them every few months, but the Bosch tools only needed the occasional cleaning and replacement blade.
I saw first hand the kind of torture Bosch tools could withstand and have been a devoted fan ever since.
In addtionl to the durabiltiy inherent in nearly ALL their tools, i've also found them to be highly ACCURATE, which is absolutely required when crafting furniture.
This particular tool carries on the long tradition of high quality, tough, accurate and well designed tools from bosch.
I'd give their tools 6 stars if i could.

I must admit I was worried about purchasing this saw, because it seemed to cheap (price) compared to comparable Dewalt, Porter Cable, makita saws. However, bosch makes great equipment, and they came through with this one as well.

After setting this up and testing it, I have to give it 5 stars simply because the price is unbelievable, and the saw performs flawlessly. There are a few minor things I would change if I could, but they are minimal and not very important, only matters of design, convenience, etc. see below.

One negative reviewer stated that the detents weren't adjustable, and couldn't believe Bosch would build a saw without adjustments. This is incorrect. In order to adjust the angles on a miter saw, you need to change the relative position of the detents to the fence. On some saws, like the Porter cable, you can move the detents. On others, such as this, you move the fence. (The detents are cast in position and can't be moved). My saw wasn't correct out of the box, so I followed the instructions and loosed the fence and squared it to the blade with a combination square. However, this was difficult to do, and it still ended up slightly out of adjustment when tested on a board. My advice, which made it a piece of cake: Pick a 12" piece of wood with a perfectly straight edge (I used MDF), make a cut, check the square, adjust the fence and retighten, make another cut, and continue until you are dead on square at 90 degrees. This method wasted a little bit of wood, but I got it adjusted dead on accurate in about 5 minutes, and no fumbling around with a square against the blade.

Once I got the 90 degree detent in position, I checked the others making 45 degree cuts in both directions on 6 inch material and the results were PERFECT. I mean dead on perfect. I can't imagine better miters.

Another reviewer said there was play in the detents of 1 degree or so. If you put it in a detent and don't tighten the knob, there is some play, but only like 1/4 degree or so, and if you tighten the knob as you are supposed to, the play is taken up and the blade centers on the detent dead on in the middle, same place everytime I try it. If used correctly, there is no play.

Other positive's:
-Comes with a quality 40 tooth blade. You don't have to buy a new blade to get good results with this saw. Most of the others come with a cheap blade that will cause tear out on your trim.
-Wrenches included for fence and blade, and mounted on the rear of the saw in convenient places. you'll never find yourself without the wrench you need.
-Adjustable slide on left end of saw gives you a little bit of extension in the table, about 4-5 inches.
-No upward kick with startup like my old delta saw, and what I hear from dewalt. I hated my old saw for that. I would line up the cut, and then when I hit start, the saw would kick and make my board jump, and I'd have to line it up again with the blade spinning. This saw doesn't do that, I'm happy to say.

Negatives:
-Dust collection isn't very effective, but I've never seen a miter saw that is. Seems average to me.
-Handle is vertical position. I would prefer horizontal like the dewalt, but I don't think it's worth paying the extra money. Then again, I don't make miter cuts all day everyday.
-Blade guard is a little too cautious in my opinion, and not adjustable. Guard stays pretty low to the table, so when you are lining up the cut, you have to have your eyes nearly level with the board to see your mark. In other words, the guard obstructs your view if you are looking from above the saw at all. Easy fix is to mount the saw in a high position, as most people do with miters anyway. However, if you put the saw on the floor temporarily to do a few quick cuts, this can be a real pain.

Overall, a lot of thought went into the design of this saw. It is well constructed, the quality you'd expect from bosch, and dead-on accurate. It does everything I would expect it to do and more, and at a price that I still can't believe. I had reservations before I bought it, but now I'm thrilled that I did. Thanks Bosch!

It's great for slicing wood (walnut,maple,redwood,and mahagony) very clean and precise.It can slice just about anything.I have read that the Makita has a nice blade included with their model and the Hitachi with the LAZER sounds cool ($500.00) but this saw was excellent for the price.

Having my own business I have to use quality tools. So when it was time to upgrade I went with the Bosch 3915 slider,Bosch 4007 tablesaw and the Porter Cable compresser/nailer combo. I couldn't be happier with my choices. Amazon is the place to buy your tools but I have nothing good to say about how U.P.S. treats shipments. I watch as he dropped my saw from the truck to the ground.

I just purchased this saw and right out of the box I checked all the settings. After zeroing the fence to the blade I checked the accuracy of the miter 45's. 1'st I discovered that the 45 detents were off (and not adjustable) Bosch provides a detent override for this purpose. After disabling the detents, I discovered that the Miter scale is not accurate either. The scale is a cast in feature (not machined or adjustable)

The good news is that the saw runs good, cuts good and is very accurate and repeatable at the zero degree mark.

I was in the market for a miter saw for a whole-house crown molding project. I spent a few weeks going to local stores as well as reading online reviews. I settled on the 3915 from Amazon.com and have been very pleased with my decision. Below are some key findings:

1) A quality built tool with thoughtful design. You'll read some complaints on the dust collection bag but I find that it works about as well as most out there. If you're really concerned with dust, hooking up a shop-vac should do the trick.

2) Value!! This is a 10" slider for the price of most chop-only saws. The single bevel can sometimes mean a bit more effort but I simply couldn't justify paying nearly 50% more for a dual-bevel sliding Bosch or Makita. And the 10" slide handles wider pieces of wood than its 12" chop-only counterparts.

3) The only weakness I found was the bevel angle markings. The tool was true from the factory but the markings are a bit hard to zero in on. That being said, I can't say that I had any angle issues with my finished pieces but it just takes a little getting used to setting it.

All in all, I would challenge anyone to find a better value in a sliding compound miter saw.

I had this saw for 5 years now and I am somewhat satisfied with it. I cuts very smoothly and I I love the indents and the wide cutting range of the saw. That said, the dust bag doesn't really work which everyone knows. But the thing that really bothered me was the guard. It uses a ballbearing/cam mechanism in a awkward way and if you use the saw alot, the screw which hold the ballbearing strips out. I had brought it in for repairs once but it didn't last. I had to alter the guard mechanism to get it to work properly. If I had my money back, I would buy a makita 12" sliding compound. (I used and love that saw)

I am a professional cabinet builder, bought this saw in Sept. 2002, and have had trouble with the switch going out. The motor is no longer as powerful as it used to be either. I have bought a Makita now to try out for a few years and am selling this one while it still has a little life. I don't believe this saw is made for commercial work. Note, I have NOT abused this saw, it just has had a lot of use day in and day out.

I received my Bosch 39-15 yesterday and putit immediately to work. I am re-doing a basement room and had to cut many boards for trim. Out of the box it was in perfect alignment. Quickly read the instructions and off I was. I didn't experience a problem with dust any more than my chop saw by Dewalt. It is very smooth. The unit has a very smooth glide and moving the saw head to make the cut is effortless. It took me months to decide which unit to buy. This was the must sturdy unit I evaluated and it's ease of use helped me make my decision. Amazon had the lowest price. Ordering on line was great. So simple and fast. It was delivered in five days. If you want to save a lot of money, buy this unit. There isn't a saw that can compare to the quality of build on this saw.

I received the Bosch 3915 today, and of course had to test it out. First of all, I was impressed with the overall quality of the saw and was very impressed by its weight. It's heavy, and I have yet to find a really easy way to pick it up and move it around. I'm assuming that it's meant to be mounted on a bench or stand, as opposed to being moved around from place to place. I was also impressed with the manual, since it seems to be written in English and for the most part explains things very clearly. Often, manuals that come with tools made in other countries suffer in their translation. I did experience one situation that was not explained well in the manual, however. I tried cutting a dado by using the depth stop feature, which in itself is easy to adjust. The problem I encountered in making a dado is this: When the piece of wood is placed on the table and pushed against the fence, the blade does not make a uniformly deep cut all the way through the piece because of the curvature of the blade. I assume that there are two solutions to this problem. One would be to turn the piece around and make the same cuts from the opposite side. Another wouuld be to put a second piece of wood against the fence and then put the piece in which you want the dado in front of that piece. Either of these methods is rather inconvenient, but maybe I'm missing something. If anyone has a solution, please let me know.

Previous to using the saw, I checked all of the adjustments as explained in the manual and found that they all seemed to be set perfectly. I also cut several test pieces and checked them for squareness and various angles; they were all perfect. I haven't yet used the saw for crown moulding, so I can't comment on how well it does for that purpose. As far as the operation of the saw itself, I was generally satisfied. Since I have been using a miter saw that has a vertical handle most of my life I had no issue with the handle on this saw. I do realize, however, that some folks prefer a horizontal handle. The one feature I don't like is the placement of the power switch lock-off button that has to be depressed before the power switch can be pushed in. No matter how I contort my hand I can't find a comfortable way to depress both buttons at the same time. On my other miter saw, the lock-off button is perfectly placed so that both buttons can be easily depressed at the same time.

Lastly, I have to agree with other reviewers about the uselessness of the dust bag. I tried turning it it every direction possible, but nothing helped. It doesn't collect much dust regardless if I make chop cuts or sliding cuts. And, yes, I do slide the blade from front to back as explained in the manual. So, overall, I would give the saw 4 1/2 stars, but since that's not possible I gave it the four stars because of the lock-off switch, the dust bag, and the dado situation.

Background - I traded my 10" Delta CMS so needed a new one. I settled on getting a 10" slider based on the capacity of the sliding saws. I did not want a 12" SCMS due to excessive weight and size. Plus, I don't need that capacity. I decided against a 12" regular CMS because a 10" slider can actually cut wider lengths and 10" blades are easier to find and cheaper. Yes, a 12" CMS will cut taller pieces, but I have other saws I can use in this situaton (extremely rare for me).

Positives
+ lots of metal and very little plastic which adds weight but hopefully adds to durability
+ easy to read scales
+ tall fences
+ really solid detents; yes, there is a little play if you don't lock them in, but how long does it take to turn the knob two times?
+ wide foot print which translates to sturdier operation.
+ nice stock blade that I may actually keep on the saw.
+ almost dead-on out of the box as I spent more time double checking everything than making one minor adjustment.

Negatives
- not as portable as a regular 10" CMS, or even a 12" CMS as this saw is heavy.
- handle not the most comfortable
- single bevel (but I have never had a dual bevel and will not pay $200 or even $100 more for this feature)
- extensions must be purchased seperately; these only cost about $17, but a lot of other saws have them as standard features.

Other 10" SCMS considered (and why they were not purchased)
* Bosch 4410 - about $200 more for a few extra features: front bevel controls, dual bevel, adjustable handle and a fraction more power. IMHO these were not worth $200 more.
* Porter Cable - price seemed competive and reviews were favorable. However, I had a friend who had a Delta and I didn't like it. The PC model is not the Delta, but since they are part of the same company they may be too much alike for me.
* Hitachi - Looked at this saw first hand and did not like it. There was a lot of plastic on it and it was about $90 more ($140 if I wanted the laser). Also, the foot print seemed small. I just did not have confidence in this saw.
* Makita - I was really big on this saw but could not find one to look at in person. I read a lot of mixed reviews and $450 is a lot of money to spend on something you can't touch before hand.
* Milwauke - They make a lot of great products. Their regular CMS's are great and really accurate. However, customer and magazine reviews have been mixed on this one so for the $100 higher price tag I decided to pass.
* Delta - the Delta was never really in the running due to first hand use of a friends.

Many folks have complained about dust collection. First off, show me a miter saw that gets 100% of the saw dust anyways. I made 20 cuts on 4x4's and there was a lot of saw dust on the saw, stand and ground. However, I reached back and felt the bag - it was 75% full. If this is the biggest knock on this saw, I am looking forward to all my projects.

Half the price of a Dewalt 12", did not need that big of saw. Came with a clamp, did not have to pay extra, all dustbags are pretty much useless, I've always got sawdust when I cut a piece of lumber, hmmm. Top value as far as I'm concerned.

After using this saw for 3 1/2 years I definetly have mixed feelings. the split fence on the left was not in line with the right side and in one piece with no easy fix, a constant nagging problem. But it had a good motor, and adjustability was acceptable. If you notice all my referances are in the past tense, because as of this afternoon the thing is laying in two pieces in my work van. The casting broke at the turntable. I take great care of my tools, I buy the best and expect them to work very well for a long time as have the many other Bosch tools I own. I will not buy another Bosch chop saw unless they give a pro rated discount on a new one. This saw should not have broken so easily. If you work out of a van or truck,like every other carpenter on this planet does, I can't recomend this saw, it can't stand up to normal handling. If you want absolute accuracy from the fence don't buy this saw it may be hard to fix the split fence. I hope others who have this saw have better luck than me.

THE DUST BAG/PORT IS USELESS. I'VE NEVER USED A SAW THAT MADE MORE OF A MESS. I EVEN TRIED HOOKING UP A SHOP VAC TO THE PORT. IT MADE NO DIFFERENCE. HEY BOSCH !!!! IS THERE A SOLUTION ??

AN OFFSET MOTOR WOULD BE NICE. THE HOLD DOWN CLAMP ALWAYS SEEMS TO GET IN THE WAY. YOU CAN WORK AROUND IT, BUT IT WOULD BE NICE. (LIKE THE MAKITA)

Being a rank beginner to woodworking but not to power tools, I purchased this miter saw as a starting point to my woodworking hobby. I needed it to construct the window seat frame in our new log home. After 10 cuts on 2x4's, the switch shorted out on the saw. I contacted Bosch and found a tool supply store who could do the warranty work - simply replacing the defective switch. After 4 weeks, they finally received the switch from Bosch and I was back in business. They stopped carrying Bosch tools because of the delays in getting parts and orders from Bosch. If I had ordered a Makita or Hitachi saw, I would have been repaired in less than a week. I'm glad I bought the saw but it was a toss-up between the other 2 and $$$ was a factor.
Beware of repairs for your Bosch tools - be prepared for a long wait for parts.

I'm told this saw has been discontinued. I saw Bosch's new 4410 at a woodworking show and it's one really nice saw, with more features than this (notably the handle, which swivels to wherever your hand feels more comfortable) and it's rumored to have better dust collection. It's also well over five hundred bucks. This one cost me $354 and I'm very happy with it, thank you very much. Yes, even with a shop vac hooked up, it throws sawdust. I'll build a hood. Yes, it only bevels one way. I can flip the board. It's got a nice, solid precision feel to it and it makes sharp clean cuts. It was calibrated right out of the box. It's great for cutting long stock, makes perfect 45's, and it'll slice through a 4x4 and a 2x10. That's what I need. Maybe someday I'll upgrade but this saw is going to serve me just fine for years.

I purchased the Bosch 3915 several months ago. It sat unpacked for a couple of months before I was able to get around to using it. My experience with it thus far has been less than stellar, contrary to most of the other reviews in this forum. My particular saw will NOT cut square - I've tried adjusting the fence and the bevel zero stop but cannot get the blade square to the table or fence for the full length of stroke. The blade twists right to left just slightly as it travels through its stroke (slide). This indicates to me that there may be a misalignment problem with the slide rails, something that cannot be adjusted by the user. Not only that, the fence casting is crooked - you can lay a straight edge on the table against the fence and there is a small gap on the left side. I've contacted Bosch about this but have not heard back from them yet. Since the saw isn't cutting square, you can imagine what sort of problems that presents when trying to do finish work such as mitering crown molding. I looked at several other saws in addition to the Bosch and selected the Bosch mainly on the strength of its user reviews and the electric brake feature. At this point, I'm disappointed with the overall performance. Don't get me wrong, I do like the saw but for the money I paid, it should at least cut square. I'm hopeful that Bosch will have some suggestions for me about how to get the saw either adjusted properly or repaired so that it will cut like it should. Otherwise, I'll probably talk to Amazon about returning the saw and exchanging it for something else. It looks as though I may have gotten a "lemon".

This Bosch Slider is an absolute delight to work with. I used to have a craftsman miter saw and this one is so superior it makes the craftsman tool look like a toy. The supplied blade is smooth and precise. The overal product is very well executed and the performance is solid. Everything is perfectly aligned and the miter angles are as accurate as you can get. This tool is a real pleasure to work with and way cheaper than the equivalent Makita or Hitachi models. A real winner in my eyes.

I have used my new saw a few times now and really like the saw. As stated in many of the other reviews, the dust collection system is horrible. I even removed the dust bag and attached a vacuum and still had saw dust all over. I purchased the extensions and a spare clamp with my saw. The spare clamp is not as nice as the one that comes with the saw. The blade that comes with the saw is a quality blade and the overall machine feels and looks sturdy. Bosch put a lot of time and thought into this machine.
Great saw at a great price!

I bought this saw to be attached to the Delta Universal Stand and on that stand it is a very substantial rig. The saw came out of the box only needing a slight adjustment for bevel.

As some have already said, saws cut therefore create dust, and this saw is no different than any of those so don't expect it to be.

This is a very smooth running, accurate power tool, though one or two changes would make it better:
1)Horizontal handle - I had an old cheap delta saw that had it and it's a GREAT feature.
2)Include the out feed supports. I'm tired of manufacturers selling just the basic tool and then selling all the accessories to make the tool fully functional separately.

I gave it 4 stars only because 4 3/4 wasn't an option and I think 5 stars is reserved for an item with no criticism.

Highly recommend
