These drills are perfect. Other than being great drills, the shanks that go into the chuck are three sided, making the bits 'spin proof'. The quaility of these bits won't let you down.

For all-around shop use, these are the best drill bits for the money. I wish it had a titanium nitride coating, instead of a gold ferrous oxide coating. The no-spin shank is great for keyless chucks on hand drills. The pilot point helps to both start straight and drill straight. The only drawback with a pilot point design is that it's virtually impossible to resharpen a dull bit to the same shape. Maybe someday Drill Doctor will come out with a drill bit sharpener that can sharpen pilot points.

I have used these bits for several projects around my house. Most notably, I used them to build some bookcases. There was absolutely no wandering when I drilled the holes for the shelf mounts. The holes were nice and clean and the bits chewed through the work piece with ease.

I have burned up many drill bits in the past, and for the price these are the best. These bits alleviate the drill bit change from having to drill a pilot hole when using larger bits. Every hole is dead on. No drill bit traveling or pulling of the wood or steel. I have used these bits to drill through wood, 1/4" steel plate and plastic. I have had no problems with any of the materials. The holes are straight and clean and right on the measurements that I needed. If you require an accurate hole being drilled, then there is no other drill bit to be using.
