YOU GET WHAT YOU PAY FOR...
These bits do a great job. I'm about to buy spare drill bits for the set. True, there are cheaper versions. I've destroyed several. The "cheaper" versions have set screws that strip out quickly, or spin because you can't tighten them enough.

Great but expensive
Somewhat of a funky taper on the drill bits, but they work well. Not as adjustable (drill bit length) as I thought or as the packaging would lead you to believe. Finally, these are many times more expensive than some of the cheaper countersinks out there. If you have a "serious" need for countersinking, then this is a good set.

Versitle Drill bits
I had an opportunity to purchase and use a set of these tapered countersink bits on a job where we had hundreds of countersunk pilot holes to drill. I used a drill bit stop placed on the shaft of the countersink to regulate the depth. They performed flawlessly. I later used them to pre-drill holes in plexiglass by turning the countersink around backwards and using a rubber washer as a cushion. I am a believer in using the right tool for the right job. I haven't ever seen any better bits of this type from any other vendor. *****

Makes woodworking much easier!
I bought thes bits in july as replacments for my broken crafstman bits...it makes fastening cabinets ten times quicker .instead of havin to change bits everytime it drills and countersinks all in one pass!i recommend this to any woodworker hobbiest or pro.

Great set up
These bits with the countersink set up work great. The countersink can be adjusted to compensate for a shorter screw length. The set of three is under 25 bucks at both Home Depot and Lowes, so shop carefully. ... Read more

pricey, but works great
This is an expensive way to drill a hole, but it works great. It cuts fast and really is self feeding once it digs in. Plus it can be resharpened. If you have a lot of holes to drill use one of these paired with a high torque drill-much better than spade bits, which quickly wear out or hole saws, which can bottom out after a couple of inches. I like the Dewalt self-feed bits slightly more because they have two cutters and seem to work a little faster with less effort. ... Read more
