DEWALT Countersink Drill Bit Set #6, #8, #10, 3-Piece (DW2535)

I started using these DeWalt spiral drill/countersinks years ago when building an ipe' deck. EVERY screw had to have a pilot hole. These three sizes are a good combination for most sizes of screws. Could use one longer, but you could buy that separately. Be careful not to overheat these, as they will break, but other than that, they cut fine, and stay sharp. I speak from experience, after using them in hard, hard, ipe'. I usually get a set every couple years or so, and depend on them for clean screwing. The countersinks are great - the set collar is not too bulky, so you can get it into tighter places than some other designs I've tried. These break if you hit another fastener (that's operator error) or bend them while drilling (also op error). Having overheated them in ipe', I gotta say they are pretty amazing. They continue to cut, making clean holes, at least until you break off the tip and reshape it...they still work, even then, just not as well.

I love these things for countersinking. I was building drawers for a pantry. I wanted to countersink the screws so that I could set them and cover them with wood filler so they aren't visible.The points on the bits allow you to drive them exactly where you want (on pine, for sure, harder wood might be different but I did okay on maple and oak). Stick that needle point in the spot you want the pilot hole and it doesn't walk at all. Just bites down and drills it out.I don't know how they'll last, and if you break that tapered bit I don't think you'll be able to replace them.But I really like how they work.

Like all dewalt these also are good quality. I’mA longtime woodworker and bought these a few times.

These work well, but like all bits if you drop them they can develop cracks or break especially if you drop a drill with one in it. Very aggravating when you drop it or knock the drill over and break the one size you need. Wish they had a pack of 3 of just one size. I use a ton of #8s very rarely use 6 or 10s. Good value though.

Still using these months later, my first and hopefully last countersink bits! Good for wood working!

One should never drive a screw without first drilling the right sized hole, this set is perfect for most carpentry projects. As with any bit hardwoods can be a challenge and these bits will snap if you push them to hard in ipe!

Drilled pilot holes with counter sink made new stairs.

These work very well. Easy to adjust and the depth lock is secure.
