Amana Tool - 55229 Carbide Tipped 82° Countersink with Adjustable Depth Stop & No-

I build a lot of painted desks out of MDF and securing them with brads and screws are just the quickest assembly process. But its always been such a pain to work quick but ensure that I dont countersink the screw hole too deep, because then it takes too much work and time to fill, dry, sand, possibly fill again, and repeat. At least on MDF, the no marring feature worked perfectly and setting the countersink to only leave 1/16 of depth when the screw is fully seated is perfect. I can now countersink everything quickly and be sure that Im hitting the perfect depth. Will buy some more of these for the #8 screw as well.

Nice clean cut on countersink, no discernable wobbling, and no marks. As a carpenter of 25+ years, I wish Id bought it long ago. The cheaper countersink bits either fall apart, are not depth adjustable, dont leave clean cuts, or leave marks. Those can be fine for occasional use, but I just finished a project with hundreds of holes and this bit was worth the investment.

Nice.

These seem to be all the rage, and the concept is fantastic. However, Ive bent two or 3 bits, even in the drill press. Im not sure what the issue is, as the bits seem to be bending near where the set screw retains the bit. Kind of disappointing, especially for the expensive price point

Really great product when you are doing a repetitive set of countersinks and want to make sure everything looks consistent and professional. Great for adding plugs.

Great product!! Very practical and comfortable in use. Just a bit expensive

Very clean cutting and collar does not mar surfaces. Used it on pre-finished maple plywood and performed flawlessly.

The ability to drill stopped counter sink holes is a game changer for me. Ive been working on making fine furniture, and one of the things that has been an issue for me is consistency with countersunk screw holes.

This just flat out works great! If you are countersinking screws for whatever your project, this is just great. After a few test drills to get the depth of cut dialed in then it’s easy to drill countersink pilot holes and just assemble your project.

Im so impressed! It drills and recesses a perfect hole every time and has not marred a single surface Ive drilled into. Stained wood painted wood unstained or unpainted wood has not left even a small indention! Now, of course, if you push down really hard, the catch collar will mark your workpiece slightly, but its pretty obvious that you shouldnt do that, but you wont find the need either. LOVE that its impact driver ready, too. It IS a tad pricey for sure, but man, is it fantastic. Still very sharp after 100s of holes drilled. 100% recommended. Hope this was helpful!
