Rated 4.4 out of 5 by 10 reviewers.
Rated 4.0 out of 5.0 by Just what I needed Bought this to countersink screws in a bench I was making. It worked great, but went dull quicker than I would've liked. I got the bench done, but I'll have to buy a new one for the next one I build. September 5, 2013
Rated 5.0 out of 5.0 by exellent product i use this to chamfer primer pockets in brass when reloading , takes out the crimp or trims the sleeves , some brass companys put in stays sharp after over 1000 pieced of brass , good quality of steel August 12, 2014
Rated 5.0 out of 5.0 by Great product I have only used this in hard board so far, but it cuts clean, and didn't go too fast to tear through the wood. June 4, 2014
Rated 5.0 out of 5.0 by Great product Used this on a cordless drill as well as a drill press. Worked great on both. Drilled about 400 1/2" holes and bit still drills quickly and cleanly. May 22, 2014
Rated 5.0 out of 5.0 by Perfect part Does perfectly what I need to do in my day to day work requirements. April 22, 2014
Rated 3.0 out of 5.0 by Useful but cheap I like the hex shank because I've used this bit frequently on cedar fencing, and if I need to put a screw right through a knot I just pop this bit into my impact driver, countersink the location, and then switch back and set the screw through the knot without having it stick up or crack the board. About the quickest solution to a common problem. That said, the countersink is uneven and not for finish-quality. Also it got dull fairly quickly and is harder to operate. April 28, 2013
Rated 3.0 out of 5.0 by "5 cutting edges to reduce burrs and roughness" aren't quite enough. Doesn't actually create the smooth countersink they advertise. More star shaped than anything else. It works if you drive your screw in hard, but it's far from ideal. August 21, 2013
Rated 4.0 out of 5.0 by Not Bad Good initial countersinking, & de-burring, but smallish cutting flutes, will load with material (especially hard woods, & corian types) June 4, 2013
