Rated 3.6 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by great for aluminum I needed to drill holes in the aluminum sliding glass door frame to mount in concrete with Tapcons. In order for the door to slide by when done, the Tapcons needed countersinking. While my drill bits dulled in the aluminum and gave me a headache, when it came to using the countersink bit it was powerful and cut many holes without dulling or slowing. The last hole drilled as easy as the first. Perfect tool for my aluminum application. June 7, 2016
Rated 1.0 out of 5.0 by Leaves a terrible finish Chatters leaving a rippled finish in wood. I would not purchase again April 27, 2016
Rated 5.0 out of 5.0 by Did the job well the counter sink did what it was manufactured to do -- easy to use, produced clean accurate countersinks in a wood flooring transition. I've only done three countersinks with the tool at this point, but would rate it excellent. January 12, 2016
Rated 2.0 out of 5.0 by Don't waste your money Terrible not one sharp flute. Wound up burning the oak I was working with. Might work on balsa wood? August 4, 2015
Rated 5.0 out of 5.0 by Very Nice Countersink Need to do a few countersink in wood and some steel angle irons. It did a great job in the wood and steel. When using it for steel make sure you use a lubricate so burn up the countersink. June 11, 2015
