Rated 4.0 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Finest Drill Bits These cryo treated cobalt drill bits are fantastic. I had a project that had a lot of rivets into 1/8" steel and 26 gauge sheet metal. I started the project with a TiN bit, thinking it would do the job, way too much work. These holes I made were drilled with a corded drill, free hand, standing and kneeling and in awkward positions, so it was hard to keep the drill aligned. After four holes with the TiN bit, I switched to this bit. Over 300 holes later, I was still getting curls, the bit was showing a little wear, but holes were made quickly. If you have to drill metal, use these bits... October 6, 2015
Rated 2.0 out of 5.0 by Hit or miss The quality of the bit was hit or miss. I bought several of the bits because I was drilling 100+ holes through 1/4" steel columns. The first bit worked like a charm, cut over 70 holes before dulling the bit. To finish the project I had to open three more packages to get a second bit that worked as well as the first. Product works great when it works, but it appears that there are quality control issues. February 17, 2015
Rated 5.0 out of 5.0 by Went through metal! We used to drill through an old exterior locking doorknob. Worked great! December 30, 2014
Rated 5.0 out of 5.0 by Great product, why discontinue? One 3/.16" bit drilled over eighty holes in 1/2" steel and it's still sharp enough to drill more. Used it with the Oatey dark cutting oil and variable speed hand drill. Worked like a champ. Would highly recommend. I hope that whatever they are replacing it with lasts as long and works as well. Just in case, I bought three more! September 3, 2014

Rated 1.0 out of 5.0 by 1st Use and it broke! I purchased the set of these and the first time is used the 3/16 bit it snapped in half. I was drilling in soft metal!! I went to my cheap Ryobi backup, no problems. September 15, 2009
Rated 5.0 out of 5.0 by It worked very well for what I needed a metal bit for. It was very good and did exactly what I needed it to do and the price was not too bad. February 7, 2012
