CUSTOMER REVIEWS

Rated 3.5 out of 5 by 11 reviewers.
Rated 1 out of 5 by This product is greatly overstated I was drilling some 304 stainless and needed a new set of bits up to the task. I choose these based on other reviews and the fact they are cobalt. I was a little nervous about the 143 degree angle. Long story short, they wouldn't cut. I tried different speeds, oils and even pressure but no luck. I ended up grabbing an old Mac bit that cut right through. Ridgid claims that with this tip, they wont walk. I found they walk quite a bit. I would try a different brand with 135 degree angle as opposed to these. For the skeptics out there, I have past experience as a machinist so drilling in soft stainless was old hat. April 15, 2013
Rated 4 out of 5 by Rigid Bits My drill bit of choice. They cut quickly and seem to last longer than others. They cost a little more, but worth it. August 19, 2014
Rated 1 out of 5 by Did not do the job My original review seems to have disappeared. I tried these to drill out 3 exhaust flange bolts of stainless steel. The bits dulled quickly and after using 4 or 5 different ones I stll was unable to get through. They were returned for a refund. January 16, 2013
Rated 1 out of 5 by poor quality product Needed to drill into some stripped screws to extract them, thought these cobalt bits would do the job. Nope, threw up some smoke and sparks but would not go through no matter how hard i pushed, just wore down the tip of the bit itself. Will be returning for a refund. December 3, 2013
Rated 5 out of 5 by GREAT DRILL BITS Drill bit are great when I have to play storage wars and drill locks . July 22, 2014
