Would Not RecommendI Purchased theses cobalt drill bit to make several 3/8 size holes on my trucks lower frame to install side steps. I tapped and made smaller size holes but even that did not help. I was unsuccessful in making the holes.

Junk; do not buy
Would Not RecommendAs you can see in the photo, the bit twisted and bent while drilling MY VERY FIRST HOLE with it! This wasn't in a drill press; I was using a hand-held drill, and my wrists are not that strong.
Quality
Would RecommendI use them to drill out cylinder locks when customers lose their keys. Durable and really bite into lock

a very long lasting bit
Would RecommendI bought this bit to drill through a hardened knife handle. TiN and high speed steel would not do it. This bit worked well and is still sharp enough to drill regular steel. A good buy!
