Dewalt Cobalt Drill Bit - 1/2'' is rated 4.3 out of 5 by 21.
Rated 5 out of 5 by from Does a great job. I purchased this drill bit after having quite a bit of trouble drilling through a heavy steel assembly. Rather than waste money on a generic black oxide bit that probably would have done the job but no more I chose to bite the bullet and get the best bit I could get. I chose this cobalt steel bit in the hope that I would drill the hole and still have a useable bit. Well the bit work great cutting through the steel like butter with minimal pressure. The bit seems to be unaffected. The only down side is the cost of the bit but to tell the truth I will likely buy other bits as I need them even given the cost.

Rated 5 out of 5 by from Great bit for hardened steel. Working on a steel project. My bits were just spinning on this steel. Borrowed friends larger drill and his steel bits but again no luck. Broke down and stopped spinning my wheels and drove to Lowes. Bought this bit and it went through the steel in seconds! I used a light oil to keep the bit tip oiled. This is a great bit. It also has a 3/8 chuck end so it fit in my Dewalt 8-Amp 3/8-in Keyless Corded Drill did a great job. If you are working with steel and need a 1/2" hole, this is the bit.

Rated 5 out of 5 by from Great bit, but... These bits are awesome! I drilled through multiple pieces of cold rolled steel and the frame of my old pickup. The only problem I had, is that I broke 2 of them while drilling the frame. I want to emphasize that this is not a fault in the bit. This is misuse on my part, if you will. Will drilling the steel stock, I used a bench vice and kept the drill steady. Drilling the frame, however, made this difficult. Be careful of angles and catching with the bit. It wasn't the first, second or even third catch that broke the bit. I eventually lost count. I'm just glad the bit gave out before my wrist did. :) Overall, awesome product! I fully intend on purchasing another 1/2 inch, plus other sizes to be able to more easily do metal work. Again, the failure was not in the bit. It was in my usage.

Rated 5 out of 5 by from Heavy duty drill bit Tried other drill bits to get holes drilled for a bracket in some 1/4 steel and my other bits only scratched the surface, got to hit and spin. Bought this and drilled all my holes in just a few minutes with no problem! I will be buying more as needed.

Rated 5 out of 5 by from Like butter through strut channel galv steel Was in a bind after eating up the titanium hss bit I had trying to meet a looking deadline. Needing to get something that worked first time, without having to return to the store, I spent a little extra the cobalt bit. I was not let down - this bit did not slow down going through hole after hole in galvenized strut channel (superstrut). Must have made over 40 holes and it didn't show signs of wear. Buy the right tools for the job and it'll cost you less in time and trips to the store in the long run! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Awesome drill bit Had to drill out lug studs to get wheels off of my car. This bit lasted long enough to drill out 2 1/2 lugs. I tried other brands that wouldn’t last long enough to drill even one lug although they were priced the same. I will purchase these bits again. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Drill Bit That Works Excellent drill bit for exceptionally hard steel. Tried other type metal bits and they failed to penetrate galvanized steel tubing even with pilot hole. Titanium coated bits are a joke compared to cobalt. Spend a few quarters more for this drill bit. [This review was collected as part of a promotion.]
