Bought it to drill stainless steel shelves. Used the lower speed on my Ryobi battery drill as recommended on the drill package and was amazed at how well it worked.

I would like to take back my negative review for 7/64 Milwaukee Cobalt bit . The hole I was trying to drill was at the angle and at a difficult location. The drill bit is excellent. I never seen a bit flex so much and not break.P.S. HD, fix the picture and a title for the review pop up. It does not match the link!

I am new to knife making. I have tried several different drills and this was the best of the lot for drilling hard metal. Drill speed is vital to successTool speed charts are available onlineI use 600 rpm on my drill press with a little motor oil

I have been drain drilling holes into galvanized steel planters and it has been doing fine. Very pleased. I bought two just in case but now I know I won’t need the other one.

bit works great slow speed, we drill 15-20 sheets of steel roofing at a time 20 holes each sheet. lots of drilled feet by the end of the day. not the best bits in the world but will certainly work great if you know how to take care of them during use.

Great drill. A little proces but it went through 3/16″ mild steel like butter without having to drill a bunch of sequentially larger pilot holes.
