Really? You want me to review a drill bit? Umm, it put a hole in the material I wanted so I guess it was at least good.

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!

HD really wanted this review done; sent two requests. So, ok. I’ll write a review on a tiny, 1/16” drill bit. Here goes. I secured the drill bit in my drill, put the tip on the mark I’d made on my steel bathroom door, pulled on the power trigger and….drilled a hole. The tiny drill bit met my expectations. Well, there you go. Review done.

Strong drill bit. Works great on metal and last a long time.

They are really hard steel to work on hard to bore metals. Good stuff
Camryn Zieme (verified owner) –
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.

I break bits pretty often when hand drilling and these bits are cheap enough that I am not upset when I do and sharp enough that I break them less often. Great for mild steel.

Working on a deck project that requires me to drill into aluminum posts. This drill bit appeared to be the best that Home Depot had to offer for a metal project.

the drill bit is a little expensive but it performs very well

I have doors that are made from recycled wood. I tried to drill holes through the door with a cheap-o drill bit I had and it took over 10 minutes to get one hole drilled. I bought this drill bit, and it turned that time into 10 seconds per hole. I wish I had purchased this before making the first hole.

The cobalt bit drills stainless steel well. The Milwaukee brand performs much better than the competition.
