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.

Its an odd size but needed it for my application. Cobalt bit should last for a long time

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 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!

Great price and good bit!

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.

Bought this to drill through a car frame rail and worked flawless. Drilled through the metal with little effort.

The best type of drill bit I use to work on stainless steel, the only bad point about them is that they are very fragile and break at the first mistake made during a manual drilling operation, but using correctly , they are the best!

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.

Worked well drilling on cast iron and metal.

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.

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.

Have multiple cobalt bits for drilling stainless on boats, work great last until I break them.

This drill bit stayed sharp to drill all the holes for the bolts that would attach new slats to my lawn furniture .Yea!

I bought this to drill through a metal plate that I could not see inside a brick wall. It did not go through. I tried it on some scrape metal and it went through clean and fast so not sure why. The other issue was I bought a Milwaukee bit extender to reach through the wall and this bit would not in fit the 1/4 inch holder.
