This cuts through stainless steel
Marcelo Koelpin (verified owner) –
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!

Worked well drilling on cast iron and metal.

They are the only bits I buy. They don’t clog up and stay sharp

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.

This bit worked fine for my steel drilling.

Very good quality drill bit. I was able to drill through a quarter inch thick metal plate with relative ease.

Drilled 6 spot welds successfully while other drill bits broke or dulled quite quickly.

I tried several bits to drill through hard steel. This one was, by far, the best and most durable bit that I used.

These are the best bits I have ever used. They last through many uses on heavy steel. (I recommend going slow, and putting a drop of oil on the tip every 30-60 seconds.) I used this bit to drill 10 holes thru 1/4” steel, then thru a bunch of rivets, and it is still sharp!

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