Review on 5Pcs Of M35 Cobalt Steel Drill Bits With Straight Shank For Efficient Cutting Of Hard Metals by Adam Hogan

Revainrating 5 out of 5

Cut through SS like butter

I had to drill and tap a few anchor rings made of 304 stainless steel. My cheap wood bits would hardly touch it, but this bit went right through it with some cutting fluid.

Pros
  • The bit withstood some heavy drilling and did the job I bought it for, drilled some steel with it.
Cons
  • Only suitable for cutting hard metals such as stainless steel, titanium alloys, etc.
