Review on High-Heat-Resistant 14Mm Cobalt Steel Drill Bit With Straight Shank For Cutting Stainless Steel And Cast Iron - 1Pc, Grade M35 HSS-CO With 5% Cobalt Content by Rodrigo Harrison

Revainrating 5 out of 5

It worked well as expected

I needed to drill some holes in a 3mm-thick steel plate. It was super easy and fast with this drilling bit. I used a metal screw to punch a small mark at the drilling position first before I started drilling.

Pros
  • For the price you can’t go wrong
Cons
  • The drill bit may be too expensive for some users, making it an impractical purchase

Worked OK to drill through 6062 aluminum. Didn''t drill a lot of holes but enough to know at least it''s not a garbage drill like some.
