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 Kyle Deel

Revainrating 1 out of 5

Inaccurate in my review

The drill bit was not sharpened correctly from the factory and it drilled a hole way bigger than it should have. It should drill .492" dia and it drilled .509"!l

Pros
  • Looks like a quality product that will do the job for a long time.
Cons
  • Not 5mm, but 4.9mm. I can’t fit a 5mm rod in a 4.9mm hole.
