Review on TopLine Drill Size Cobalt 1 Pk Cutting Tools for Industrial Drill Bits by Mike Goodwin

Revainrating 5 out of 5

Good quality drill bit

Arrived on time, just as advertised. I've used it to drill multiple holes in cast iron, stainless steel, and C-1018 CRS and it's still sharp. I would like to buy it again.

Pros
  • High test scores for grip and durability
Cons
  • Not as thick as other picks
