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 Joshua Days

Revainrating 5 out of 5

Sharp! Needed to move it to my Grizzly radial, too much bite for my table top drill to handle.

Like the very sharp cobalt edge. Using it to drill articulation holes for tracking solar array linear actuator mounts. No rating on longevity, that takes usage and the passage of time to determine.

Pros
  • As advertised
Cons
  • The 14mm size may not be suitable for all drilling needs, limiting its versatility
