Review on High-Quality 9Mm M35 Cobalt Drill Bit For Cutting Hard Metals - Straight Shank, Extremely Heat Resistant, And 5% Cobalt M35 Grade HSS-CO by Chris Russell

Revainrating 5 out of 5

Excellent drill bit

I bought this bit specically to drill the precise size hole for installing M6 rivetnuts. It did the job that it was purchased for.

Pros
  • I haven't used them yet, but they look like they should be very acceptable.
Cons
  • May require a stronger drill to prevent breakage and damage to the bit
