Review on 5Pcs Of M35 Cobalt Steel Drill Bits With Straight Shank For Efficient Cutting Of Hard Metals by Troy Larson

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
  • For Metalworking - Particularly Successful In Cutting Through Hard Metals(Hardness Less Than Hrc38°) Such As Stainless Steel And Cast Iron, Although They Can Be Used For Softer Materials Like Copper And Aluminium, Too. Not For Hardened Steel And High Carbon Steel.
Cons
  • Might be difficult to find replacement pieces for specific sizes
