Review on Tungsten Carbide Rotary Cylinder Grinder by Matt Venable

Revainrating 2 out of 5

Very fragile but sharp

They chip very easily and need to be handled with care. I've used mine in a powerful 15,000rpm air motor and almost destroyed it in seconds on 304 stainless steel, when I used one on carbon steel and slowly inserted the cutting surface it took about 15 minutes or so.

Pros
  • Good price
Cons
  • Some difficulties
