Review on πŸ”§ MIBRO 492470 Cobalt Artisan Creations by Mike Rice

Revainrating 1 out of 5

Cuts through everything so far

They're strong and I've had no problem breaking, but I can feel it in them. I haven't pushed them and have so far gone through any steel, even a trailer frame, with little effort. Be sure to go from a small pilot hole (and use oil) to larger pilot holes, hold tight too because they can generate a lot of torque. I would buy again.

Pros
  • Stronger - Extra thick core adds stiffness and strength
Cons
  • Damaged
