Review on High-Performance Cobalt Jobber Length Stainless Cutting Tools - 64 Inch by Brett Jarvis

Revainrating 5 out of 5

quick response and delivery

I have these drill bits purchased for use in installing doors and hardware, bits work great when new unfortunately there is concrete in the door frames and when the bits "touch" the cement they will leak however the beats work as advertised.

Pros
  • JOBBER LENGTH: 11/64" cutting diameter, 2-1/8" flute length, 3-1/4" overall length, 135 degree collet, straight shank
Cons
  • little things
