1 1/8" x .145 x 5/8-11
Professional grade crown segment design for easier slurry resistance. Minimal segments combine with an ultra-high diamond contect for some of the fastest-drilling bits on the market without sacrificing life.
The best choice when it comes to drilling though concrete with either a high psi or any sort of heavy reinforcement.
Wet use only 5/8-11 thread connection Also great for laboratory core sample testing Custom diameters available
