8" Water Drill Bit Spherical Concave Face DHD380-203MM For Hard Rock

Product Description

Five basic designs are available: Convex, Flat front, SpeedBit, Concave, and Rocket bit. These are designed for specific applications for all rock types, hardness’s and conditions.

Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application. In most cases, the focus is on productivity, so the fast cuttings removal features of the SpeedBit and Convex/Ballistic designs are preferable, to ensure the

buttons are cutting clean, with the minimum of recrushing.
