Tri-cone roller rock drill bit

1.Tri-cone roller bit 2.High wear resistance cutters 3.Strong cutting structure durability 4.Fast delivery

Features:    tri-cone roller bit

Roller bit also named tri-cone bit, typically they are used for oil & gas drilling, but now roller bits are also used for mining quarrying, water well drilling, etc. different rock formation with its different categories and perfect efficiency.

1. High precision journal bearing and Scientific Hydraulic design.

2. The durability of premium tungsten carbide inserts is improved with new formulas and new techniques.

3. Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hard facing on the shirttail increases gauge holding capability.
