1.Tungsten carbide insert bit, TCI bit, button bit
2.Sizes range from 3 7/8" to 26" .
3.Reliable bearing and lubrication sys
1.Cutting Structure
The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques.
2. Gauge Structure
Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.
3. Bearing Structure
Air cooling roller bearing package. Balls lock the cone, which reduces the probability of cone-dropping to minimum.
4. Product Application
It is suitable for mining applications.
