Rotary Drill Bits For Mining

Tricone bits - Verified in the lab, for superior performance in the field.

Our tricone bits product line promises the highest performance, reliability, and availability. This effectively results in a lower drilling cost. With sealed bearing product line, takes the guess work out of drilling. Our bits are designed to increase bit life even further where the application presents restrictions to drilling.

1. Elasticity Sealed Roller Bearing Bit
Cutting Structure: The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for steel tooth bit.
Gauge Structure: Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hard facing on the shirttail increases gauge holding capability and bearing life.
Sealed Bearing Structure: 1. Abrasion resistance and seizure resistance of the bearing are improved. 2. Premium O-ring, Optimal seal compression and curved seal structure can enhance the seal performance.

2. Air Cooling Roller Bearing Steel Tooth Bit
Cutting Structure: The wear-resistance of teeth is enhanced with premium tungsten carbide hard facing on the tooth surfaces for steel tooth bit
Gauge Structure: 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.
Sealed Bearing Structure: Air cooling roller bearing package. Balls lock the cone which reduces the probability of cone-dropping to minimum.
