1. Elastomer (Rubber) Sealed Steel Tooth Bits

Cutting Structure

The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing 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 hardfacing 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.

Main Type Available

Size: 5 7/8",6",6 1/2",7 1/2", 7 7/8",8 1/2",9 1/2", 9 5/8",9 7/8",12 1/4",13 5/8",14 3/4",15",15 1/2",17 1/2",22",24",26", etc.
IADC Code:1-- Series, 2-- Series,3-- Series

2. Air Cooling High Quality API Steel Tooth Bits

Cutting Structure

The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing 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 hardfacing 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.

Main Type Available

Size:5 7/8”,6",6 1/2",7 1/2", 7 7/8",8 1/2",9 1/2", 9 5/8",9 7/8",12 1/4",14 3/4",17 1/2", etc.
IADC Code:1-- Series, 2-- Series, 3-- Series

3. Non-Sealed High Quality API Steel Tooth Bits

Cutting Structure

The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces.

Sealed Bearing Structure

Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone Cdropping to minimum.

Main Type Available

Size: 2 3/8",3",3 5/8:",3 7/8",4",4 1/2",4 5/8",4 3/4",6",6 1/2",7 1/2", 7 7/8",8 1/2",9 1/2", 9 5/8",9 7/8",10 5/8",12 1/4", 17 1/2",etc.
IADC Code:1-- Series,2-- Series,3--
