Advantages of Single Roller Bit

High-Temperature Resistance and Wear Resistance

The floating bearing structure, floating element is made of new materials with high strength, high elasticity, high temperature resistance, high wear resistance characteristics is made, the surface of solid lubricant processing.

Strong Impact Resistance Capability

High strength and high toughness cemented carbide teeth, high precision lathe technology and cold pressing technology have been used to improve the impact resistance of the teeth.

Strong Anti-Seizing Capability

Optimization design of the tooth row number, number of teeth, teeth height and unique alloy tooth shape, give full play to the cutting ability and cutting speed; Inner hole welding antifriction alloy bearing, improve anti bite ability.

Excellent Sealing Performance

The high temperature of 260 degrees centigrade, the new grease and low wear, improve the ability of high temperature resistant sealing drill lubrication system.

What Our Clients Are Saying

Marco T.

This bit's durability is unmatched. We pushed it through extremely abrasive shale formations that usually wear down bits twice as fast, and it held up beautifully.

James R.

The penetration rate on this single roller bit saved us a full day on our project. It's now our go-to for consistent, predictable performance in medium-hard rock.
