times. Together with the parts supply assurance, a high daily production volume, and above-average economy is guaranteed
roller bits are tools for boring into rock and earth. They are used to drill blasting holes and penetrate
both soft and hard rock materials. Products are also used in many other mining, quarrying, tunneling,
construction, geological exploration, and blasting applications. Roller bits can be classified as chiseling bits, tapered or threaded cross-style bits, anchor bits or self-drilling anchor systems,
blasting furnace taping hole bits or rods, or coal cutter bits. They feature a hollow body with multiple,
outward-extending wings.

1.Cutting Structure
The wear-resistance of the teeth is enhanced with premium tungsten
carbide hardfacing on the tooth surfaces for the steel tooth
bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit
2.Gauge Structure
Multiple gague 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 capacity and bearing life
3.Bearing Structure
High precision journal bearing with two thrust faces,Balls lock the
cone.Hardfaced head bearing surface.Cone bearing inlaid with
friction-reducing alloy and then silver-plated.Abrasion resistance
and seizure of the bearing are improved.and suitable for high rotary speed
4.Seal and Lubrication
The advanced metal seal package consists of two metal seals and two
elastic energizers.Compressed energizers ensure good contact being
kept on two sealing surfaces of metal rings by elastic force,and
achieves the bearing seal.In the drilling,metal seals are
relatively dynamic,and the energizers are static.This will improve the reliability and durability of bearing seal.The pressure
compensator system and advanced grease can greatly increase the
lubricating reliability.
