Single Cone Bit Coal Mining Tools For Core Barrel and Hole Opener
For Machines :The products adapt to the machine with all the
performance features such as a high feed rate, a long service life
and short tool changing 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.

Product Details
Single cone bit is a kind of deceleration bit, which is the speed
of cone is smaller than the speed of drill, mainly disorderly
cutting broken rock. It is suitable for old well sidetracking and
deepening the slim hole drilling operation under high rotary speed
and drilling pressure.
Cases for Roller Bits
Application
Shipping & Delivery
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
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
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
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.
