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.

Product Advantages:
a.Speedmade every new bit drilling time over 200 hours
b.Speedmade every used bit drilling time range 100~180 hours.

c. Siruite every new bit if teeth or other place are broken when you are using it in a short time,bits are all guaranteed exchange new one for free!(of cause,non-human factors)!

d. Siruite every bit have certification quality and specification for everyone in the box when delivery to shipping port!

e. Siruite have a big professional technical team around the world when you place a large order and need to technical support.

 

-WHY CHOSE US-

 SPEEDMADEDRILL is a leader in the manufacture and development of many kinds of  bits in China. We provide the best quality PDC coring drill, DTH drill, Tri drill bits etc to the market, all types of non-coring or coring drill traces. Our drill bits are used for well drilling, mining and construction contractors. Our drill bit has been tested and verified by time, with wear resistance and fast drilling speed. Different drill bits can be customized according to different rock formations. The engineering time is greatly shortened, and the maximum performance is exerted in the operation during drilling. Our products are durable and reliable. Our products are the preferred drill bits for drilling engineers in many countries because of our precise design and efficient drilling during use.
