Drill Bits

Coring Drill Bits

Products varied, spec comprehensive, both rigid body type and matrix type, cutting elements include column awl glomerocryst, triangle glomerocryst, and diamond compact and natural diamond.

Drill bit with advanced design, reasonable structure, superior process, the longestsingle footage has more than 200m. The practice has proved that it is one of the essentially guarantee of choosing good core with it's high efficiency and low cost.

Diamond Drill Bits

Diamond Drill Bits of synthetic material made of polycrystalline diamond our company sold for the use of oilfield drilling products are in strict compliance with API SPEC 7 quality standard.

All of the products are reliable and superior in performance, and have been selling well at home and abroad.

Various different types of drilling bits can suit for drilling extremely soft to the hardware formations of various types of conventional drilling operations, lateral directional well drilling operations, coring drilling operations. And for users we can provide various types of diamond bits for comprehensive drilling, lateral drilling and whipstocking bits, various reaming bits and coring bits;

Meanwhile, we also would like to manufacture different types of drilling bits according to the special requirements of customers. Nominal diameter (in): 4” ~ 17 1/2” Formation: from extremely soft to Medium Hard API REG. pin size (in): 2 3/8”, 2 7/8”, 3 1/2”, 4 1/2”, 6 5/8”.

Drag Bits

Type: Chevron and Step type. Wings: 2, 3 and 4 wings. Size: 2 7/8" to 24" Thread: 2 3/8, 3 1/2, 4 1/2, 5 1/2, 6 5/8 API Reg. Pin. Drag bit are manufactured from forged high quality alloy steel and premium tungsten carbide insert, plus state of art welding technology and multiple precision heat-treatment to provide highest penetration rate and longest lifespan at roughest condition.

Standard: API SPEC 7 standard.

Roller Cone Bits

There are rich and diverse roller bits to meet different requirements of formations and rotary speeds. The sizes of the gage diameter and the types of bit are strictly designed in accordance with the standards API Spec.7. There are not only rubber sealed bearing bits but also metal face sealed bearing bits, and all bits are lubricated by new type of wear resistant grease that can sustain high temperature up to 250°C. The surfaces of main or key parts are hardfaced and treated with friction reducing technology. They can enhance gage protection and prolong the life of bit. Center nozzle is equipped for bits of larger sizes.
