Product Description

Product Description

As one of the main manufacturers for diamond geological tools in China, our company has excellent   product  design,   international  advanced   pressure-less  sintering   process,  fully imported raw material, precise processing equipment, senior expert in powder metallurgy field and strict quality control. The company carries out design and customization as per different customers' demands to meet drilling demands at various levels.

Waterway Shape List
Standard W Profile : standard design,suitable for a wide range of formations
Flat  Profile :  increased water flow;  Improving cutting speed; Suitable for rock boken and high abrasive stratum
Turbo Profile: Suitable for high-speed cutting and drilling to improve the pressure on the working face; Suitable for hard formations

Waterhole Type List
FD Type: the modified design reduces the scouring of the core by water and improves the core extraction rate;Suitable for fractured or granular rock formations.
Elongated  FD  type:  Elongated FD water hole has better effect than round water hole,and it is more effective to prevent water plugging and drilling burning.
Deep groove Type: the design combines the advantages of standardW profile surface and bottom spray lip surface, the process is simple and reliable;Suitable for broken or hard formations
Vortex Type: I mproves working efficiency by reducing the interaction time between the hole and the core; Suitable for soft to medium hard  formations.

Matrix Shapes
The bit water way shapes can be customized as standard W profile, wedged profile and turbo profile bit, etc.

1.Recommended diamond size
The soft stratum uses the large grain diamond 15 grains/carat;
Medium grain diamond 20-30 grains/carat for medium and hard strata;
Hard formations use 40-60 grains of small diamond/carat.
2. Reaming Shell- Impregnated diamond bit types
Artificial diamond insert reamer: this product uses high grade artificial diamond and polycrystalline strip, the matrix wear resistance is high,the water performance is good, therefore the service life is long, the efficiency is high.
Natural diamonds etreaming shell (Heavy duty): this product is made of high quality and selected natural diamond and polycrystalline, with high efficiency of water transfer performance, durability and satisfactory drilling efficiency .
Mixed reaming shell (Super heavy duty): natural and artificial diamonds are mixed in the tire body during the production process to extend the service life and achieve the best time of reaming and drilling.
