Product Description

NWL Reinforced Bits and Reaming Shells

 

 

Diamond Bits 
1.  Different waterway shapes

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

3. Casing Shoes
Our company produces various specifications of diamond and carbide casing shoes, can be suitable for standard drilling or used for casing positioning in drilling. The casing has cut blocks on the front and outside of it. The inside is smooth, and the bore of the casing shoe is large enough for the drill bit and tool to pass through.
