2013 Hot Rock Bit Insert for Mining or Coalfield Drilling

ABOUT US
Zhengzhou LD Diamond products Co., is located in birth land of Shaolin Kungfu— Zhengzhou, China, is a high tech enterprise that specializes in the research, manufacture and marketing of diamond products, has taken the lead in mining drilling, metal cutting and grinding processes 3 big fields.

ABOUT PRODUCTS
Polycrystalline Diamond Compact (PDC), is a super hard composite material synthesized a layer of selected diamond particals and bonded to a tungsten carbide substrate. Combining the properties of both super hardness and abrasion resistance of diamond with outstanding strength and toughness of tungsten carbide, PDC has been widely used in mechanical industry, oil well drilling, geological prospecting drilling and coal mine drilling.
The standard shape is cylinder, we can also supply the PDC cutters in all kinds of shapes (square, rectangle, triangle, sector, etc. )with diameter from 4 to 25mm, PDC layer from 0.3 to 3mm, the total height from 1.0 to 25mm. Other size and shapes could be made as your requirement.

ADVANTAGES
1. Selected higher quality diamond powder, improved the sintering technique, and enhanced the bond combination strength between diamond grains.
2. Improved the inner structure of the sintered cavity, the pressure and temperature become more balance, which ensure the cutter has more stable performance.
3. Adopted a new type of carbide, which improved the weld strength.
4. Optimized the designation of joint face, which reduced the residual stress.
5. Increased the rate of penetration in highly demanding drilling applications effectively

Feature:
1. The joint face of PCD layer and the tungsten carbide is designed with claws, which ensure the combination is more firm and the cutter has higher impact resistance.

2. Microstructure with complete C-C bond combination is characterized between the grains of the diamond in PCD layer, which ensure the high strength, hardness and abrasion resistance of diamond layer.

3. The new sharp cutting surface will keep cutting in the drilling process.
