Impregnated Diamond Bit and Reaming Shell(PWL, HWL, NWL, BWL and TW Series)

Description of PWL HWL NWL BWL and TW series of diamond products:

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.We carries out design and customization as per different customers' demands to meet drilling demands at various levels.

Synthetic impregnated diamond bit: equivalent to a grinding wheel, diamond and matrix powder are made into a sintered body through powder metallurgy. When diamond is worn out or abraded, the matrix body is exposed synchronously. Therefore, a new sharp diamond exposes out of the matrix body again to keep the drilling bit cutting into rock at high speed.

Height of the impregnated layer refers to the height of the matrix body where the impregnated diamond bit crown contains diamond work layer. Our company can provide diamond bits with impregnated matrix height from 9mm to 20mm as per customers' demands. The regular matrix height is 12mm.

Shapes of drilling bits can be divided into drilling bits in standard, wedged and semicircle shapes; shapes of impregnated diamond bit waterway can be divided into standard, wedged and turbo type.
