PDC ( Polycrystalline Diamond Composite ) are made by combining some layers of polycrystalline diamonds with a layer of cemented carbide liner at high temperature and high pressure. PDCs are among the most rigid of all diamond tool materials.

1. Choosing the quality materials
Core drill bit selected high-quality PDC, with the features of high wear resistance,
high drilling efficiency, and quality constant.
2. High efficiency and low damage
Equip with advanced CNC machining equipment, increased the drill bit efficiency,
reduced the accidental damage.
3. Low energy consumption
The formation is broken by cutting, scraping and shearing, which reduces the construction labour intensity.
4. High-speed rotation
Normal work could be proceeding under the status from 0-1000rpm.
