Detailed Product Description
DPF Series are our newest products. Based on adoption of a series of new technology and high quality raw materials, impact resistance and thermal stability of DPF Series improve a lot, and rate of penetration increases while drilling hard rock. DPF Series have achieved outstanding drilling performance and is highly estimated by customers.
Characteristics
- Higher grade and purer diamond powder, in which impurity content decreases vastly, is chosen as raw material to increase bonding strength among diamond.
- Grit mixture ratio of diamond powder and sintering technics are improved which increase rate of penetration while drilling in hard rock.
- Shallow slots in length and breadth distribute homogeneously on the top of tungsten carbide substrate. This kind of interface improves stress distribution and raises impact resistance and reliability.
- Thermal stability reaches 750.
- Improved structure of sintering cavity makes that temperature and press distribute homogeneously during the sintering process, and assures stable performance of PDC cutters.
