PDC Drag bit is more wear-resistant and has high impact toughness.
1. It is suitable for medium hard rock drilling, such as geological drilling, water well drilling, mining, etc
2. Size range: 65mm, 75mm, 94mm, 113mm, 133mm, 153mm, 200mm, 250 mm, 350 mm etc.
polycrystalline diamond compact
PDC cutters are made of fine diamond powder and hard tungsten carbide under high temperature and pressure. It has the same high wear resistance as diamond and the impact resistance of tungsten carbide, making it the best material for drill cutters.
