Wholesale 98mm PDC Drag Bit 3 Blades For Hard Rock Drilling Water Well in the stock from China supplier.
-
- With 3 blades
- Plane PDC cutter
- threading inside
- OEM orders are welcome
- 3, 4, 5 or 6 wings are available
- DC bit/ PDC concave drill bit/ PDC arc pillar bit/ PDC blade bit /PDC drag bit /PDC core drill bit/ PDC core drill bit
- Diameter: 60, 65, 75, 94, 113, 133, 153 and 190mm
- Used for geology exploration hole, gas drainage hole and emissions hole
- PDC bit consist of PDC cutter brazed to matrix or steel body
- The PDC cutter has high hardness, abrasion resistance and toughness, provides a cutting structure for the rock formations that respond well to failure by shearing and wears by micro-chipping
- Compare to tungsten carbide bit, cone bit, diamond impregnated bit, the PDC bit has increased efficiency and longer lifespan
- Applied to drilling soft and medium hard formation
- Product description:
- PDC non-core bit mainly used for drilling soft and medium formation and used for the purpose of geology, coalfield, metallurgy, building, mining, projectsurvey, rail, bridges and housing
- Application: used to penetrate the degassing hole, drain hole and grouting hole of coal mine or for the purpose of geology, coalfield, metallurgy, building, mining, project survey, rail, bridges and housing
- Introduction of PDC (polycrystalline diamond compact)
- PDC is made of diamond micro-powder and hard tungsten carbide under high temperature and high pressure
- It possess of high wear resistance like diamond, at the same time the impact resistance like tungsten carbide and that’s made it the best material as a drill bit cutter
- Reinforced PDC has higher dense diamond powder, claw tungsten carbide substrate made the two layers solid as whole one
- So, the reinforced PDC of supper wear resistance, longer service lifespan and high-efficiency
- Characteristics: compared with the others, this one has a higher abradability and wide range of application (rock formation application)
