Product detail:
| Applications: | ||||||
| ♦ | PDC drill bit is mainly used to drill Oil well, gas well, water well, etc. | |||||
| ♦ | We design and produce specifie PDC bit with good performance for each soft, medium and hard formation. | |||||
| ♦ | Clay stone/lignite/siltstone/sands: We design 3-5 blades with low density cutter placement,large slot. Low cost,high speed . | |||||
| ♦ | Mudstone: We have experience to design suitalbe blades shape and cutter direction to get high drill speed and stalbe drill. | |||||
| ♦ | Gravel/limestone/shale/clay stone/tuff: Round crown and reasonable cutter direction. Drill smoothly in good speed. | |||||
| Introduction of PDC drill bit: | ||||||
| ♦ | Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance. | |||||
| ♦ | Dedicated PDC cutter can improve the life and shield the risk of complex formation drill not passed. | |||||
| ♦ | Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa) | |||||
| ♦ | Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life | |||||
| ♦ | (no repair life up to 8300M/pc). | |||||
| ♦ | The unique parabolic crown-shaped design and tooth balance design keeps smooth drilling under high speed. | |||||
| ♦ | (Speeds up to 30~40m/h.) | |||||
| ♦ | The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth. | |||||
| ♦ | Authoritative API standard and ISO certification, quality and service will be better ensured. | |||||
