Trenchless Directional Drilling HDD PDC Back Ream | RFQ Sourcing Details

♦ 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 8300 M/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 American Petroleum Institute standard and ISO certification, quality and service will be better ensured .

Size can be customized as per your requirement. Feature & Benefits Types of PDC Bits 1. Matrix Body PDC Bits "Matrix" is a very hard, rather brittle composite material comprising tungsten carbide grains metallurgically bonded with a softer, tougher, metallic binder.

Matrix is desirable as a bit material, because its hardness is resistant to abrasion and erosion. lt is capable of withstanding relatively high compressive loads, but, compared with steel, has low resistance to impact loading. Matrix is relatively heterogeneous, because it is a composite material.

Because the size and placement of the particles of tungsten car
