10 5/8" DHV537GT

10 5/8" DHV537GT

• Product profile

1. With high-strength and high-wear-resistance carbide inserts which are advanced in  strength and wear-resistance.
2. With new journal bearing structure which greatly prolongs the service life of the bearing, and has the ability to withstand high drilling pressure and adapt to high rotational speed.

3. Adopt new flat sealing ring, more suitable for the working environment and the operating parameters of rock bit.

4. New type sealing structure make sealing performance and bearing matching, thus greatly improve the service life of drill bit.

• Cutting rows layout

4-4-4

• Applicable formation

Designed for water well drilling, low compressive strength, medium soft, such as hard shale, anhydrite, soft limestone, sandstone, dolomite with interlayer, etc.

• Lug Protection

The shirttail and the lug back are protected by welded wear-resisting carbide inserts.
