9 1/2" SHV547GXT

9 1/2" SHV547GXT

• Product profile

1. Adopt high strength and high wear resistance carbide teeth, enhanced the intensity of the teeth and abrasion resistance.

2. Adopt new journal bearing structure, greatly extend the life of the bearing, has the ability to withstand high wob and adapt high rotation speed.

3. New fluorinated rubber sealing ring performance improvement, 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 shale, soft limestone, dolomite with interlayer, coal seam, etc.

• Lug Protection

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