17 1/2"steel tooth tricone drill bit/oilfield mill tooth bit/ore mining dril bit

1.Cutting Structure

The durability of premium tungsten carbide inserts isimproved with new formulas and new techniques for insert bit.

2.Gauge Structure

Multiple gauge protection with gauge trimmers on heeland gauge inserts on the gauge surface of the cone, tungsten carbide inserts andhardfacing on the shirttail increases gauge holding capability and bearinglife.

3.Bearing Structure

High precision bearing with two thrust faces. Ballslock the cone.Hardface heard bearing surface. Cone bearing inlaid withfriction-reducing alloy and then silver-plated. Abrasion resistance and seizureresistance of the bearing are improved and suitable for high rotaryspeed.

Advantage

1.High-strength, high flexibility, high temperature, high wear resistance.
2. High-precision metal seal.
3. Locking roller ball, to adapt to high-speed.
4. The use of high strength high toughness carbide teeth,
5. Hours in the rotary cone bit with the impact, crushing and shearing the role of broken rock.
6. Cone bit to adapt to the soft, medium and hard of various strata.
7. Reasonable price and long working life.
