Tungsten Carbide Ball Tooth Drill Head Selection

In the tungsten carbide ball tooth drill head selection, there are several shapes: hemispherical gear, bevel gear, parabolic tooth, wedge-shaped teeth.

Hemisphere teeth enough hydraulic rock drill impact energy, energyutilization is high, the effect of rock breaking, extremely resistant alloy teeth. Cone-toothed alloy ball gear is easy to chisel into the rock drilling rate higher impact energy (wind pressure of wind power rock drill, hydraulic rock drill performance change) bevel gear work more effectively, but poor abrasion resistance. Parabolic ball gear between bevel gear and hemispheric is of foreign alloy plant or joint-venture factory production and use.

The wedge-shaped ball gear is suitable for hard and abrasive rock.
