Tungsten Carbide Insert Bits
There are two sealing methods,sealed with O shape rubber rings or sealed with metal rings.The former adapts to conventional drill holes, the latter adapts to drill holes with high temperature and high speed.
Adopting friction balls to fasten cones, safe and reliable.
Buildup welding of wearing-resistant alloy at sliding surfaces of the head bearings to improve bearing capacity.
Inlay welding of copper alloy and silver-plated at sliding surfaces of cone bearings to strengthen self-lubricating effects,and improve anti-snapping ability.
