Spherical and Conical Tungsten Carbide Button

Comparing with other similar products tungsten carbide button is more suitable for using in high pressure and speed drilling because of its good wearing resistance. According to relevant data, tungsten carbide button drill bits have 4~5 times longer lifespan than other drill bits have same diameter such as split, cross and treble, etc, which not only saves working hours and labor force, but also accelerate the project.

Spherical and conical tungsten carbide button is the most common types. There is a hole on the bottom of spherical button for inlay system impact class drill, drill bits and DTH conical drill bits for very hard rocks. Conical button has similar structure, except taper and chamfer has some differences. Conical button is suitable for medium hard rock formations because conical button is broken easily. In addition, the allowable deviation of arc radius is between 0-0.50mm, chamfer tolerance is ±0.20mm-±0.40mm.
