Our tapered button bit has taper hole design for easy matching with tapered drill rods. The distributed spherical carbide teeth produce powerful impact crushing force, featuring high drilling efficiency and outstanding wear resistance, suitable for hard rock, granite and highly abrasive rock layers. Each carbide ball tooth is firmly welded by professional high-temperature brazing process, effectively preventing tooth loss under frequent percussive drilling. Reasonable flushing grooves ensure smooth slag discharge, forming straight and smooth drill holes. Widely used in mine tunneling, quarry exploitation, road construction and slope anchoring engineering. With precise dimensional control and stable product quality, it greatly reduces replacement frequency and cuts overall construction drilling costs for geotechnical projects.
