Heat Treated Round Retract Button Bit T45 76mm for Mining and Construction
Retrac button bits are manufactured from high-quality steel and cemented carbide, ensuring extended service life. The retrac design minimizes impact energy loss during transmission while advanced button fixing technology provides uniform fixing force to prevent button loosening. These drill bits maintain borehole perpendicularity, concentrating impact energy on the rock for improved drilling efficiency.
