64mm Tapter Reaming Bit Wear Resistant Dome Button Bits For Drifting / Tunnelling
Under any geological conditions, our reaming drill bits make drilling operations more efficient and labor-saving. The bits feature a proprietary carbide drill stem design for deeper and faster drilling. The body is made of precision-hardened nickel-molybdenum steel with a compound curve shape, enabling smoother cutting and easy chip removal.
The reaming drill bits boast an optimized head length, heavily supported carbide button structure, and deep flutes for excellent flushing and powerful cutting performance. They reliably adapt to various rock conditions and allow flexible adjustment of the borehole diameter after reaching a certain depth, enhancing project adaptability.
