Product Introduction

Xinhong matched drill bits for hollow anchor bolts adopt high-hardness tungsten carbide material, featuring wear resistance, impact resistance and high structural stability. Suitable for complex strata such as soft soil, rock and broken layers. The professional hollow design ensures smooth slag discharge and uniform grouting, effectively preventing hole blockage and collapse. Integrated precision molding guarantees high drilling accuracy and flat hole walls, greatly reducing drilling resistance and improving construction efficiency. Full specifications perfectly match our hollow anchor bolts with no on-site modification required. It effectively lowers replacement frequency and project cost, serving tunnels, mines, slopes and foundation pit anchoring projects as a durable and efficient supporting accessory.
