High-Hardness Alloy 32mm x 65mm Tapered Button Bit for Small-Scale Mine Slope Support
This Henglong 32mm x 65mm tapered button drill bit is engineered with high-quality, high-hardness tungsten carbide alloy specifically for the demanding requirements of small-scale mining and slope support drilling. The precisely machined button inserts and tapered shank design ensure perfect compatibility with most lightweight rock drills.

Key Features
Excellent Wear Resistance: The high-hardness alloy matrix resists abrasion from rough rock formations and reduces tool replacement downtime in slope reinforcement projects.
Stable Drilling Accuracy: The 32mm drilling diameter and 65mm working length ensure consistent hole diameter required for anchor bolt installation, which is crucial for maintaining the structural integrity of small mine slopes.
Impact Resistance: The heat-treated drill bit body and reinforced button welding structure can withstand intermittent impact loads, preventing premature chipping or breakage in mixed rock and soil layers commonly found in mine slopes.
