Product Overview
Our 5-tooth, 34mm diameter ball-shaped drill bit is engineered for medium-duty rock drilling applications in mixed formations. With its compact 64mm height and 11° tapered design, this drill bit delivers targeted rock-breaking performance while maintaining excellent drilling accuracy. Ideal for small-scale mining operations, construction anchoring, and geotechnical sampling, this tool ensures consistent hole quality, reduces operator fatigue, and provides extended service life. Perfectly suited for use with handheld or lightweight drilling rigs.
Key Features & Benefits
Five-Tooth Layout: Balanced force distribution enables fast and stable drilling performance
11° Taper Angle: Provides excellent centering capability and superior drilling accuracy
64mm Compact Height: Designed for operation in confined spaces and limited clearance applications
Advanced Material Construction:
Wear-Resistant Buttons: YG10C tungsten carbide buttons feature high hardness (HRA ≥88) and exceptional impact toughness
Reinforced Steel Body: Heat-treated alloy steel through quenching and tempering enhances bending strength and prevents breakage in hard rock layers
Corrosion-Resistant Coating: Galvanized surface protection extends service life by 25% compared to uncoated drill bits in mine water or damp conditions
