Key Features & Benefits

11-Degree Cutting Angle for Powerful Penetration

The 11-degree tapered tooth angle enables high-speed drilling with deeper rock penetration. While steeper angles can increase vibration in shorter bits, the long shank design mitigates this risk, preventing wobbling and ensuring precise hole alignment.

Optimized 7-Tooth Cutting Head Design

Precisely engineered to balance drilling speed and tool lifespan. With fewer teeth than 8-tooth alternatives, each tooth applies greater cutting force for faster rock breakage and improved efficiency.

Long Shank Design for Stable Deep Hole Drilling

The extended shank, crafted from high-strength 42CrMo alloy steel with uniform cross-section, resists bending under heavy torque and lateral stress. This maintains alignment even in deviated drilling paths for reliable deep hole operations.
