SDFTools LongForce Drill G Series – Specialized Cutting Tools for Mining Rock Bit Tooth Hole Machining
——Designed for high-precision, high-efficiency mining rock bit processing, addressing machining challenges in harsh working conditions

I. Product Overview

The SDFTools LongForce Drill G Series is specifically engineered for the mining rock bit industry, suitable for machining high-hardness alloy steels (e.g., 15MnNi4Mo) with surface hardness ranging from HRC38 to HRC45. The series primarily adopts a conical bottom design , combined with nano-composite coating technology and a unique groove structure, offering a high-precision, high-efficiency, and long-lasting solution for tooth hole machining.

II. Applications and Characteristics in the Mining Rock Bit Industry

1. Industry Background and Applications

Mining rock bits are critical components in mining equipment, widely used in open-pit mining, underground tunneling, and rock fragmentation. The machining quality of tooth holes directly impacts the wear resistance, impact resistance, and service life of rock bits, requiring extremely high precision and material performance.

2. Machining Challenges

• Extreme Material Hardness : Common materials (e.g., 15MnNi4Mo) reach HRC45 hardness. Traditional tools suffer from chipping and rapid wear, failing to meet efficiency demands.
• Complex Geometric Shapes : Tooth holes require high-precision assembly, where surface roughness and roundness deviations directly affect rock bit balance.
• Chip Breakage Difficulties : Chips from high-hardness materials are hard to break, risking tool entanglement and fractures.
• High-Load Conditions : Machining involves high-frequency impacts and high temperatures, demanding superior tool wear resistance and thermal stability.
• Compatibility with Aging Machine Tools : Many mining enterprises use 8+ year-old 5-axis machining centers with poor rigidity and low spindle power, increasing tool adaptability requirements.

3. Our Advantages

The SDFTools LongForce Drill G Series is optimized to address these challenges:

• Superior Adaptability : Designed for aging machine tools with low spindle accuracy and rigidity, ensuring stable machining.
