A detailed explanation of the core features of the 12.9-grade CNC Torx screw shank, screwdriver, blade, and matching tooling.
High-Strength Material
Made of alloy steel or tool steel, heat-treated to a hardness of 12.9, ensuring fracture resistance under high torque.
The precision hexagonal socket design and hexagonal head (T-shaped) perfectly fit the screw, preventing slippage and making it ideal for repetitive tightening in automated CNC equipment.
CNC Compatibility
The high concentricity and rigidity design compatibly accommodates the quick tool change systems of CNC machine tools, supporting high-speed cutting.
II. Core Features of the Screwdriver and Blade
Thread Forming Accuracy
The carbide blades are precision-ground to ensure thread tolerances of ISO 6H/6g.
Multiple Size Compatibility
Modular toolholders enable quick blade changes, covering sizes from M2.5 to M8.
Wear-Resistant Coating
TiAlN-coated blades extend blade life by 3-5 times, making them suitable for efficient machining of stainless steel and titanium alloys.
III. Functional Details of Supporting Tools
Specifications Applications
M2.5: Micro screws for electronic products
M4: Home appliances/automotive parts
M8: Heavy machinery components
IV. Synergistic Advantages
Efficient Processing: The CNC toolholder + gun cutter combination enables one-stop screw hole drilling and tapping.
Life Management: The insert can be indexed 4-6 times, reducing the cost per blade by 40%.
The core of this tool series is the combination of materials, geometric design, and CNC adaptability to achieve high-precision and efficient screw processing, making it particularly suitable for high-volume precision manufacturing.
