Stainless Steel Specific Taps
1. Helical Flute Design:
The unique helical flute structure enables efficient chip evacuation, reduces cutting resistance, and prevents chip clogging. This design is particularly suited for machining work-hardening, high-viscosity materials (e.g., stainless steel, chromium steel, molybdenum steel) in blind-hole workpieces.
2. Optimized Cutting Angles:
The rake angle and relief angle are engineered for stainless steel characteristics, balancing sharpness and durability to extend tool life under continuous machining loads.
3. Anti-Adhesion Properties:
A specialized surface treatment minimizes material adhesion during cutting, effectively preventing built-up edge (BUE) formation and ensuring stable threading performance.
4. High-Precision Threading:
Designed for high-precision internal threading applications, especially in deep-hole or blind-hole scenarios, with ground thread profiles achieving ISO 2 accuracy standards.
TYPICAL APPLICATION SCENARIOS
Industries: Petrochemical, medical devices, food machinery, aerospace (stainless steel components).
Materials: Austenitic (304/316), martensitic (420) stainless steel, and other tough alloys.
Operations: Blind/through-hole threading requiring smooth finishes and low heat generation.
Machines: Low-speed, high-torque machines or CNC centers (cutting fluid recommended).
