Description
Ultra-Hard Left-Hand Thread Mill | ALTiSiN Coated | Two-Row Teeth Precision
Engineered for machining hardened steels and exotic alloys, the SDF-P Series left-hand thread mill combines German carbide technology with Balzers ALTiSiN coating to deliver unmatched performance in high-stress applications:
Dual-Row Cutting Innovation
- First Row (Roughing): Short teeth remove 70% material rapidly with low cutting force
- Second Row (Finishing): Full-profile teeth achieve Ra0.8μm finish in HRC60+ dies
- Left-Hand Advantage: Reverse spindle rotation stabilizes deep cavity threading (Ideal for injection molds)
Industrial-Proven Performance
- Base Material: 0.4μm German tungsten carbide (ISO K30-K40 grade)
- Coating: BALZERS ALTiSiN (3μm | 3,500HV | 900°C oxidation resistance)
- Certified Precision: ZOLLER inspected ≤0.008mm runout (ISO 2768-m compliant)
- Speed & Feed: 80-120m/min in H13 tool steel | 0.03-0.05mm/tooth
Mission-Critical Applications
- Automotive molds (NAAMS standard M18-M36 left-hand threads)
- Aerospace titanium fasteners (NASM 8879 compliant)
- Medical device screws in 17-4PH stainless steel
