Thin 304 stainless steel sheets (0.5–3mm) pose threading challenges due to work hardening and heat generation. The M35 combination drill and tap bit conquers these issues with aerospace-grade precision and thermal management.
Cutting-Edge Technologies
Variable Helix Tapping Flutes: 45°/35° alternating angles prevent harmonic chatter.
Cryogenically Treated M35 HSS: Enhances wear resistance by 50% vs. standard M2.
Through-Hole Optimization: 10° exit angle prevents burrs on sheet metal underside.
Certified Results
Ra 0.8µm Thread Finish: Meets ASME B1.13M Class 2A.
0.01mm Pitch Diameter Deviation: Over 300 holes in 1mm 304SS.
600°C Thermal Stability: Verified in jet engine bracket production.
Medical Device Manufacturing Case
Creating M3 threads in 2mm stainless steel biopsy tools:
Zero Distortion: Critical for laser-welded assemblies.
3,000 RPM Dry Machining: Eliminated coolant contamination risks.
FDA-Compliant Surfaces: Achieved via mirror-polished flutes.
Specifications
Coating: TiAlCrN for corrosion-prone environments
Length of flute: 13.5mm for M3
Tolerance: ±0.015mm on hole position
Trusted by aerospace OEMs and surgical instrument makers worldwide.
