Product Overview

Our uncoated 3-flute step forming cutter features precision-ground tungsten carbide edges optimized for high-speed machining of non-ferrous materials. Designed without coatings to maintain maximum sharpness, this tool delivers exceptional surface finishes (Ra 0.2-0.8 μm) while preventing material adhesion in aluminum, copper, and plastic applications. The unique 3-flute step geometry enables simultaneous multi-diameter machining, reducing cycle times by eliminating tool changes.

Key Features
  • Uncoated Carbide Construction
    • Micro-grain tungsten carbide (0.5-0.8μm, 10% cobalt)
    • No coating = sharper cutting edges vs. AlTiN/TiN tools
    • Mirror-polished flutes reduce friction
  • Optimized 3-Flute Design
    • Balanced chip evacuation for stringy materials
    • 40° helix angle reduces cutting forces
    • Alternate tooth spacing minimizes vibration
  • Step Forming Geometry
    • Custom step heights (0.5-20mm, ±0.01mm tolerance)
    • 90°/120° shoulder angles available
    • Center-cutting capable for plunge milling
  • High-Speed Performance
    • Stable at 15,000-30,000 RPM (diameter-dependent)
    • Dry machining compatible
Performance Advantages
  • 50% Longer Tool Life vs HSS in aluminum alloys
  • 30% Higher Feed Rates achievable vs coated carbide
  • Burr-Free Edges reduce secondary finishing
  • OEM/ODM Flexibility - fully customizable geometries
Typical Applications
  • Aerospace
    • Lightweight structural pockets in 6061-T6
    • Cooling channel profiling in C17200 copper
  • Electronics
    • Heat sink fin machining
    • Connector slot milling
  • Automotive
    • Aluminum housing stepped bores
    • Composite trim components
  • Medical
    • Implant contouring in Ti-6Al-4V (uncoated version)
    • Polymer device housings
