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.
- ✔ 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
- 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
- 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)
