Precision Uncoated 3-Flute Step Forming Cutter

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) with mirror-polished flutes to reduce friction
Optimized 3-Flute Design - 40° helix angle reduces cutting forces with alternate tooth spacing to minimize vibration
Step Forming Geometry - Custom step heights (0.5-20mm, ±0.01mm tolerance) with 90°/120° shoulder angles available
High-Speed Performance - Stable at 15,000-30,000 RPM (diameter-dependent) with dry machining compatibility

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 with fully customizable geometries

Industrial 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, polymer device housings
