6mm 3-Flute Uncoated Solid Carbide Square End Millfor Aluminium & Non-Ferrous Machining

The 3-flute uncoated variant strikes the balance between chip clearance (3 vs 4 flutes) and rigidity, making it ideal for profile milling, contouring, and finishing passes in aluminium and copper alloys. Three equally-spaced flutes produce better surface finish than 2-flute on ramping and helical interpolation entries. Polished bright finish prevents material adhesion. Recommended for 5-axis machining centres and high-speed spindles above 15,000 RPM.

Where This Tool Excels

6mm Uncoated 3F — Recommended Applications

  • ▸Die and mould fine detail features
  • ▸Aerospace precision component profiling
  • ▸Small hydraulic manifold pocketing
  • ▸Electronic enclosure and heat-sink machining
Machining Tip: ø6mm is the most common size for precision detail work. In aluminium alloy, use 3–5× diameter axial depth with 30–50% radial engagement. TIR < 0.005mm at the tool tip is critical for consistent tool life.

Coating Performance

Uncoated — Why It Works

  • ▸Bright polished finish — zero micro-adhesion on aluminium
  • ▸Eliminates built-up edge (BUE) in soft metals
  • ▸Superior chip evacuation at high spindle speeds
  • ▸Recommended with air blast or light oil mist
  • ▸Mirror surface finish on aluminium: Ra < 0.4µm achievable
