3mm 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

3mm Uncoated 3F — Recommended Applications

  • ▸Micro-feature engraving and lettering
  • ▸Precision watch and instrument components
  • ▸Dental and medical device micro-milling
  • ▸PCB sub-assembly pocket features
Machining Tip: At ø3mm, spindle runout must be ≤ 0.003mm. Use a high-precision collet (ER collet accuracy class ≤ 5µm). Feed rate 0.01–0.04 mm/tooth in aluminium alloy; avoid sudden direction changes to prevent tip breakage.

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
