3mm 2-Flute Uncoated Solid Carbide Square End Millfor Aluminium & Non-Ferrous Machining

Uncoated (bright polished) solid carbide with mirror-finish flutes specifically engineered for aluminium and non-ferrous alloys. The absence of coating eliminates the micro-adhesion that causes built-up edge (BUE) on soft metals — cutting is cleaner, chips evacuate freely, and surface finish is superior. The 2-flute geometry provides large chip gullets for maximum swarf clearance at high spindle speeds (up to 30,000 RPM in aluminium). Use with air blast or light oil mist.

Where This Tool Excels

3mm Uncoated 2F — 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
