3-Flute · Uncoated · Aluminium · Standard Reach
7mm 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.

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
