6mm 4-Flute R1.5mm Uncoated Solid Carbide Corner Radius End Millfor Aluminium & Non-Ferrous Fillet Milling

Uncoated (bright-polished) corner radius end mills are optimised for aluminium alloys, copper, brass, and graphite — any material where coatings cause adhesion. The corner radius produces clean fillet radii in pockets and profiles without a separate deburring step. Polished flute surfaces prevent built-up edge (BUE) that would otherwise ridge the fillet radius in soft metals. 4 flutes maximise feed rate and achieve Ra < 0.8µm in aluminium at high spindle speeds. Radius options from R0.2–R2.5mm cover all standard fillet requirements.

Large fillet for structural and automotive components requiring R1.5 corners

  • Single-pass production of R1.5mm fillet features
  • Eliminates interpolation entry required for ball-nose on same radius
  • Lower vibration tendency vs ball nose on shallow 3D surfaces
  • Preferred for automotive and aerospace structural pocket corners
Radius Selection Tip: R1.5mm corner radius end mills excel where a ball nose would need to interpolate along the corner arc at reduced feed. Here, the corner radius matches the required fillet exactly — one pass, precise radius, no interpolation error. Ideal for automotive die corner features.

6mm Uncoated — Where This Tool Fits

  • Mould cavity pocket semi-finishing
  • Precision aerospace part profiling
  • Hydraulic manifold pocket corners
  • Small fixture and jig features
Machining Tip: ø6mm with corner radius provides the best size-to-stiffness ratio for die and mould work. In aluminium alloy, the corner radius allows 3–5×D axial depth without the micro-chipping that limits sharp-corner tools. Ideal for continuous shoulder milling passes.

Uncoated on Corner Radius Geometry

  • Mirror-polished corner geometry — zero aluminium adhesion on curved arc
  • Eliminates BUE that would deform fillet radius in soft alloys
  • Clean fillet radii in aluminium — no post-milling deburring required
  • Works in copper, brass, graphite, and CFRP composite materials
  • Use with air blast or light oil mist at 10,000–30,000 RPM
