14mm 4-Flute R1mm 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.

R1mm Corner Geometry

General-purpose fillet milling — strongest corner geometry for heavy passes

  • ▸Maximum radial support on cutting edge during heavy DOC passes
  • ▸Ideal for semi-finish passes before a smaller-radius finishing pass
  • ▸Produces clean R1mm fillets in one pass — no secondary operation
  • ▸Recommended for die cast tooling, injection mould cores, and structural pockets
Radius Selection Tip: R1mm provides the highest edge strength of commonly used radii. In aluminium alloy, DOC can be increased 20–30% over R0.5mm without chatter. Use for semi-finish passes that must leave a consistent stock allowance before a ball-nose finish.

ø14mm Applications

14mm Uncoated — Where This Tool Fits

  • ▸Large die base and plate shoulder milling
  • ▸Heavy-duty structural pocket machining
  • ▸Pressure vessel and flange features
  • ▸Mining and energy equipment pockets
Machining Tip: ø14mm corner radius end mills generate high cutting forces. Minimum spindle power 15 kW in aluminium alloy. The corner radius at this scale carries a significant load — ensure machine toolpath generates consistent chip load using adaptive CAM strategies.

Coating Performance

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
