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.

R2.5mm Corner Geometry

Maximum standard corner radius — structural fillet finishing and heavy pocketing

▸Largest standard corner radius for high-load structural pockets
▸One tool for both side wall and corner fillet in a single pass
▸Reduces fillet machining time vs interpolated ball-nose strategy
▸Suitable for oil & gas, aerospace, and heavy equipment components

Radius Selection Tip: R2.5mm requires careful feeds and speeds management — the curved cutting edge geometry changes effective rake angle significantly across the arc. In aluminium alloy, use conservative feed (60–70% of square end mill equivalent) until material behaviour is confirmed.

ø16mm Applications

16mm 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: ø16mm 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
