6mm 4-Flute R2mm Uncoated Solid Carbide Corner Radius End Millfor Aluminium & Non-Ferrous Fillet Milling

Name: 6mm 4-Flute R2mm Uncoated Corner Radius End Mill for Aluminium
Brand: Solid Carbide Direct
SKU: SCD-CREM-UNCOATED-4F-D6-R2-L15
Price: 16.27 USD
Availability: InStock

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.

R2mm Corner Geometry

Heavy-corner fillet for energy, marine, and structural components

▸Produces R2mm fillets without interpolation — direct plunge-to-shoulder possible
▸Widely used in wind turbine nacelle components and frame pockets
▸Reduces stress concentration on R2mm structural fillets vs machined-in ball nose
▸Long-reach variants for deep pocket access (L1 up to 150mm)

Radius Selection Tip: R2mm at this tool diameter means a significant portion of the cutting edge is curved. In aluminium alloy, reduce feed rate 10–15% vs R1mm to maintain consistent chip load across the radius. Trochoidal milling strategies work well for R2mm pocketing.

ø6mm Applications

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.

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
