6mm 4-Flute R0.5mm Uncoated Solid Carbide Corner Radius End Millfor Aluminium & Non-Ferrous Fillet Milling

Name: 6mm 4-Flute R0.5mm Uncoated Corner Radius End Mill for Aluminium
Brand: Solid Carbide Direct
SKU: SCD-CREM-UNCOATED-4F-D6-R05-L30
Price: 32.53 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.

R0.5mm Corner Geometry

Industry standard fillet — most common CNC pocket and shoulder radius

▸Longest tool life in class for shoulder milling and pocketing
▸Matches ISO standard pocket corner specification R0.5mm
▸Reduces cutting forces by ~20% vs sharp corner in hardened steel
▸Available in full standard size range including long-reach variants

Radius Selection Tip: R0.5mm is the most universal specification. In aluminium alloy, it provides the best balance of fillet feature accuracy, tool life, and chatter resistance. Recommended for all new mould base and structural component programmes unless design specifically requires R < 0.5mm.

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
