YOUCUT 3 Flute Carbide End Mill for Aluminum

Model: D3-9-D3-50L-3T
Applications: High-speed slotting, contouring, and finishing of aluminum alloys (6061, 7075), brass, copper, and non-ferrous composites.

 

Key Features

 Optimized for Aluminum

• 3-Flute Design: Balances chip evacuation and cutting speed, ideal for soft, gummy materials.

• Polished Flutes & Rake Face: Reduces material adhesion (BUE) for consistent surface finish (Ra ≤0.8μm).

 High-Speed Ready

• Micro-Grain Carbide Substrate: Supports spindle speeds up to 30,000 RPM without edge chipping.

• Uncoated Design: Maximizes sharpness for aluminum, avoiding coating-related edge rounding.

 Enhanced Stability

• Reinforced Neck Geometry: Minimizes deflection in deep pockets (up to 5×D cutting depth).

• Dynamic Balance: Precision ground for vibration-free machining of thin-wall parts.

 

Technical Specifications

• Diameter Range: 2mm-16mm (Standard), Custom up to 20mm

• Flute Length: 3×D / 5×D / 8×D (Deep cavity optimized)

• Shank Diameter: 3mm-12.7mm (1/8"-1/2")

• Coating: Uncoated (Recommended for Aluminum) / Optional TiAlN (For mixed-material use)

• Tolerance: ±0.005mm (Precision ground for tight tolerances)

• Max RPM: 30,000 (Consult speed/feed charts for optimal parameters)

 

Performance Benefits

 Chip Evacuation Master: Wide flute gullets prevent chip clogging in high-volume machining.
 Cost-Efficient: 3x longer tool life vs. HSS end mills in aluminum.
 Versatile: Suitable for dry or wet machining, from roughing to mirror finishing.

 

Ideal Use Cases

• Aerospace: Lightweight aluminum structural component milling.

• Automotive: High-speed machining of EV battery housings.

• Electronics: Precision cooling fin milling for LED heat sinks.

• Prototyping: Rapid material removal in 3D-printed aluminum parts.

• Consumer Goods: Smooth finishing of aluminum smartphone cases.

 

Safety & Maintenance

Use ER Collets with minimal runout (<0.005mm) for optimal performance.
Avoid excessive feed rates: Use chip load calculators to prevent tool breakage.
Clean with non-corrosive solvents; store in anti-rust sleeves.

 

Packaging & Support

• Professional Kit: Individually packed in anti-tarnish foam + labeled plastic tube.

• Bulk Orders: 10 pcs/box with custom branding.

• Warranty: 6-month breakage replacement (Excludes improper use).

• Free Resources: Aluminum Machining Handbook + Chip Load Calculator App.
