YOUCUT 3 Flutes Extra Long Carbide End Mill

Model: D4-16-75-3F
Applications: High-speed deep cavity machining, thin-wall milling, and precision finishing of aluminum alloys (6061, 7075), brass, plastics, and non-ferrous composites.

 

Key Features

 Deep Cavity Expertise

• 8×D Neck Length: Enables machining depths up to 64mm (e.g., 8mm tool diameter).

• Reinforced Tapered Neck: Minimizes deflection in deep pockets while maintaining rigidity.

 Optimized for Aluminum

• 3-Flute Design: Wide chip gullets maximize chip evacuation, preventing clogging in high-volume aluminum machining.

• Polished Flutes & Rake Face: Nano-polished surfaces reduce material adhesion (BUE) for Ra ≤0.8μm finishes.

 High-Speed Performance

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

• Uncoated Sharp Edges: Ideal for non-ferrous materials, ensuring maximum sharpness and minimal heat generation.

 

Technical Specifications

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

• Neck Length: 5×D / 8×D / 10×D (Customizable)

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

• Coating: Uncoated (Recommended for Aluminum) / Optional TiAlN (For mixed materials)

• Tolerance: ±0.005mm (Precision ground to aerospace standards)

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

 

Performance Benefits

 Stability in Deep Cuts: Anti-vibration geometry ensures smooth operation in thin-wall parts (e.g., <1mm wall thickness).
 Chip-Free Machining: Efficient chip evacuation prevents recutting and tool breakage.
 Cost-Efficient: 5x lifespan vs. HSS end mills in high-speed aluminum applications.

 

Ideal Use Cases

• Aerospace: Deep pocketing in titanium-aluminum hybrid fuselage components.

• Automotive: Machining EV battery cooling plate channels.

• Electronics: Precision slotting in copper-aluminum heat sinks.

• Consumer Goods: Smooth finishing of aluminum laptop casings.

• Medical: Complex 3D profiles in biocompatible aluminum implants.

 

Safety & Maintenance

Use High-Precision ER Collets (e.g., ER-32) to minimize runout (<0.003mm).
Avoid excessive radial engagement: Keep ≤30% tool diameter in deep cavities.
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 Guide + Vibration Analysis Software.
