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.
