Aluminum U-Type Slot Cutter 3 Flute Solid Carbide Flat End Mill with Color Coating for CNC Router Milling

Our 3-flute U-type slot end mill is precision-engineered for high-speed aluminum machining, featuring a vibrant multi-layer color coating that reduces friction and prevents material adhesion. Designed with a flat nose geometry and optimized U-groove flute design, this solid carbide cutter delivers exceptional chip evacuation and mirror-like surface finishes in CNC routing and milling applications.

Ideal for aluminum alloys (6061, 7075), copper, and soft plastics, it outperforms standard end mills in tool life, cutting speed, and finish quality.

Key Features

3-Flute U-Groove Design - Balanced for efficient chip clearance in aluminum
Multi-Layer Color Coating (Rainbow PVD) - Reduces heat buildup and material adhesion
Flat Nose Geometry - Enables precise flat-bottom slotting and contouring
Ultra-Fine Grain Carbide - German-grade substrate for maximum durability
High Helix Angle (45°) - Improves surface finish and reduces cutting forces
Diameter Range - 4mm to 20mm with custom sizes available

Performance Advantages

✓ 50% Faster Machining - Optimized for high-RPM CNC routers (up to 30,000 RPM)

✓ Anti-BUE Design - Coating prevents aluminum buildup on cutting edges

✓ Superior Finish - Achieves Ra < 0.3μm (near-mirror quality)

✓ Extended Tool Life - 3X longer than uncoated tools in abrasive alloys

✓ Reduced Vibration - Stable cutting in deep slots and thin-wall machining

Typical Applications

Aluminum Slotting - U-grooves for frames, heat sinks, and enclosures
Aerospace Components - Lightweight structural parts
Signage & Decorative Engraving - Clean edges in soft metals
PCB Milling - Precision routing of aluminum substrates
Prototyping - Fast material removal in 6061/7075 aluminum

Why Choose This End Mill?

Proven in Industry - Trusted by aerospace and automotive manufacturers
Color-Coated Technology - Visual wear indicator (coating fade = resharpening time)
Custom Options - Special lengths, corner radii, or coatings (DLC, TiCN)
OEM Support - Private labeling and bulk discounts available

Ideal for CNC shops, aluminum fabricators, and high-volume production. Contact us for custom configurations or technical guidance!
