U Groove Aluminum End Mill h6 45 Degree Helix End Mills 12mm Ultra Long Life

Ultra Long Life Aluminum Cutter 45° Helix U Groove with Diamond Like Coating

Introduction:

Our premium 45° helix U-groove carbide end mill revolutionizes aluminum machining with its groundbreaking Diamond-Like Carbon (DLC) coating technology. Specifically engineered for high-volume production environments, this cutter delivers unparalleled tool life and exceptional surface finishes in all aluminum alloys, from soft 6061 to challenging 7075. The unique combination of 45° helix angle and optimized U-groove flute geometry ensures vibration-free performance at extreme cutting speeds.

Features:

• • • Advanced DLC Coating:

      • 3X harder than standard TiN coatings

      • Ultra-low friction coefficient (0.1-0.2)

      • Virtually eliminates aluminum adhesion

• • • Optimized 45° Helix Design:

      • Perfect balance between shear cutting action and chip evacuation

      • Reduces cutting forces by 25% compared to 30° helix tools

      • Enables higher feed rates without chatter

• • • Proprietary U-Groove Technology:

      • 20% larger chip pockets than conventional end mills

      • Specialized edge preparation prevents built-up edge (BUE)

      • Mirror-polished flute surfaces for smooth chip flow

Advantages:

✓ 5-8X Longer Tool Life vs. standard coated end mills

✓ Achieves Ra 0.3μm Surface Finish in final passes

✓ Stable at 25,000+ RPM for high-speed machining

✓ 30% Higher MRR (Material Removal Rate) capability

✓ Consistent Performance across dry/mist machining conditions

Applications:

Aerospace: Structural components, wing ribs, bulkheads

Automotive: EV battery housings, transmission cases

Electronics: 5G heat sinks, LED housings

Racing: Lightweight chassis components

General CNC: High-volume aluminum parts production
