3 Flute UType Carbide End Mill Precision Roughing Finishing for Aluminum 6061/7075

Introduction:

This 3-flute U-type carbide end mill is specially engineered for high-efficiency aluminum machining, combining roughing and finishing capabilities in a single tool. Designed for 6061 and 7075 aluminum alloys, its U-type flute geometry ensures superior chip evacuation, reduced cutting resistance, and exceptional surface finishes—eliminating the need for tool changes between operations. Ideal for high-speed CNC machining, this end mill maximizes productivity while maintaining precision.

Features:

✔ 3-Flute U-Type Design – Optimized for high-speed aluminum machining with excellent chip flow and reduced built-up edge (BUE).

✔ Roughing & Finishing in One Tool – Unique geometry allows aggressive material removal while achieving fine surface finishes (Ra ≤ 0.4μm).

✔ High-Performance Carbide Substrate – Ultra-fine grain carbide ensures long tool life and heat resistance in continuous machining.

✔ 38° Helix Angle – Balances cutting aggression and smoothness, minimizing vibration for stable performance.

✔ Nano-Coating Option (TiAlN/AlTiN) – Reduces friction and prevents aluminum adhesion for extended tool life.

✔ Precision Ground Cutting Edges – Ensures consistent accuracy (±0.01mm) and repeatability.

Advantages:

✅ 30% Faster Machining – Combines roughing and finishing, reducing cycle times.

✅ Superior Chip Evacuation – U-type flutes prevent chip clogging in deep pockets.

✅ Mirror-Like Finishes – Achieves fine surface quality without secondary operations.

✅ Reduced Tool Changes – Single-tool solution saves setup time and costs.

✅ Vibration Damping – Stable cutting performance even at 20,000+ RPM.

Applications:

Aerospace – Structural components, aircraft fittings

Automotive – Engine blocks, transmission housings

Electronics – Heat sinks, LED housings

General Machining – Mold cavities, prototypes
