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

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.

• 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
• Precision Ground Cutting Edges - Ensures consistent accuracy (±0.01mm) and repeatability

• 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
