MAU U Shaped 3 Flute Flat End Mill For Aluminum

U-type 3-flute flat end mill is designed for aluminum and non-ferrous metal machining. Its large U-flute structure ensures fast chip evacuation and smooth cutting, ideal for slotting and side milling. Widely used in automotive, aerospace and precision parts manufacturing, it provides high efficiency, stable performance and excellent surface finish for heavy-duty CNC machining.

Recommended Materials

Aluminum
  • Ultra-fine grain solid carbide substrate
  • Advanced PVD coating for heat & wear resistance
  • Precision ground geometry, tight tolerances
  • Custom sizes & OEM manufacturing available

Product Description

The MAU U Shaped 3 Flute Flat End Mill For Aluminum is a high-performance solid carbide end mill engineered for precise, productive milling. Manufactured from premium ultra-fine grain tungsten carbide, it combines high hardness with the toughness needed for consistent, chatter-free cutting and a superior surface finish. It is optimized for machining aluminum.

Precision edge preparation and a carefully engineered helix angle reduce cutting forces and improve chip evacuation, allowing higher feed rates without sacrificing accuracy. An advanced PVD coating lowers friction and dissipates heat, extending tool life even in continuous production.

Key Features

  • Sub-micron grain tungsten carbide substrate for an ideal balance of hardness and toughness
  • Precision-ground cutting edges hold tight diametral tolerances for accurate, repeatable results
  • Optimized helix angle evacuates chips cleanly and reduces cutting forces
  • Advanced nano-coating lowers friction and resists heat for extended tool life

Applications

Ideal for CNC milling, slotting, profiling, contouring and finishing. MSU Tools also manufactures custom geometries, coatings and dimensions to suit your specific material and application — contact our engineering team to discuss your requirements.
