GP-4 Solid Carbide 4 Flute Flat End Mill

Sharp cutting edge and tool strength reasonable match,cutting process more light, longer tool life. Can achieve high efficiency cutting from ordinary steel to pre-hard steel. From roughing with high precision and high surface quality.

Recommended Materials

Steel
  • 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 GP-4 Solid Carbide 4 Flute Flat End Mill 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 steel.

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.
