The GP-4 4 flute flat end mill is manufactured from premium micro-grain solid carbide and finished with a high-performance coating for reliable machining of hardened steels and cast iron. The short flute design increases rigidity and helps maintain tight tolerances and consistent surface quality.
| Item | Specification |
|---|---|
| Tool type | Solid carbide 4 flute flat end mill |
| Material | Premium micro-grain carbide |
| Cutting edge | 4 flutes, flat end (square end), center cutting |
| Hardness range | Hardened steels HRC45–55(for GP-4 design) |
| Coating | High-performance TiAlN / AlTiN coating for wear and heat resistance |
| Applications | Side milling, slotting and finishing in steels, alloy steels, cast iron |
| Machine type | CNC machining center, CNC milling machine. |
Ideal for side milling, slotting and finishing operations in steels, alloy steels, hardened steels and cast iron.
4 flute design increases feed rate capability and improves surface finish compared with 2 flute end mills.
Short flute geometry offers high rigidity, reducing deflection and vibration in deep cavity and mold machining.
High-performance coating provides excellent wear and heat resistance for long tool life in high-speed machining.
Recommended for CNC machining centers in mold and die, precision tooling and general engineering applications
