MAYKESTAG Speedcut 4.0-Inox HPC Solid Carbide End Mill 5mm Long Series 4 Flute

Maykestag Speedcut 4.0-Inox HPC Solid Carbide End Mill 5mm Long Series

Professional 5mm Speedcut 4.0-Inox HPC solid carbide end mill from Maykestag, featuring a long-series design, four flutes, unequal 39°-42° spiral angles, Type N geometry and ULTRADUR coating for high-performance milling, particularly in stainless steels and demanding steel applications.

The Maykestag Code 8247 Speedcut 4.0-Inox is a high-performance solid carbide end mill engineered for controlled, efficient machining where cutting stability, surface finish and tool life are important. The unequal spiral geometry helps reduce the regular cutting-force pattern associated with conventional equal-helix cutters, supporting smoother machining and reduced vibration under demanding cutting conditions. This 5mm version features four flutes, providing increased cutting-edge engagement for productive milling operations.

Designed for High-Performance INOX Milling

The Code 8247 is engineered around unequal 39°-42° spiral angles which help reduce harmonic vibration and promote a more stable cutting action. On this 5mm cutter, four flutes provide increased cutting-edge engagement for productive milling while the unequal helix geometry helps maintain smooth cutting behaviour. The ULTRADUR coating adds further wear protection, while the solid-carbide construction provides the rigidity required for accurate machining. Used with the correct cutting speed, feed rate, tool holding and machining strategy, the Speedcut 4.0-Inox is designed to deliver dependable productivity and consistent results.
