MAYKESTAG Speedcut 4.0 Ultra Hard Steel 50-65 HRC DUALDUR HPC End Mill 4mm Long Series 4 Flute

Maykestag Speedcut 4.0 Ultra Hard Steel 50-65 HRC DUALDUR HPC End Mill 4mm

Professional 4mm Speedcut 4.0 Ultra Hard Steel HPC end mill manufactured from solid carbide (VHM), featuring Maykestag&s DUALDUR multi-layer coating, four-flute geometry, 50° VARIO spiral angle, Type H design and DIN 6527 L long-series construction for high-performance machining of hardened and high-tensile steels.

The Maykestag Code 8787 Speedcut 4.0 is a high-performance solid-carbide end mill developed especially for machining hardened and high-tensile steels. This Ultra Hard Steel version is specified for the demanding 50-65 HRC machining range and combines high tool rigidity with different spiral angles to support stable cutting and a high-quality machined surface, even under demanding cutting conditions. Maykestag specifies the cutter for roughing, rough-finishing and finishing operations, allowing multiple machining stages to be carried out with the same tool.

Product highlights

Designed for High-Performance Hard Milling

Hard machining places particularly high thermal and mechanical loads on a milling cutter. The Code 8787 addresses these demands through a rigid solid-carbide body, specialised cutting geometry and DUALDUR coating. The coating uses a multi-layer construction optimised for hard-material machining and high-temperature resistance, while the different spiral angles help promote stable cutting behaviour and a high-quality workpiece surface. Used with the correct cutting speed, feed rate, engagement and machine setup, the Speedcut 4.0 Ultra Hard Steel cutter is designed to provide productive and repeatable machining of hardened steels in its specified application range.
