MAYKESTAG Speedcut 4.0 Universal HPC Solid Carbide End Mill 7mm Long Series 4 Flute TWINDUR

Maykestag Speedcut 4.0 Universal HPC Solid Carbide End Mill 7mm

Professional 7mm Speedcut 4.0 Universal HPC end mill manufactured from solid carbide (VHM), featuring four flutes, unequal 35°-38° spiral angles, long-series geometry, a 0.25mm x 45° corner chamfer and Maykestag TWINDUR coating for high-performance universal milling applications.

The Maykestag Code 8717 Speedcut 4.0 Universal is a high-performance solid-carbide end mill developed for accurate and productive milling across a broad range of engineering materials. The cutter combines four cutting edges with different spiral angles to provide a controlled cutting action while helping reduce the tendency towards vibration during demanding machining operations. Its long-series construction provides additional working reach, while the precision-ground geometry supports accurate profiling, shoulder milling, slotting and general end-milling applications.

Designed for Universal HPC Milling

The four-flute design provides multiple cutting edges for efficient material removal, while the unequal 35°-38° spiral geometry helps prevent all cutting edges from generating identical cutting-force impulses at the same frequency. This helps promote a smoother cutting action and can reduce the tendency towards chatter when appropriate machining conditions are used.

The long-series configuration gives the cutter additional reach for deeper shoulders, profiles and machining situations where tool access is important. As with any long-series milling cutter, correct toolholding, minimum practical overhang and appropriate cutting data are important for maintaining rigidity and achieving the best possible surface finish and tool life.
