Maykestag Speedcut 4.0 Universal HPC Solid Carbide End Mill 8mm Long Series 4 Flute TWINDUR

Maykestag Speedcut 4.0 Universal HPC Solid Carbide End Mill 8mm

Professional 8mm 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.

What is an HPC end mill? HPC stands for High Performance Cutting. An HPC end mill uses optimised cutting geometry and a rigid tool construction to support high-performance machining while maintaining dimensional accuracy, controlled chip formation and dependable cutting-edge engagement. The Speedcut 4.0 Universal Code 8717 combines solid-carbide construction, four flutes, unequal spiral angles and TWINDUR coating in a cutter intended for professional CNC and precision milling applications.

Why Choose Maykestag?

Maykestag is an Austrian cutting-tool brand specialising in precision-manufactured tools for professional machining. With milling cutters, consistent geometry, accurate dimensional tolerances and carefully controlled cutting edges are critical because they directly influence tool life, machining accuracy, vibration behaviour and surface finish.

The Code 8717 Speedcut 4.0 Universal series combines a rigid solid-carbide body with four cutting edges, unequal spiral geometry and TWINDUR coating. The result is a professional HPC cutter designed for workshops, toolrooms and CNC production environments where repeatable machining performance and accurate results are required.

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.
