High-performance mill for demanding machining tasks
The Solid Carbide HPC-S Mill with Chip-Splitter is a precise machining tool specifically developed for roughing and finishing. Equipped with four flutes and useful chip-splitters, this model produces very short chips. This enables significantly improved chip evacuation and effectively prevents disruptions caused by chip jamming. The combination of solid carbide and the special TiAlN coating RT405 makes the milling cutter a well-thought-out solution for modern manufacturing environments where tool life and process reliability are paramount.

Applications
This tool is excellently suited for versatile machining tasks such as shoulder milling, slot milling, drilling, ramping, and trochoidal milling. Thanks to the centre cutting geometry, plunging operations can be executed directly and safely. The mill is designed for use in structural steel, tempered steel, tooling steel, stainless steel, and cast iron.

Special features
A key feature is the integrated chip-splitters on the cutting profile, which prevent the formation of long continuous chips even at high cutting depths. The unequal helix angle of 38°/40° noticeably reduces vibrations and supports efficient workflows through high running smoothness. The PVD-TiAlN high-performance grade (RT405) reliably protects the carbide substrate from thermal and mechanical stress.
