End mills machine metals, plastics, and composites by rotating multi‑flute cutters for profiling, slotting, and 3D milling. Made from carbide or HSS with advanced coatings, they enable precise machining in mouldmaking, aerospace, automotive, and general CNC applications.
End mills are multi‑edge cutting tools used in milling operations to remove material through rotation and controlled feed movement along multiple axes. They perform slotting, profiling, contouring, pocketing, and 3D surface machining on metals, plastics, and composites. The process relies on optimized chip load, spindle speed, and toolpath strategies to maintain accuracy and surface quality. End mills are commonly manufactured from solid Cemented Carbide, high‑speed steel (HSS), or cobalt-alloyed high-speed-steels (HSS-E-PM) and are often coated with TiN, TiAlN, AlCrN, or DLC to improve wear resistance, heat stability, and tool life. Tooling design varies—flat‑end, ball‑nose, corner‑radius, variable‑helix, and multi‑flute geometries are selected based on material hardness, chip evacuation needs, and machining depth. High‑precision manufacturing ensures balanced cutting edges and rigidity for demanding CNC machining. Applications include mould and die milling, aerospace and automotive components, medical devices, precision machinery, and general metalworking where complex geometries and tight tolerances are required.

Citește mai multThe cost-effectiveness of high speed steels is strongly dependent on their alloy components. Strong fluctuations in the raw materials market and resulting price variations have compelled voestalpine BÖHLER Edelstahl to rethink the basic alloy concepts of the high speed steels in our product portfolio. The result is the patented BÖHLER S730 material, which is an economical alternative to the generally applicable standard sort 1.3243 or M35 (BÖHLER S705). Despite its economic advantage, BÖHLER S730 is fully equivalent to the standard 1.3243 in terms of performance.
