AlTiN coating forms a stable aluminum oxide layer at elevated temperatures, providing superior thermal protection and oxidation resistance. Ideal for high-speed machining of hardened steels, stainless steels, and other difficult-to-cut materials. Manufactured from premium-grade solid carbide for maximum rigidity and edge retention. Maintains dimensional accuracy and cutting performance even under heavy cutting conditions on high-hardness workpieces. Solid carbide substrate rated at HRC 55, engineered to machine hardened materials up to HRC 45. Capable of performing both roughing and semi-finishing operations directly on heat-treated molds, reducing tool transitions and mold-making cycle time. 4-Flute Square End Design. 4-flute geometry provides higher feed rates and superior surface finish compared to 2-flute alternatives. Square end profile delivers clean, precise bottom edges for pocketing, profiling, and slotting applications. Extended Tool Life & Cost Efficiency. AlTiN coating combined with solid carbide substrate significantly extends tool life and reduces tool change frequency. Fewer interruptions mean improved machining rhythm and lower per-part production costs. Compatible with CNC machining centers, standard milling machines, engraving machines, and high-speed routers. Suitable for both production environments and job shop applications. D a size not listed? Your satisfaction is our top priority.
