It features a 0.5-inch (12.70 mm) mill diameter, a 1.625-inch length of cut, and a 4-inch overall length with a matching 0.5-inch shank diameter. The 38-degree helix angle promotes aggressive chip evacuation and reduces cutting forces during side milling and slotting operations. An AlTiCrN coating delivers excellent thermal resistance and wear protection, making this tool well-suited for dry or semi-dry cutting of hardened steels and high-temperature alloys. This end mill is installed by machinists and tool-and-die professionals in CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for use in CNC vertical and horizontal machining centers where high material removal rates and surface finish quality are required. The five-flute, right-hand cutting, right-hand spiral geometry balances chip load per flute with core strength. The variable index design reduces harmonic vibration during long side-wall cuts, making it particularly effective for finishing passes in steel, stainless, and similar ferrous materials. Single-end configuration means the tool is replaced rather than flipped when worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrN coating provides elevated heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e5-flute design increases feed rates compared to standard 4-flute geometry while maintaining finish quality\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eVariable index spacing minimizes chatter and harmonic vibration during extended cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and edge retention in tough alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style solid carbide square end mill for CNC machining centers and manual mills accepting a 0.5-inch straight shank, part of the ACCUPRO HS series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by qualified machinists following standard toolholder torque and runout procedures for CNC milling applications.
