With a 3\/16 inch diameter, 5\/8 inch length of cut, and 2 inch overall length, this tool delivers consistent performance in tight-tolerance work. The TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. The micrograin carbide substrate supports rigidity and edge retention. This tool is installed and operated by machinists and CNC operators working in job shop, production, and maintenance machining environments.\u003c\/p\u003e\n\u003cp\u003eThe 403-187511 is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where a small-diameter, short-length-of-cut tool is required. The centercutting design allows plunge entry, adding versatility to the tool's range of operations. With a right-hand cut and right-hand flute configuration, it is compatible with standard CNC machining centers and manual mills running conventional spindle rotation. The Series 403 designation places this tool within OSG's regular-length square end mill line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge milling operations\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral design balances chip clearance and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 3\/16 inch collets and tool holders on CNC machining centers and manual vertical mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Secure the shank in a properly sized 3\/16 inch collet or end mill holder and torque to the tool holder manufacturer's specification. Verify runout with a dial indicator before cutting.
