It features a 1\/2 inch cutting diameter, a 1 inch length of cut, and a 0.09 inch corner radius that reduces stress concentration at the tool tip and extends tool life in demanding applications. The micrograin carbide substrate provides rigidity and wear resistance, while the AlTiN coating adds thermal protection for high-speed and dry-cutting environments. Four right-hand spiral flutes with a 40-degree helix angle promote efficient chip evacuation. This tool is installed and operated by machinists and CNC programmers in job shop, production, and toolroom settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits applications requiring a controlled corner radius on finishing and semi-finishing passes in steels, stainless steels, cast iron, and high-temperature alloys. The centercutting geometry allows plunge entry, supporting ramping and helical interpolation strategies. With a 3 inch overall length and a 1\/2 inch shank diameter, it fits standard ER and end mill holders on vertical and horizontal machining centers as well as manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-temperature resistance in dry and semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003e0.09 inch corner radius reduces stress risers and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports plunge, ramp, and helical entry\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand spiral helix promotes effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 4 flutes for balance between strength and chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 1\/2 inch shank corner radius end mills in standard ER collet chucks, end mill holders, and hydraulic toolholders on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures.
