Built from M42 cobalt high-speed steel, this tool delivers heat resistance and edge retention in demanding cutting applications. It features a 15\/16-inch (0.9375 inch) cutting diameter, a 1-7\/8-inch (1.875 inch) length of cut, and a 30-degree helix angle that promotes efficient chip evacuation. The bright, uncoated finish makes it straightforward to inspect for wear. This end mill is installed and operated by machinists and tool-and-die professionals working with manual mills, CNC machining centers, and knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose peripheral and slot milling in shop environments where cobalt tooling is selected over carbide for its toughness in interrupted cuts or inconsistent workpiece hardness. The 4-flute configuration provides a good balance of chip clearance and surface finish in steels, alloy steels, stainless, and similar materials. The right-hand cut and right-hand spiral flute direction are standard for conventional milling setups. The center-cutting geometry allows plunge entry as well as lateral passes without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance compared to standard M2 tooling\u003c\/li\u003e\n  \u003cli\u003e4 spiral flutes with right-hand cut and right-hand helix for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting action and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — easy visual inspection of cutting edges between passes\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 3\/4-inch shank diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end square end mill with a 3\/4-inch shank, compatible with collet chucks, end mill holders, and milling machine spindles sized for 3\/4-inch straight shanks in manual or CNC milling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists.
