Manufactured from M7 high speed steel in an uncoated finish, it features a 0.125-inch cutting diameter and a 30-degree helix angle with spiral flutes that promote efficient chip evacuation. With two flutes and a centercutting design, this tool handles both slotting and plunge-cutting operations. The 0.375-inch shank diameter provides solid rigidity in standard end mill holders and collet chucks. Machinists and tool-and-die professionals working on manual mills or CNC machining centers are the typical installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for light-duty to medium-duty material removal on ferrous and non-ferrous workpieces in production and job-shop environments. The double-end configuration doubles usable tool life before replacement. Right-hand cut and right-hand flute geometry match standard spindle rotation on conventional milling machines. The 0.1875-inch length of cut is appropriate for shallow-depth slot milling, profiling, and edge work on small-scale components where precision and control are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design extends usable tool life by providing two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction offers good toughness and wear resistance for general metalworking\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with spiral flutes promotes smooth cutting action and chip clearance\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suits applications where coating is unnecessary or where re-sharpening is anticipated\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for use with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for 3\/8-inch end mill holders, collet chucks, and milling machines accepting a 0.375-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and CNC operators in milling machine spindles using an appropriately sized collet or end mill holder.
