It features a 0.25 inch mill diameter, a 0.375 inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The two-flute geometry and right-hand spiral flute configuration suit slotting, profiling, and peripheral milling tasks. Manufactured from K600-grade solid carbide, this end mill delivers rigidity and wear resistance appropriate for hardened and difficult-to-machine materials. It ships in a bright, uncoated finish and is centercutting, allowing plunge entry into workpiece material. Licensed machinists and CNC operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers, knee mills, and manual milling machines operating on ferrous and non-ferrous metals. The 0.25 inch shank diameter fits standard 1\/4 inch collets and toolholders. Its single-end design, two-flute layout, and 0.375 inch length of cut make it well-matched to slotting passes, contour milling, and pocket-roughing work where chip clearance and access to tight geometries are priorities. The Series AADF designation identifies it within the KENNAMETAL standard catalog line for general-purpose solid carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eK600-grade solid carbide construction for rigidity and extended tool life in demanding cuts\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle supports aggressive chip evacuation and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — ready for use on a broad range of work materials\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker, no variable helix, no variable index — consistent geometry for predictable results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/4 inch collets and toolholders.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm collet condition and runout before seating the shank to maintain diameter tolerances within the specified range.
