Built from micrograin carbide, it delivers consistent edge integrity and extended tool life under demanding cutting conditions. The 15\/32 inch (0.4688 inch) cutting diameter, 30-degree helix angle, and spiral flute geometry work together to produce clean cuts, efficient chip evacuation, and reduced cutting forces. With 4 flutes and a center-cutting configuration, this end mill handles both plunge and peripheral milling. It is suited for use in manual mills and CNC machining centers. Installation and operation are performed by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill fits applications requiring a 1\/2 inch shank in standard ER collets, side-lock holders, or shrink-fit tooling. The 1 inch length of cut and 3 inch overall length make it appropriate for shallow-to-medium depth pocketing, slotting, and contouring in production and job-shop environments. It is uncoated and optimized for use with cutting fluid or dry machining depending on the workpiece material. The Series 404 designation places it within OSG's regular-length square end mill line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003e4-flute, center-cutting design supports both plunge entry and peripheral cutting\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced vibration\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eRegular length profile balances rigidity and reach for general-purpose milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for use with 1\/2 inch collet chucks, end mill holders, and shrink-fit toolholders in manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed and operated by qualified machinists. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Seat the shank fully in the holder to the minimum engagement depth recommended by the toolholder manufacturer.
