Built on the HSV-4 series platform, it features a 0.5-inch mill diameter, a 1-inch length of cut, and a 0.0300-inch corner radius that reduces stress concentrations at the tool tip during both roughing and finishing passes. The variable pitch geometry helps suppress chatter at higher feed rates, making it suitable for demanding metal removal operations. At 3 inches overall length with a 0.5-inch straight cylindrical shank, it seats securely in standard high-precision toolholders. The APLUS PVD coating extends tool life in abrasive ferrous materials.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and milling machines where the workpiece material is low-alloy steel, medium-alloy steel, tool steel, or cast iron. The single-end, right-hand cutting configuration suits conventional finishing and semi-finishing operations on ferrous components. It is appropriate for shops running production or prototype work that requires consistent corner geometry and tight dimensional tolerances. High-precision toolholders are recommended to take full advantage of the 0.0005-inch maximum TIR specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300-inch corner radius with tolerance of -0.0020 to 0.0020 inches for repeatable edge geometry\u003c\/li\u003e\n\u003cli\u003eVariable pitch flute spacing reduces harmonic vibration during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eAPLUS PVD coating provides wear resistance in steel and cast iron without altering edge sharpness\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction maintains rigidity and dimensional stability under high cutting loads\u003c\/li\u003e\n\u003cli\u003eRight-hand flute, right-hand cut  -  compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eRated for both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-precision toolholders in CNC milling applications involving low-alloy steel, medium-alloy steel, tool steel, and cast iron workpiece materials.

Seat the shank fully into a high-precision collet or milling chuck and torque the retention mechanism according to the toolholder manufacturer specifications. Verify runout with a dial indicator before committing to a production cut  -  maximum TIR is 0.0005 inches.
