It features a 1\/4 inch cutting diameter, a 0.03 inch corner radius, and four flutes with a 30-degree medium helix for balanced chip evacuation and surface finish. The AlTiN physical vapor deposition (PVD) coating provides heat resistance and extended tool life in ferrous and high-temperature alloy applications. The single-end, right-hand cutting geometry is suited for both roughing and finishing operations in CNC machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and similar toolholding setups where a straight cylindrical shank is required. It performs in applications involving tight-tolerance profiling, slotting, and contouring in materials that generate high cutting temperatures. Primary workpiece materials include superalloys, titanium alloys, Inconel, stainless steel, alloy steel, and cast iron. The 3\/4 inch length of cut and 2.5 inch overall length make it appropriate for standard-depth passes in precision part production.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating rated for high-temperature alloy and ferrous metal cutting\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentration and improves edge durability\u003c\/li\u003e\n\u003cli\u003eFour-flute right-hand spiral geometry supports both roughing and finishing passes\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix balances chip flow and cutting forces\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 1\/4 inch shank diameter.
