It features a 0.2188-inch mill diameter, a 0.03-inch corner radius, and four right-hand helical flutes with a 30-degree helix angle. The cutting edge is WXL-coated via PVD process, providing enhanced wear resistance and thermal stability. This is a single-end, centercutting tool, making it capable of plunge entry as well as peripheral and slot milling. It is suited for both roughing and finishing passes and is manufactured from micrograin carbide for consistent performance in demanding applications.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills across job shops, aerospace, and general metalworking environments. It is engineered for use with a standard straight-shank toolholder. Its primary workpiece material categories include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, making it a versatile choice for machinists working across multiple material types in production and maintenance operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03-inch corner radius reduces stress concentrations and extends tool life at the cutting edge\u003c\/li\u003e\n\u003cli\u003eWXL PVD coating improves hardness and oxidation resistance for high-performance cutting\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction with medium helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCompatible with material grades P, M, K, N, S, and H per standard workpiece classification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-shank cylindrical toolholders.
