Built on the H40ALV-RN-3 series platform, it features a 0.5-inch mill diameter with a 0.0300-inch corner radius and a 5\/8-inch length of cut. The Zplus PVD coating provides wear resistance and thermal stability across a broad range of workpiece materials. With a variable-pitch, high-helix geometry and a 6-inch overall length, this tool is suited for extended-reach applications where standard-length tooling cannot access the cut zone. Installation and setup require high-precision toolholders to achieve the rated 0.0003-inch maximum TIR.\u003c\/p\u003e\n\u003cp\u003eThis end mill is optimized primarily for aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The extra-long reach of 4.25 inches and reduced neck diameter of 0.475 inches make it well suited for deep-pocket milling, cavity work, and multi-axis machining setups where clearance is a constraint. It is a single-end, centercutting tool, allowing plunge entry and full contouring use in CNC machining centers running both roughing and finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with Zplus PVD coating for extended tool life across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius with tight tolerance of -0.0020 to 0.0020 inches for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eVariable-pitch, high-helix flute design reduces chatter and supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eExtra-long 4.25-inch reach with 0.475-inch neck diameter for deep-pocket and restricted-access milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and cutting action; h6 tolerance on both mill and shank diameters for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.

Confirm shank seating and runout before engaging the cut. Always verify spindle speed and feed rate parameters against the material being machined prior to running the tool.
