Built on the Series 4V05 platform, this single-end mill features four flutes with a 38-degree helix angle and an AlTiN (WP15PE) coating that supports elevated cutting temperatures and extends tool life in abrasive materials. The 3\/8-inch cutting diameter pairs with a 7\/8-inch length of cut, making it well suited for slotting, profiling, and peripheral milling operations where controlled chip evacuation and edge retention are critical. It is center-cutting, right-hand cut, and right-hand flute with a straight-cylindrical shank.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use in steel, stainless steel, superalloys, titanium, hard materials, and high-temperature alloys  -  material groups P, M, K, S, and H. It is a standard-reach, regular-length tool with no chipbreaker and no variable helix or variable index geometry, making it straightforward to program and apply in conventional CNC milling operations. Typical applications include finish and semi-finish milling on vertical machining centers and CNC mills across aerospace, oil and gas, and general metalworking production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in hard and abrasive workpieces\u003c\/li\u003e\n\u003cli\u003eAlTiN coating (WP15PE grade) extends tool life and supports dry or near-dry cutting in high-temperature alloys\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth chip flow and reduces cutting forces in deep cuts\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle configurations\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 3\/8-inch shank fits standard collet chucks and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC vertical or horizontal machining centers.
