Manufactured from sub-micrograin carbide in the IC908 grade with a PVD-applied TiAlN coating, this tip delivers consistent performance in demanding cutting applications. It features four flutes, a 0.375-inch cutting width, a 90-degree lead angle, and a 30-degree helix angle. The functional length is 0.510 inches with a maximum depth of cut of 0.280 inches. Right-hand cut orientation. This tip is installed and replaced by machinists and toolroom technicians as part of a modular end mill assembly.\u003c\/p\u003e\u003cp\u003eThe 5621318 is suited for milling operations across a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its ball nose geometry makes it appropriate for profiling, contouring, and 3D surface milling on both roughing and finishing passes. The replaceable tip design reduces tooling cost by allowing the cutting head to be swapped without replacing the full tool body.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC908 sub-micrograin carbide grade with PVD TiAlN coating for wear resistance across multiple material groups\u003c\/li\u003e\n\u003cli\u003eBall nose geometry with 0.375-inch cutting width and 0.190-inch corner radius for profiling and contouring\u003c\/li\u003e\n\u003cli\u003eFour flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.280 inches with 0.510-inch functional length\u003c\/li\u003e\n\u003cli\u003eReplaceable Multimaster MM EB style tip — no coolant-through, right-hand cut\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards; insert size .375A27\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replaceable tip for Multimaster MM EB series modular milling tool holders accepting the .375A27 insert size.
