Built from micrograin carbide and coated with TiN (Titanium Nitride), it delivers extended tool life and reduced friction at the cutting edge. The 4-flute, single-end configuration provides excellent surface finish and chip evacuation across a wide range of workpiece materials. With a 3\/8 inch mill diameter, a 1 inch length of cut, and a 2.5 inch overall length, this end mill fits standard tool holders and suits general-purpose CNC milling and manual mill operations in job shops and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, aluminum and other non-ferrous metals, and hardened materials. The 30-degree right-hand helix and right-hand cutting direction make it a reliable choice for conventional and climb milling passes. Center-cutting capability allows for direct plunge entry where the operation requires it, adding versatility for pocketing and slotting work in both residential toolroom and industrial production contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute design improves surface finish and increases feed rates versus 2-flute alternatives\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral helix promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry permits direct plunge entry for pocketing and slotting\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 3\/8 inch shank fits standard collets 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 collets and end mill holders on CNC machining centers and manual vertical mills.
