Built from solid carbide and coated with titanium nitride (TiN), it delivers hardness and wear resistance suited to ferrous and non-ferrous materials. The mill measures 0.2656 inches in diameter with a 0.75-inch length of cut and an overall length of 2.5 inches. Four right-hand flutes with a right-hand cutting direction provide efficient chip evacuation and a smooth surface finish. Machinists and tool-and-die professionals working in job shops, production environments, and maintenance facilities rely on this geometry for precise profiling work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where ball-nose geometry is required for radius profiling, cavity work, and complex contoured surfaces. The 5\/16-inch shank diameter fits standard collets and end mill holders common in both horizontal and vertical milling setups. The TiN coating extends tool life in dry or light-coolant cutting conditions on steels, cast iron, aluminum, and similar workpiece materials. It is a single-end tool, so the cutting end is not reversible.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and improves wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral geometry for efficient chip removal and smooth finish\u003c\/li\u003e\n  \u003cli\u003eBall-nose profile produces accurate radii and contoured 3D surfaces\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with a 5\/16-inch straight shank for broad collet compatibility\u003c\/li\u003e\n  \u003cli\u003e0.75-inch length of cut supports moderate depth profiling without excessive overhang\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/16-inch collets and end mill holders on CNC machining centers and manual vertical mills where ball-nose solid carbide end mills are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Secure the shank fully within the collet or end mill holder to the recommended engagement depth and torque the holder per the machine tool manufacturer specifications before cutting. Inspect the cutting edges for chips or wear before each use, and confirm spindle runout is within acceptable limits to avoid premature edge failure. Follow your machine tool and facility safety protocols when changing tooling, including ensuring the spindle is fully stopped and locked out.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2656 inches (17\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E699924525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755863736626,"sku":"E699924525","price":65.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f05a87849784199494a64a06d647cfd0.jpg?v=1788960684","url":"https:\/\/voomisupply.com\/products\/hertel-e699924525-ball-end-mill-0-2656in-4-flute-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
