It features a 0.375-inch diameter cutting head with a 0.75-inch length of cut and a 2.5-inch overall length. Constructed from M7 high speed steel, this tool runs uncoated with a 30-degree right-hand spiral helix and right-hand cutting direction. With two flutes and a regular-length profile, it suits standard milling operations where HSS tooling is preferred over carbide for toughness and regrindability.\u003c\/p\u003e\n\u003cp\u003eThis ball end mill is appropriate for use on manual mills, CNC machining centers, and knee mills in job shop, maintenance, and production environments. It is suited for profiling, contouring, and pocket milling in softer steels, aluminum, brass, and similar machinable metals. The 3\/8-inch shank diameter fits standard ER collets, side-lock holders, and weldon-style tool holders commonly found in both manual and CNC setups. It is a single-end tool, meaning the cutting geometry is on one end only.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.375-inch ball end diameter for contour and profile milling\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness and regrindability\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry for efficient chip evacuation in softer materials\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — ready for regrinding or use with cutting fluid\u003c\/li\u003e\n  \u003cli\u003eRegular-length profile with 0.75-inch LOC and 2.5-inch OAL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end ball end mill with a 3\/8-inch shank diameter, compatible with ER collet chucks, Weldon-style end mill holders, and similar 3\/8-inch bore toolholding systems used on manual and CNC milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom personnel. Power down and lock out the spindle before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque set screws or collet nuts per the toolholder manufacturer specifications. Inspect the cutting edges for chips or wear before each use and confirm runout with a dial indicator when precision profiling is required.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 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: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: 0.07 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: E211002402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747529326898,"sku":"E211002402","price":37.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51fe3ad2ba281426dc7ebd0387b5997f.jpg?v=1788881962","url":"https:\/\/voomisupply.com\/products\/hertel-e211002402-ball-end-mill-0-375-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
