Built from high speed steel (HSS), it carries a 0.5-inch cutting diameter with a 1.25-inch length of cut and an overall length of 3.25 inches. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action on a range of workpiece materials. This uncoated, spiral-flute tool is center-cutting, allowing it to plunge directly into a workpiece. It is installed and operated by machinists and tool-and-die technicians using standard vertical or horizontal milling machines and machining centers.\u003c\/p\u003e\n\u003cp\u003eThe C39651 is suited for milling cast iron, non-ferrous metals, and steel in both production and job-shop settings. Its straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw tool holders. The regular-length geometry makes it appropriate for shoulder milling, slotting, profiling, and peripheral milling applications where extended reach is not required. Right-hand cut and right-hand flute configuration match the standard spindle rotation of conventional milling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5-inch cutting diameter with 1.25-inch length of cut for standard-depth slotting and profiling\u003c\/li\u003e\n  \u003cli\u003e3-flute configuration balances material removal rate with chip clearance on steel and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness and regrindability in interrupted-cut conditions\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eStraight shank with Weldon flat seats securely in set-screw end mill holders\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains original geometry for straightforward resharpening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition for standard 0.5-inch bore end mill holders used in vertical mills, knee mills, and machining centers.

Ensure the machine spindle is fully de-energized and locked out before mounting or removing the end mill from its holder. Seat the shank fully into the holder to the recommended gauge-line depth and tighten the Weldon flat set screw to prevent axial pullout during cuts. Verify runout with a test indicator before initiating a cutting pass, particularly on finish operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical with Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C39651\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690500620594,"sku":"C39651","price":96.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04f1ec6422896e7363028408d65583de.jpg?v=1788270659","url":"https:\/\/voomisupply.com\/products\/cleveland-c39651-square-end-mill-0-5-in-3-flute-hss-hg-3","provider":"Voomi Supply","version":"1.0","type":"link"}
