Built from high speed steel, it offers a cutting diameter of 0.8125 inches (13\/16 inches) and a length of cut of 1.875 inches. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. It carries a straight cylindrical shank with a Weldon flat at 0.625 inches diameter and an overall length of 4 inches. This is an uncoated, center-cutting tool suitable for plunge and peripheral milling operations. Licensed machinists and toolroom operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe C39656 is rated for use on cast iron, non-ferrous metals, and steel — covering a broad range of production and maintenance machining applications. Its regular-length geometry suits standard knee mills, CNC machining centers, and manual Bridgeport-style machines where a compact, rigid tool is needed. The center-cutting design allows direct plunge entry without a pilot hole, which is practical in fixturing and cavity work. The HG-3 series designation indicates a general-purpose high speed steel line intended for shops that prefer uncoated tools for regrindability and cost control.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.8125-inch (13\/16-inch) cutting diameter with 1.875-inch length of cut\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral geometry for efficient chip flow in ferrous and non-ferrous cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design enables direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight shank with Weldon flat for positive tool holding\u003c\/li\u003e\n  \u003cli\u003eUncoated high speed steel — resharpenable for extended tool life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders and Weldon-flat collet chucks accepting a 0.625-inch shank diameter.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the Weldon flat against the set screw in the holder to prevent axial pullout under load. Confirm runout with a dial indicator before commencing a cut, and apply appropriate cutting fluid or air blast for the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.8125 inches (13\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.875 inches (1-7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical with Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\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: C39656\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700042563890,"sku":"C39656","price":154.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa91728ef23b8fff4f07a3dd508046bc.jpg?v=1788385318","url":"https:\/\/voomisupply.com\/products\/cleveland-c39656-square-end-mill-13-16-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
