Built from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers increased hardness and heat resistance compared to standard HSS tooling. The cutter measures 0.75 inches in diameter with a 3-inch length of cut and a 5.25-inch overall length. Its 4-flute, spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and stable cutting performance. Licensed machinists and tool-and-die shops rely on this series for consistent results in long-reach applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on high-temperature alloys, stainless steel, and steel. Its long-series geometry makes it appropriate for applications requiring extended reach beyond standard flute lengths. The center-cutting design allows plunge entry, giving operators flexibility for interpolated pocketing, slotting, and peripheral milling in a single setup. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and Weldon-style chucks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated red hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN finish reduces friction and extends tool life in ferrous and high-temp alloy cuts\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports plunge milling without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eLong-series HGC-4C profile provides extended reach over standard-length tooling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with conventional CNC and manual mill spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/4-inch end mill holders, Weldon-flat set-screw chucks, and shrink-fit holders bored to 0.75 inches.

Ensure the spindle is fully de-energized and locked out before inserting or removing tooling. Verify holder bore concentricity and torque set screws to the holder manufacturer's specification. Confirm correct spindle rotation direction (right-hand) before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical with Weldon Flat\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HGC-4C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C32683\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699162546482,"sku":"C32683","price":179.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/25077ab8bbc678226037d35cb889bb52.jpg?v=1788372977","url":"https:\/\/voomisupply.com\/products\/cleveland-c32683-square-end-mill-3-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
