Built from M42 cobalt high-speed steel, it offers superior heat and wear resistance compared to standard HSS tooling. The cutter features a TiN (titanium nitride) coating that further extends tool life and reduces friction at the cutting edge. With a 7\/16-inch cutting diameter and a 1-3\/4-inch length of cut, this tool handles slotting, profiling, and peripheral milling operations. Spiral flutes with a 30-degree helix angle promote efficient chip evacuation. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling high-temperature alloys, stainless steel, and general steel workpieces. The HGC-4C long series designation provides additional reach compared to standard-length tooling, making it useful where extended projection is needed without sacrificing rigidity. The straight-cylindrical shank with a Weldon flat accommodates standard side-lock tool holders with a 3\/8-inch bore. It is centercutting, allowing direct plunge entry into the workpiece. Right-hand cut and right-hand flute geometry follow conventional milling orientation for use in standard spindle configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e4-flute, spiral design with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eLong series (HGC-4C) provides greater reach than standard-length end mills\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on straight shank ensures positive drive in side-lock holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 3\/8-inch bore side-lock or Weldon-flat tool holders.

Verify spindle and tool holder bore size matches the 3\/8-inch shank diameter before mounting. Secure the Weldon flat against the set screw in the holder to prevent pull-out under cutting load. Confirm correct spindle rotation direction (right-hand) before engaging the workpiece, and apply appropriate cutting fluid or air blast for chip clearance in stainless and alloy applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inches (1.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HGC-4C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, 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: C32661\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720839463218,"sku":"C32661","price":76.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff6bb6719c66235d07ac13e4cb26a055.jpg?v=1788569771","url":"https:\/\/voomisupply.com\/products\/cleveland-c32661-square-end-mill-7-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
