Built from M42 cobalt high-speed steel and finished with a titanium nitride (TiN) coating, it delivers extended tool life and heat resistance compared to standard HSS tooling. The cutter measures 0.875 inches in diameter with a 3.5-inch length of cut and a 5.75-inch overall length. It features four spiral flutes, right-hand cut, right-hand flute geometry, and a 30-degree helix angle. The centercutting design allows plunge entry. This end mill is installed by machinists and tool-and-die professionals on vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThe C32667 belongs to the long-series HGC-4C family, making it suited for applications requiring extended reach into deep pockets, slots, and stepped features. It is optimized for cutting high-temperature alloys, stainless steel, and carbon and alloy steels, covering workpiece material codes M, P, and S. The straight-cylindrical shank with Weldon flat accommodates standard end mill holders and side-lock toolholders. This is a single-end tool; once the cutting end is worn, the tool is replaced rather than indexed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for superior hardness and heat resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eTiN finish extends tool life and reduces friction during high-speed cuts\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without a pre-drilled entry\u003c\/li\u003e\n\u003cli\u003eLong-series length of cut (3.5 inches) provides reach for deep-pocket and slotting operations\u003c\/li\u003e\n\u003cli\u003eWeldon flat on shank prevents tool pullout under heavy axial loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders and side-lock toolholders accepting a 0.875-inch straight shank with Weldon flat.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Seat the shank fully into the holder and torque the set screw against the Weldon flat per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning production cuts, as excessive runout accelerates flute wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\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: 3.5 inches (3-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.75 inches (5-3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\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\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\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\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: C32667\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698826051890,"sku":"C32667","price":175.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23772337f7110782b3fb4da54cd04b74.jpg?v=1788368505","url":"https:\/\/voomisupply.com\/products\/cleveland-c32667-square-end-mill-7-8-inch-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
