Built from M42 cobalt high-speed steel and finished with a TiCN (titanium carbonitride) coating, this end mill delivers improved hardness and heat resistance compared to standard HSS tooling. It carries a 1\/2-inch cutting diameter with a 2-inch length of cut, a 4-inch overall length, and a straight-cylindrical shank with Weldon flat for positive tool holding. The 30-degree helix spiral flute geometry promotes efficient chip evacuation. It is a centercutting design, allowing plunge entry into a workpiece. Machinists and CNC operators running production cells install and operate this class of tooling.\u003c\/p\u003e\n\u003cp\u003eThe C32681 is suited for milling high-temperature alloys, stainless steel, and steel. Its long-series length of cut makes it appropriate for applications requiring extended reach into pockets, slots, or profiles where a standard-length end mill cannot fully engage the workpiece. Right-hand cut and right-hand flute orientation are standard for conventional milling setups. The HGC-4C series designation places this tool in a product family optimized for these harder workpiece materials where tool life and edge integrity under heat are critical performance factors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating adds surface hardness and reduces built-up edge on stainless and high-temperature alloys\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances chip clearance with surface finish capability\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled starter hole\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut (2 inches) suits deep pocket and slot milling applications\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive engagement in set-screw tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-inch straight-shank or Weldon flat tool holders on vertical mills, CNC machining centers, and knee mills.

The machine spindle must be fully stopped and the control placed in an e-stop or lockout condition before changing tooling. Ensure the Weldon flat is aligned with the set screw in the tool holder and torque the set screw to the tool holder manufacturer's specification. Verify runout with a dial indicator after installation before initiating a cutting cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 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 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (1\/2 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\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HGC-4C\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: C32681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700717781298,"sku":"C32681","price":81.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a3bd9033f765e21c3fd95355e5407e1.jpg?v=1788394289","url":"https:\/\/voomisupply.com\/products\/cleveland-c32681-square-end-mill-1-2-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
