Built from M42 cobalt high-speed steel, this single-end mill features a 17\/64-inch (0.2656-inch) cutting diameter, a 3\/4-inch length of cut, and a 2-1\/2-inch overall length. The four-flute, right-hand spiral configuration provides efficient chip evacuation and a stable cutting action. The straight cylindrical shank with Weldon flat accepts standard end mill holders and collet chucks. Machinists and tool-and-die professionals select cobalt end mills where heat and wear resistance are critical and carbide tooling would be cost-prohibitive.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling stainless steel, high-temperature alloys, and general steel workpieces at moderate speeds and feeds. Its centercutting geometry allows plunge entry into the workpiece, supporting slotting, profiling, and pocket milling operations. The HGC-4C series regular-length geometry keeps tool deflection low in typical setups on CNC machining centers and manual knee mills. Primary workpiece materials include high-temperature alloys, stainless steel, and steel, where cobalt grades outperform standard HSS tooling in heat-intensive cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral flute design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports direct plunge entry and slotting operations\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and surface finish\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with Weldon flat for positive grip in end mill holders\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for regrinding and resharpening to extend tool life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch end mill holders, collet chucks, and Weldon-flat set-screw holders on CNC machining centers and manual mills.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Secure the Weldon flat against the set screw in the holder to prevent pullout under axial cutting loads. Verify runout at the cutting end before beginning the cut; excessive runout accelerates edge wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 17\/64 inch (0.2656 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\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 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: 2-1\/2 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\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\u003eSeries\u003c\/strong\u003e: HGC-4C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\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: C32561\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690576085298,"sku":"C32561","price":77.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dcab498443d5293ac0bbca09d5a480c5.jpg?v=1788271958","url":"https:\/\/voomisupply.com\/products\/cleveland-c32561-square-end-mill-17-64-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
