Built from M42 cobalt high-speed steel, it features a TiCN (titanium carbonitride) finish that extends tool life by reducing friction and resisting wear at elevated cutting temperatures. The double-end design provides two usable cutting ends, maximizing value per tool. With a 0.1563-inch (5\/32 inch) cutting diameter, a 0.4375-inch (7\/16 inch) length of cut, and a 30-degree helix angle, this end mill is engineered for spiral-flute cutting in stainless steel, high-temperature alloys, and steel. It is installed and run by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThe C32976 belongs to the Cleveland HDC-4C series, a line optimized for milling primary workpiece materials coded M (stainless steel), P (steel), and S (high-temperature alloys). Its centercutting geometry allows direct plunge entry into the workpiece without pre-drilling. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw style tool holders with a 3\/8-inch bore. The regular-length profile fits most vertical machining centers and manual knee mills where clearance is not a constraint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction provides heat and wear resistance beyond standard HSS in difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends cutting life in stainless steel and high-temperature alloy applications\u003c\/li\u003e\n\u003cli\u003eDouble-end design delivers two cutting ends per tool, extending overall tool value\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes smooth chip evacuation and reduces chatter\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration suits standard spindle rotation on most machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 3\/8-inch bore end mill holders, collet chucks, or Weldon-flat set-screw holders.

Ensure the machine spindle is fully stopped and locked out before loading or removing the tool from the holder. Verify that the holder bore matches the 3\/8-inch shank diameter and that the Weldon flat is properly aligned with the set screw to prevent axial pullout under load. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material and tool diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical with Weldon Flat\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\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\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HDC-4C\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: C32976\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699024396594,"sku":"C32976","price":69.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82c4fc12cd69fc20b83bbedaa5b44f75.jpg?v=1788371332","url":"https:\/\/voomisupply.com\/products\/cleveland-c32976-square-end-mill-5-32-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
