Built to M42 cobalt steel grade, it runs a 9\/32-inch (0.2813 inch) cutting diameter with a 9\/16-inch length of cut and a 3\/8-inch straight-cylindrical or Weldon Flat shank. The 30-degree spiral flute geometry and TiCN finish work together to manage heat and extend tool life in demanding cuts. This is a double-end, centercutting tool, meaning it can plunge directly into a workpiece without a pre-drilled entry point. Machinists and toolroom technicians rely on it for slotting, profiling, and peripheral milling where tool life in tough materials is the priority.\u003c\/p\u003e\u003cp\u003eThe C32890 belongs to Cleveland's HDC-2 series, which targets high-performance cutting in stainless steel, alloy steel, and high-temperature alloys. It is a regular-length end mill suited for general-purpose setups on knee mills, CNC machining centers, and manual vertical mills. The right-hand cut and right-hand flute configuration make it compatible with standard spindle rotation. At 3-3\/8 inches overall length with a 3\/8-inch shank, it fits standard ER, collet chuck, or Weldon-style side-lock holders commonly found in production and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat resistance in stainless steel and high-temperature alloy cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends cutting edge life compared to uncoated tooling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eDouble-end configuration provides a second usable cutting end, extending tool value\u003c\/li\u003e\n\u003cli\u003eWeldon Flat or straight-cylindrical shank fits both side-lock and collet-style holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-fit cutting tool for standard 3\/8-inch shank toolholders used in vertical machining centers, knee mills, and manual milling machines. Primary workpiece materials listed are high-temperature alloy, stainless steel, and steel (material codes S, M, and P).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully into the toolholder to the recommended engagement depth before tightening — insufficient engagement increases runout and risk of tool pullout. Confirm spindle rotation direction matches the right-hand cut specification before starting the spindle. Inspect the cutting edges for chipping or wear before each use, particularly after cutting abrasive or work-hardening alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2813 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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 \/ Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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-2\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\u003eLength Type\u003c\/strong\u003e: Regular\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: C32890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690064085298,"sku":"C32890","price":66.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfb90bb252cfeea42d88c64481f83dd6.jpg?v=1788266295","url":"https:\/\/voomisupply.com\/products\/cleveland-c32890-square-end-mill-9-32-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
