With a 13\/64-inch (0.2031-inch) cutting diameter and a 9\/16-inch length of cut, it handles slotting, profiling, and peripheral milling operations on a range of workpiece materials. The 30-degree helix angle promotes efficient chip evacuation while maintaining edge stability. Center-cutting geometry allows plunge entry, adding versatility without a secondary tool change. Machinists, toolmakers, and CNC operators install this tool in standard end mill holders or Weldon-flat collet chucks.\u003c\/p\u003e\n\u003cp\u003eThe C33031 is suited for milling cast iron, non-ferrous metals, and steel in both manual and CNC milling applications. Its straight cylindrical shank with Weldon flat accepts standard 3\/8-inch end mill holders across most knee mills, bed mills, and machining centers. The double-end configuration provides two usable cutting ends, extending tool life between purchases. Right-hand cut and right-hand flute geometry are standard for conventional and climb milling on most horizontal and vertical spindle machines. The uncoated HSS construction makes it easy to resharpen in shops with tool grinding capability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design — two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — supports direct plunge milling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle for balanced chip flow and edge strength\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank with Weldon flat for secure tool holding\u003c\/li\u003e\n  \u003cli\u003eUncoated HSS construction — resharpenable and compatible with standard grinding equipment\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — fits standard spindle rotation on vertical and horizontal mills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch end mill holders and Weldon-flat collet systems.

Power down and lock out the spindle before changing tooling, in accordance with OSHA lockout\/tagout procedures. Verify runout with a dial indicator after seating the tool to confirm proper concentricity before cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 13\/64 inch (0.2031 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: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 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: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-4C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: C33031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709231923506,"sku":"C33031","price":67.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af57ac65c957ce33e5a691b186026d7c.jpg?v=1788453156","url":"https:\/\/voomisupply.com\/products\/cleveland-c33031-square-end-mill-13-64-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
