Manufactured from high speed steel (HSS), this tool features a 7\/16-inch cutting diameter, a 1-inch length of cut (LOC), and a 3\/8-inch straight cylindrical shank with Weldon flat. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Center-cutting geometry allows plunge entry directly into the workpiece. Overall length is 2-11\/16 inches. This is a right-hand cut, right-hand flute configuration in the HG-4C series, delivered uncoated and ready for immediate use.\u003c\/p\u003e\n\u003cp\u003eThe C41254 is suited for milling cast iron, non-ferrous metals, and steel in standard shop and production environments. The regular-length geometry fits most vertical knee mills, CNC machining centers, and manual mills using standard 3\/8-inch collets or end mill holders with Weldon flat set screws. Its spiral flute design and 4-flute count make it effective for slotting, peripheral milling, and profiling cuts where surface finish and tool rigidity both matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16-inch cutting diameter with 1-inch length of cut for standard depth milling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suitable for cast iron, steel, and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting and efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute configuration\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch straight-cylindrical shank with Weldon flat for secure toolholder engagement\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; part of the HG-4C series for general-purpose milling\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, collet chucks, and Weldon-style toolholders on vertical milling machines and CNC machining centers.

Ensure the machine spindle is fully stopped and the power is locked out before changing tooling. Secure the shank in a properly sized Weldon-flat holder or collet and torque the set screw or clamping mechanism per the toolholder manufacturer's specifications. Verify runout with a dial indicator before commencing cuts, and confirm spindle speed and feed rate match recommendations for the workpiece material and tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.0000 to 1.2500 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: 2-11\/16 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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\u003eVariable Index\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-4C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C41254\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720886485298,"sku":"C41254","price":71.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04be6932f222bfd9ab0d9ccec5a61ade.jpg?v=1788570514","url":"https:\/\/voomisupply.com\/products\/cleveland-c41254-square-end-mill-7-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
