It measures 25\/64 inch (0.3906 inch decimal) in cutting diameter with a 1 inch length of cut and a 4-1\/2 inch overall length. The 1\/2 inch straight-cylindrical shank includes a Weldon flat for positive tool retention in standard end mill holders. A 30-degree helix angle promotes efficient chip evacuation, and the spiral flute geometry is designed for right-hand cut and right-hand flute direction. This tool is intended for use by machinists and tool-and-die professionals on manual mills, CNC machining centers, and knee mills.\u003c\/p\u003e\n\u003cp\u003eThe C33040 belongs to the Cleveland HD-4C series and is suited for milling operations on cast iron, non-ferrous metals, and steel. Its centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole, making it practical for slot milling, profile milling, and step milling. The regular-length geometry fits standard toolholders and works in both job-shop and production environments where HSS tooling is preferred for its toughness and regrindability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end configuration extends tool life by providing two usable cutting ends\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a starter hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle for improved chip flow and reduced cutting pressure\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on 1\/2 inch shank prevents tool pullout under load\u003c\/li\u003e\n  \u003cli\u003eUncoated high speed steel construction allows easy regrinding\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2 inch end mill holders and collet chucks on manual knee mills and CNC machining centers.

Secure the shank fully into the holder with the Weldon flat engaged against the setscrew to prevent axial pullout. Ensure the spindle is completely stopped and machine is in a safe, locked-out state before changing tooling. Do not exceed the tool's rated length of cut when programming depth of engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inch)\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: 1 inch (0.3906 inch decimal noted; LOC 1.0000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eDouble End\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\u003ePrimary Workpiece Materials\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\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: C33040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693735280946,"sku":"C33040","price":74.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ede9cc324551e273d2910e73bc5ed9f.jpg?v=1788316732","url":"https:\/\/voomisupply.com\/products\/cleveland-c33040-square-end-mill-25-64-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
