It carries an 11\/64-inch (0.1719 inch decimal) cutting diameter and a 1\/2-inch length of cut, mounted on a 3\/8-inch straight cylindrical shank with a Weldon flat for positive drive retention. The 30-degree helix angle promotes chip evacuation and smooth cutting action across a range of workpiece materials. At 2-3\/8 inches overall length, this is a regular-length tool suited for standard-reach applications where rigidity is a priority. It is installed and used by machinists, tool-and-die makers, and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThe C33143 is rated for use on cast iron, non-ferrous metals, and steel workpieces. Its center-cutting geometry allows direct plunge entry as well as conventional peripheral milling, making it useful for slotting, profiling, and pocket milling operations. Right-hand cut and right-hand spiral flute configuration aligns with standard spindle rotation on most vertical milling equipment. It carries no coating, which makes re-sharpening straightforward and keeps tool cost low for general shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11\/64-inch (0.1719 inch) cutting diameter with 1\/2-inch length of cut\u003c\/li\u003e\n  \u003cli\u003e4-flute, spiral flute configuration with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for use in standard spindle-direction setups\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch straight cylindrical shank with Weldon flat for secure tool holding\u003c\/li\u003e\n  \u003cli\u003eUncoated high speed steel construction for easy resharpening and general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling chucks, Weldon-flat end mill holders, and collet chucks accepting a 3\/8-inch shank diameter.

Secure the Weldon flat against the set screw in the tool holder before spindle engagement; never run a tool that is not fully seated and clamped. Inspect the cutting edges for chipping or wear before each use and replace or resharpen when wear land becomes visible. Follow shop safety protocols including eye protection and guarding whenever the spindle is in motion.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/64 inch (0.1719 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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/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: 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\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: HG-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: C33143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694244069682,"sku":"C33143","price":52.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cf024b29313a23328b849bfa612d78b.jpg?v=1788322133","url":"https:\/\/voomisupply.com\/products\/cleveland-c33143-square-end-mill-11-64-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
