Built from high speed steel (HSS) with a titanium carbonitride (TiCN) coating, it delivers extended tool life under demanding cutting conditions. The 13\/16 inch cutting diameter pairs with a 1-7\/8 inch length of cut, giving machinists solid material removal in a regular-length form factor. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This is a centercutting tool, meaning it can plunge directly into a workpiece. It is part of the Cleveland HG-4C series, intended for high-performance milling in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe C33279 is suited for milling cast iron, steel, and non-ferrous metals such as aluminum and copper alloys. Its right-hand cut and right-hand spiral flute configuration is the standard orientation for conventional vertical and horizontal milling machine setups. The straight cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw style tool holders with a 5\/8 inch bore. This tool is appropriate for general-purpose profiling, slotting, and peripheral milling operations across a range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating provides increased surface hardness and reduced friction compared to uncoated HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and chip clearance\u003c\/li\u003e\n\u003cli\u003e4 flutes balance material removal rate with chip evacuation capacity\u003c\/li\u003e\n\u003cli\u003eStraight shank with Weldon flat ensures positive seating in set-screw tool holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — standard orientation for most milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders with a 5\/8 inch bore.

Use a calibrated torque wrench on the Weldon flat set screw to avoid under- or over-tightening the holder. Verify runout with a dial indicator after seating the tool before beginning a cut. Follow the machine manufacturer and tooling manufacturer guidelines for appropriate speeds and feeds based on workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 13\/16 inch (0.8125 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 (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (1.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\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\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: C33279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51703862067506,"sku":"C33279","price":171.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d53cc3cf8b1614e4aef8ebc5506d9e1c.jpg?v=1788419059","url":"https:\/\/voomisupply.com\/products\/cleveland-c33279-square-end-mill-13-16-in-4-flute-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
