Built from high speed steel (HSS) with a titanium carbonitride (TiCN) finish, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The 7\/16-inch cutting diameter pairs with a 3\/8-inch straight-cylindrical shank that also accommodates a Weldon flat for secure set-screw retention. With a 1-inch length of cut and 2-11\/16-inch overall length, this is a regular-length tool suited for general-purpose slotting, peripheral milling, and plunge cutting in a shop or production environment. Licensed machinists and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThe C33260 is rated for primary workpiece materials including steel, cast iron, and non-ferrous metals. The four-flute, right-hand cut and right-hand spiral flute geometry with a 30-degree helix angle balances chip evacuation against surface finish. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, making it versatile for pocket milling and ramping operations. It carries the HG-4C series designation and is packaged individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and extends tool life versus uncoated HSS\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances chip flow and finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration suits standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on shank prevents set-screw slippage under heavy cuts\u003c\/li\u003e\n  \u003cli\u003eFour-flute design increases feed rate capability compared to two- or three-flute versions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in steel, cast iron, and non-ferrous metal workpieces.

Confirm spindle speed and feed rate are appropriate for the workpiece material and cutting diameter before engaging the cut. Always power down and lock out the machine before changing tooling. Inspect the cutting edges for chipping or wear before each use and replace the tool if edge condition is compromised.\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 (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 inch (1.0000 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\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: C33260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694439432498,"sku":"C33260","price":77.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06b03b670b918caf35ceaae6f747586a.jpg?v=1788324479","url":"https:\/\/voomisupply.com\/products\/cleveland-c33260-square-end-mill-7-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
