Built to the HG-4C series specification, it carries a titanium nitride (TiN) finish that increases surface hardness and extends tool life in demanding cuts. The cutter measures 7\/8 inch in diameter with a 5-inch length of cut, making it an extra-long reach tool suited for deep-pocket and deep-slot work. The 30-degree spiral flute geometry promotes efficient chip evacuation, and the centercutting design allows plunge entry. Machinists and CNC operators install this tool in vertical mills, machining centers, and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThe C33451 is rated for use on cast iron, non-ferrous metals, and steel. The extra-long 5-inch length of cut is well suited to deep cavity milling, side wall finishing, and full-depth slotting where standard-length end mills cannot reach. The straight cylindrical shank with Weldon flat accommodates standard side-lock toolholders, reducing pull-out risk under heavy lateral loads. Right-hand cut, right-hand flute orientation is standard for conventional and climb milling on typical CNC and manual setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch mill diameter with matching 7\/8 inch straight shank for direct toolholder fitment\u003c\/li\u003e\n  \u003cli\u003e5-inch length of cut rated for deep-pocket and deep-slot machining\u003c\/li\u003e\n  \u003cli\u003eTiN coating improves surface hardness and reduces tool wear on ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes chip flow out of deep cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on shank for secure side-lock toolholder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard vertical machining centers, CNC mills, and manual knee mills accepting 7\/8 inch straight-shank toolholders.

Power down and lock out the spindle before loading or unloading the tool. Seat the Weldon flat against the set screw in the side-lock toolholder to the tool manufacturer's recommended engagement depth to prevent axial pull-out. Verify runout with a dial indicator after seating before commencing a cut, particularly given the extra-long reach of this tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 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: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 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\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eLength Type\u003c\/strong\u003e: Extra Long\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: C33451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715925573938,"sku":"C33451","price":256.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a7caf07d101aba68a6fbda3240b1bb5.jpg?v=1788519822","url":"https:\/\/voomisupply.com\/products\/cleveland-c33451-square-end-mill-7-8-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
