Built from high speed steel (HSS), it features a 1 inch cutting diameter, a 1-7\/8 inch length of cut, and a 7\/8 inch straight-cylindrical shank with a Weldon flat for secure tool holding. The 30-degree spiral flute geometry promotes efficient chip evacuation, while the uncoated HSS construction makes it well-suited for general-purpose shop use. This tool is centercutting, allowing direct plunge entry without a pre-drilled hole. Overall length is 4-1\/8 inches. Machinists and tool-and-die professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThe C33180 is rated for primary workpiece materials including cast iron, non-ferrous metals, and steel. It fits conventional vertical milling machines, manual knee mills, and CNC machining centers with appropriate collet or end mill holders accepting a 7\/8 inch shank. The regular-length profile makes it a standard choice for face milling, slotting, and peripheral profiling where extended reach is not required. It is part of the Cleveland HG-4C series, which targets general-purpose HSS end milling across a broad range of shop materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with 1-7\/8 inch length of cut\u003c\/li\u003e\n\u003cli\u003e4 flutes with 30-degree right-hand spiral for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction, uncoated, for general-purpose use\u003c\/li\u003e\n\u003cli\u003e7\/8 inch straight-cylindrical shank with Weldon flat for positive drive\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in milling machine spindles and CNC machining centers accepting a 7\/8 inch straight shank.

Ensure the spindle is fully powered down and at rest before changing tooling. Secure the shank in a compatible end mill holder or collet to the full recommended engagement depth, utilizing the Weldon flat to prevent pull-out under load. Verify runout with a dial indicator before cutting to protect both the tool and workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (1.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/8 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: C33180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699663536434,"sku":"C33180","price":187.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cfdbda20a5ecccf7eb0d8c537c99121.jpg?v=1788378886","url":"https:\/\/voomisupply.com\/products\/cleveland-c33180-square-end-mill-1-in-4-flute-hss-hg-4c","provider":"Voomi Supply","version":"1.0","type":"link"}
