Built from high speed steel with a titanium carbonitride (TiCN) finish, this tool delivers improved surface hardness and wear resistance compared to uncoated HSS. The 1 inch cutting diameter and 3-flute spiral geometry provide a balance of chip clearance and cutting efficiency. The right-hand cut and right-hand flute configuration makes it compatible with standard vertical and horizontal milling machine spindles. Centercutting capability allows plunge milling in addition to peripheral cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on cast iron, non-ferrous metals, and steel in job shop, maintenance, and production environments. The 3\/4 inch straight-cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw style toolholders. The regular-length configuration fits most knee mills, CNC machining centers, and manual mills where extended reach is not required. Machinists and tool-and-die professionals will find this tool appropriate for slotting, profiling, and pocketing operations within its specified length-of-cut range.\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 for standard-depth milling passes\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with TiCN coating for extended tool life on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design balances chip evacuation and feed rate capability\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and reduced chatter\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for use with conventional milling machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for primary workpiece materials including cast iron (K), non-ferrous metals (N), and steel (P) as defined by ISO material group codes.

Secure the shank fully into a clean, properly sized end mill holder before tightening the set screw against the Weldon flat. Always power down and lock out the spindle before changing tooling. Follow shop-standard runout inspection procedures after mounting to verify concentricity before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 3\/4 inch (0.7500 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: TiCN\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\u003eExtended Reach\u003c\/strong\u003e: No\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-3\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: C39721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700335509810,"sku":"C39721","price":195.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a022362c5b0b50f794f1f1e91cd1db7b.jpg?v=1788389091","url":"https:\/\/voomisupply.com\/products\/cleveland-c39721-square-end-mill-1-in-3-flute-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
