The cutter measures 5\/16 inches in diameter with a 9\/16-inch length of cut and a 3\/8-inch straight cylindrical shank with a Weldon flat. Overall length is 3-1\/2 inches. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and clean cutting action. This is an uncoated, centercutting tool capable of plunge entry as well as peripheral milling. Machinists and tool-and-die professionals are the primary users of this type of cutter.\u003c\/p\u003e\n\u003cp\u003eThe C42061 is suited for milling operations on cast iron, non-ferrous metals, and steel. Its regular-length classification makes it appropriate for general-purpose slotting, profiling, and pocketing at moderate depths of cut. The double-end configuration provides two usable cutting ends, extending tool life before replacement is required. It fits standard milling machine spindles and CNC machining centers that accept 3\/8-inch straight shanks. This cutter belongs to the Cleveland HD-2 series, which is positioned for production and maintenance machining environments where consistent performance on common ferrous and non-ferrous materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design with two usable cutting ends for extended tool life\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction suited for cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on 3\/8-inch shank for positive drive and reduced pullout risk\u003c\/li\u003e\n  \u003cli\u003eUncoated finish; part of the Cleveland HD-2 regular-length series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling machines and CNC machining centers accepting a 3\/8-inch straight cylindrical shank.

Ensure the spindle is fully powered down and locked out before changing or seating the end mill. Use an appropriate end mill holder or collet that properly engages the Weldon flat to prevent axial slippage during cutting. Verify runout after tool installation before beginning any material removal operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 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: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\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: C42061\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51696804364594,"sku":"C42061","price":62.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3d78b24262902389684327e7afb3aa1c.jpg?v=1788346446","url":"https:\/\/voomisupply.com\/products\/cleveland-c42061-square-end-mill-5-16-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
