With a 5\/8 inch head diameter and an 82-degree included angle, it produces accurately angled recesses that match flat-head screw profiles common in carbon steel and cast iron applications. The straight cylindrical shank measures 3\/8 inch in diameter, providing positive chuck engagement on standard drill presses, CNC machines, and hand drills. An oxide coating improves surface lubricity and wear resistance during cutting. This tool is installed and used by machinists, tool-and-die workers, and maintenance mechanics working in metal fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThe C46120 is suited for countersinking operations in carbon steel and cast iron stock. Its single-flute geometry reduces chatter and produces a clean, consistent finish in these materials. Typical applications include preparing bolt and screw holes in structural components, machinery frames, and plate assemblies where a flush fastener seating is required. The right-hand cutting direction is compatible with standard drill press and lathe rotation. This tool is well-matched to production shops and maintenance facilities that require repeatable countersink geometry on a variety of workpiece thicknesses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch head diameter for standard flat-head fastener recesses\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches common flat-head screw profiles\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design reduces chatter and improves finish consistency\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and heat resistance during cutting\u003c\/li\u003e\n  \u003cli\u003eOxide coating enhances wear resistance and reduces friction\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch straight cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in carbon steel and cast iron material applications.

Secure the workpiece firmly before beginning the countersinking operation and ensure the drill press or machine spindle is stopped before changing or adjusting the tool. Use appropriate cutting fluid when working with ferrous metals to extend tool life. Do not exceed the recommended speed range for high speed steel tooling in the material being cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 41 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\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: C46120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697073717554,"sku":"C46120","price":73.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96fe46cb89dab19aea99fd691a6ace5c.jpg?v=1788349079","url":"https:\/\/voomisupply.com\/products\/cleveland-c46120-countersink-5-8-in-82-degree-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
