With a 3\/8 inch head diameter and a 60-degree included angle, it produces precise conical recesses sized for flat-head fasteners and deburring applications. The straight cylindrical 1\/4 inch shank fits standard drill chucks and quick-change collets. An oxide finish provides basic corrosion resistance and helps with chip evacuation. Right-hand cutting geometry makes it compatible with conventional drill press and hand-drill setups. Machinists, tool and die workers, and maintenance technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for production and maintenance work in shops handling alloy tool steel and cast iron stock. It is a single-end tool with no pilot, making it adaptable for use with a drill press, milling machine, or hand drill. Typical applications include preparing holes for flat-head cap screws, deburring drilled holes, and chamfering hole entries before tapping. The 60-degree included angle is common in metric and general-purpose fastener seating work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch head diameter with 60-degree included angle for flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry for smooth cutting action and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in tool steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eOxide finish for basic corrosion resistance and chip flow\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch straight cylindrical shank fits standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, single-end design with no pilot for flexible positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy tool steel and cast iron.

Use appropriate cutting fluid or lubricant when working in tool steel or cast iron to extend tool life and improve finish quality. Inspect the cutting edges before each use and replace the tool if chipping or wear is observed. Follow applicable shop safety standards for rotating cutting tools, including eye protection and secure guarding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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 Application\u003c\/strong\u003e: Alloy Tool Steel, Cast Iron\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: C46204\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51691781980466,"sku":"C46204","price":48.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07f008a3ca82a7ae8c23a2f8392826ed.jpg?v=1788289620","url":"https:\/\/voomisupply.com\/products\/cleveland-c46204-countersink-3-8-in-60-degree-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
