Built from high speed steel with an oxide finish, it features a 3\/8 inch head diameter and a 120-degree included angle, making it well suited for standard fastener seating applications in carbon steel and cast iron. The straight cylindrical shank measures 1\/4 inch in diameter, providing positive chuck retention in standard drill presses, CNC machining centers, and hand-held power drills. Machinists, tool and die technicians, and general fabricators reach for this tool when consistent countersink geometry is required on production or maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis countersink is intended for use in carbon steel and cast iron materials. Its single-flute geometry reduces chatter and produces a smooth finish in the countersink seat, which is especially useful when working with softer ferrous materials that are prone to tool grab. Typical applications include preparing holes for flat-head fasteners, deburring drilled openings, and creating chamfered entries before tapping operations. The 120-degree included angle aligns with common flat-head screw standards used across general metalworking and fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch head diameter with a 120-degree included angle for standard flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter and promotes smooth, consistent finish\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability in ferrous material applications\u003c\/li\u003e\n  \u003cli\u003eOxide coating helps reduce friction and provides light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch straight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight hand cut geometry compatible with conventional clockwise spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in carbon steel and cast iron applications.

Secure the shank firmly in the chuck before operation and confirm spindle rotation is set to right hand before engaging the workpiece. Keep workpieces clamped or fixtured to prevent movement during cutting. Inspect the cutting edge for wear or chipping before each use, and replace the tool if edge condition has degraded to avoid poor seat geometry.\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: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 60 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: 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\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\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Cast Iron\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\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: C46112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716640014642,"sku":"C46112","price":49.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edf74d37446e2ee645198b24e721082e.jpg?v=1788529440","url":"https:\/\/voomisupply.com\/products\/cleveland-c46112-countersink-3-8-in-120-deg-1-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
