It features a 90-degree included angle and a 1\/2-inch head diameter, making it suited for standard fastener seating applications. The straight-cylindrical shank measures 1\/4 inch in diameter, and the tool has an overall length of 2.875 inches. Solid carbide construction delivers hardness and wear resistance beyond high-speed steel, supporting use in abrasive and difficult-to-machine workpiece materials. Machinists, toolmakers, and CNC operators working in production or job shop environments are the primary installers and users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is applicable across a broad spectrum of materials including steel, stainless steel, cast iron, titanium, high-temperature alloys, non-ferrous metals, composites, and plastics. The single-flute design reduces cutting forces and improves surface finish in harder materials where chatter can be a concern. It is used in machine shop, aerospace, and general metalworking setups where consistent countersink geometry is required for flathead fastener installations or deburring operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle for standard flathead fastener seating\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch maximum cutting diameter with 1\/4-inch straight-cylindrical shank\u003c\/li\u003e\n  \u003cli\u003eSingle-flute geometry reduces cutting forces and minimizes chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eNo pilot required — single-end design for direct machine spindle mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for countersinking operations in steel, stainless steel, cast iron, titanium, high-temperature alloys, non-ferrous metals, composites, and plastics. The 1\/4-inch straight-cylindrical shank fits standard collets and drill chucks that accept that shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists and CNC operators using standard drill press, milling machine, or lathe setups. Secure the 1\/4-inch shank in a properly sized collet or drill chuck before operation and verify runout is within acceptable tolerances for the application. Use appropriate cutting speeds and feeds for the workpiece material — solid carbide tooling generally runs at higher speeds than high-speed steel but is sensitive to interrupted cuts and side-loading. Always follow applicable machine safety protocols and wear appropriate eye protection during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.875 inches\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 Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountersink Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Material\u003c\/strong\u003e: Steel\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74213\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51728328458546,"sku":"74213","price":78.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca73cf07e6bef434ae641a450514610d.jpg?v=1788690486","url":"https:\/\/voomisupply.com\/products\/sgs-74213-countersink-1-2-in-90-degree-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
