With a 1-inch head diameter and a 90-degree included angle, this tool produces a 45-degree centerline angle per side, making it well-suited for deburring drilled holes and seating flat-head fasteners flush with the workpiece surface. The 1\/2-inch straight-cylindrical shank fits standard drill chucks and milling machine spindles. An oxide coating provides moderate lubricity and surface protection during cutting. Licensed machinists, tool and die technicians, and maintenance trades reach for this style of countersink in high-volume metal fabrication and repair applications.\u003c\/p\u003e\n\u003cp\u003eThis countersink is rated for use in carbon steel and cast iron. The single-flute geometry produces a chatter-free finish in these materials, which is especially useful when working in harder grades of cast iron where multi-flute tools can vibrate. It is suited for bench drill press work, CNC machining centers, and manual milling operations where a 1\/2-inch toolholder or collet is available. The straight-cylindrical shank seats directly in a drill chuck without an adapter. Pilot-free design means no separate pilot is included or required; the operator centers the tool on the existing pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch head diameter for large fastener seat recesses\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle, 45-degree centerline angle per side, matches standard flat-head fastener geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design reduces chatter in carbon steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides heat resistance during dry or lubricated cutting\u003c\/li\u003e\n  \u003cli\u003eOxide finish adds surface lubricity and corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight-cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for countersinking operations in carbon steel and cast iron workpieces. Rated for use in machines accepting a 1\/2-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the workpiece firmly before operation; countersinks generate lateral cutting forces that can spin unsecured parts. Ensure the spindle is powered off and at a full stop before installing or removing the tool from the chuck. Use cutting fluid when working in harder steels to extend tool life and improve surface finish. Inspect the cutting edge for chipping before each use; a damaged flute on a single-flute tool produces an unacceptable seat finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 45 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: 0.5 inches (12.70 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\u003ePilot Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\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: C46132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51721048588594,"sku":"C46132","price":145.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b46eadd5c04ff7085752878c4064f60d.jpg?v=1788572790","url":"https:\/\/voomisupply.com\/products\/cleveland-c46132-countersink-1-in-90-degree-hss-single-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
