It features a 1-1\/4 inch head diameter, a 90-degree included angle, and a 3\/4 inch shank diameter, giving it a rigid, precise profile suited for production and toolroom use. The solid carbide construction delivers superior hardness and wear resistance compared to high-speed steel alternatives, making it well suited for harder workpiece materials and extended run cycles. Overall length is 3.25 inches, and the tool weighs 0.33 pounds.\u003c\/p\u003e\n\u003cp\u003eThis countersink is intended for use in drill presses, CNC machining centers, and manual mills where a clean, consistent chamfer or countersink profile is required. The 90-degree included angle accommodates standard fastener-seat geometry common in aerospace, automotive, and general metalworking fabrication. The single-flute design reduces chatter and produces a smooth surface finish on the entry cut. It is typically installed and operated by machinists and tool-and-die professionals working with ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life and high wear resistance\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle suits standard countersunk fastener geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch maximum cutting diameter handles larger fastener seat profiles\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch shank diameter provides secure, rigid toolholder engagement\u003c\/li\u003e\n  \u003cli\u003eSuitable for chamfering, countersinking, and deburring in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style single-flute carbide countersink compatible with standard toolholders and collet chucks accepting a 3\/4 inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists. Secure the 3\/4 inch shank firmly in a collet chuck or end mill holder rated for the shank diameter before use. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Carbide tooling is brittle and should not be dropped or subjected to side impacts during handling or storage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches (83 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Chamfering, Countersinking, Deburring\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: KEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 919-000-965\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51990319890738,"sku":"919-000-965","price":399.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5995fa3a97d0a543739ebf83fdf81c14.jpg?v=1789988850","url":"https:\/\/voomisupply.com\/products\/keo-919-000-965-countersink-1-1-4-in-90-deg-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
