The tool features a 1\/8-inch head diameter and a 90-degree included angle, making it suited for producing clean, accurate countersunk profiles in a variety of workpiece materials. With a 1\/8-inch shank diameter and an overall length of 1.5 inches (38 mm), this is a compact tool built for tight-clearance applications where control and precision matter. Machinists, toolmakers, and fabricators working on small-diameter fastener seats or edge prep operations will find this tool fits standard 1\/8-inch collet and chuck setups.\u003c\/p\u003e\n\u003cp\u003eThis countersink is appropriate for use in manual mills, CNC machining centers, drill presses, and hand-held pneumatic or electric spindle tools where a 1\/8-inch shank is accepted. It is well suited for deburring small-diameter drilled holes, creating fastener lead-ins, and chamfering edges on metal, composite, or plastic components. The single-flute geometry provides clean chip evacuation and reduces chatter in precise, low-feed finishing passes. This tool is commonly used in aerospace, automotive, and general metalworking shops handling small-scale or detail work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life and wear resistance\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle suits standard fastener countersink profiles\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design promotes clean chip flow and reduces vibration\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch head diameter and 1\/8-inch shank for compact, tight-clearance use\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.5 inches supports use in confined workholding setups\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 for use in any spindle, collet, or chuck accepting a 1\/8-inch shank.

Before changing or setting the tool, ensure the spindle is fully stopped and the machine is in a safe, locked-out state per applicable shop safety procedures. Secure the shank firmly in the collet or chuck to the manufacturer-specified clamping method to prevent pullout during operation. Use appropriate cutting speeds and feeds for the workpiece material  -  do not force the tool or use it as a drill to start holes from solid stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.125 inches (3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 0.125 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\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountersink Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Chamfering, Countersinking, Deburring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: KEO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 919-000-949\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51997789126962,"sku":"919-000-949","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35edf4455b638c0acad996d220705d3b.jpg?v=1789994376","url":"https:\/\/voomisupply.com\/products\/keo-919-000-949-carbide-countersink-1-8-in-90-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
