This double-end tool performs drilling and countersinking in a single pass, reducing tool changes and setup time on the bench or machine. It features a 120-degree drill point angle and a 60-degree included angle with a radius cutting edge style, making it suitable for deburring, chamfering, and countersinking operations on metal workpieces. Right-hand cutting direction is standard. The tool weighs approximately 0.1 pounds and is not aircraft-style or long-length configuration.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is intended for use in metalworking and machining environments where metric tooling is required. The double-end design extends usable tool life. With a body diameter of 4.00 mm, a drill point diameter of 1.60 mm, and an overall length of 35.50 mm, it fits standard toolholders used in drill presses, lathes, and CNC setups. Machinists, tool-and-die workers, and general metalworking professionals are the primary installers and users of this tool type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design for extended tool life and fewer changeovers\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across common metalworking materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose countersinking\u003c\/li\u003e\n\u003cli\u003e120-degree drill point angle with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRadius cutting edge style for smooth countersink profile\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, standard machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose metric combo drill countersink suitable for use in standard drill presses, lathes, and CNC machining centers that accept toolholders sized for 4.00 mm body diameter tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists and metalworking professionals. Secure the tool firmly in a compatible toolholder or chuck before operation and verify spindle speed is appropriate for the workpiece material and tool diameter. Always power down the machine completely before inserting or removing the tool. Do not exceed the tool's rated cutting parameters for the workpiece material to avoid tool breakage or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 1.60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 4.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 35.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRadius Length\u003c\/strong\u003e: 5.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 906-000-385\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51973902008626,"sku":"906-000-385","price":22.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee9a4454ed05a3c592e04532a8e2cd8b.jpg?v=1789974978","url":"https:\/\/voomisupply.com\/products\/keo-906-000-385-combo-drill-countersink-metric-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
