Built from cobalt high-speed steel, this tool handles tough materials including stainless steel, alloy steel, and heat-resistant alloys where standard HSS tools wear prematurely. The 1\/8-inch body diameter and 0.025-inch drill point diameter make it well-suited for small-diameter center holes. The 60-degree included angle and 118-degree drill point angle are standard specifications for countersinking operations on machined components. Overall length is 1.25 inches. This tool is installed and operated by machinists, tool-and-die workers, and maintenance professionals working with metal fabrication or precision drilling applications.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is intended for use in machining centers, drill presses, and manual lathes where center-drilling and countersinking are required before turning or between-centers work. The aircraft style designation indicates it conforms to dimensions used in aerospace and precision manufacturing workflows. The right-hand cutting direction and plain cutting edge style make it compatible with standard right-hand spindle rotation. It is appropriate for light-duty countersinking in both production and maintenance settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction for extended tool life in hard and heat-resistant materials\u003c\/li\u003e\n\u003cli\u003eCombination drill and countersink eliminates a separate tool change between operations\u003c\/li\u003e\n\u003cli\u003e60-degree included angle suits standard countersink and center-drilling applications\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for effective penetration in metal workpieces\u003c\/li\u003e\n\u003cli\u003eAircraft style geometry for precision and dimensional consistency\u003c\/li\u003e\n\u003cli\u003eDouble end type allows the tool to be reversed when one end wears, extending usable life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use combo drill countersink for standard right-hand spindle machine tools requiring a 2\/0 trade size center drill with a 1\/8-inch body diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or maintenance professionals. Secure the tool firmly in the spindle chuck or collet before engaging the workpiece, and verify spindle rotation is set to right-hand direction before starting. Always power down and de-energize the machine before changing or inspecting the tool. Follow applicable shop safety standards and manufacturer guidelines for feeds and speeds appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 2\/0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAircraft Style\u003c\/strong\u003e: Yes\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: 1 pound\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: 906-000-029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":52122345374002,"sku":"906-000-029","price":39.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d1d47e31a0c1ea55cd37d9f590d281.jpg?v=1790085252","url":"https:\/\/voomisupply.com\/products\/keo-906-000-029-combo-drill-countersink-1-8-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
