With a 5\/8 inch head diameter, an 82-degree included angle, and a 3\/8 inch shank diameter, this tool delivers clean, accurate cone-form cuts in a single pass. The solid carbide construction provides the hardness and wear resistance needed for production use on ferrous and non-ferrous materials. Machinists and tool-and-die professionals rely on this style of countersink for consistent results in drilling programs and manual mill setups alike.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for light industrial and precision machining applications where a controlled 82-degree included angle is required  -  common in aerospace fastener prep, sheet metal work, and general manufacturing. The single-flute design reduces chatter and is well-suited for hand-held power tool use as well as machine spindle mounting. The 2.75 inch overall length accommodates standard chuck depths without requiring an extension.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life and resistance to heat buildup\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle for standard fastener seat preparation\u003c\/li\u003e\n  \u003cli\u003eSingle flute reduces chatter and improves surface finish in the cut zone\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch maximum cutting diameter suits a wide range of fastener head sizes\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter compatible with common drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eSuitable for chamfering, countersinking, and deburring in one tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in CNC machining centers, drill presses, and hand-held power tools accepting a 3\/8 inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this countersink is performed by licensed machinists or qualified shop personnel. Secure the 3\/8 inch shank firmly in a collet or drill chuck before operation and verify runout before cutting. Power down and de-energize the machine spindle before tool changes. Do not exceed the recommended feed and speed ratings for solid carbide tooling in the material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\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: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches (70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\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: 0.1 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: 919-000-939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":52059051065650,"sku":"919-000-939","price":112.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/144f1d63c00d55900ffbb473bd5a8722.jpg?v=1790040099","url":"https:\/\/voomisupply.com\/products\/keo-919-000-939-countersink-5-8-in-82-degree-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
