It features a 5\/8-inch head diameter, an 82-degree included angle, and 6 flutes that support clean, accurate material removal with reduced chatter. The solid carbide construction provides the hardness and wear resistance required for production use on ferrous and non-ferrous materials. The 3\/8-inch shank diameter fits standard drill chucks and collet holders, making it straightforward to mount in most machining setups. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for chamfering drilled holes, preparing fastener seats, and deburring edges in shop and production environments. The 82-degree included angle accommodates common flat-head fastener specifications used in aerospace, automotive, and general manufacturing applications. With a 2.75-inch overall length and a 5\/8-inch maximum cutting diameter, it handles typical countersinking tasks on workpieces held in milling machines, drill presses, or CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high wear resistance and long tool life\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle suits common flat-head fastener seat geometries\u003c\/li\u003e\n  \u003cli\u003e6-flute design promotes smooth cutting action and reduced chatter\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch maximum cutting diameter handles a wide range of hole sizes\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank fits standard collet holders and drill chucks\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-end countersink compatible with standard 3\/8-inch collet holders, drill chucks, and tool holders used in drill presses, milling machines, and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling professionals. Secure the 3\/8-inch shank firmly in a collet or chuck before operation and verify runout is within acceptable limits for the application. Power down and de-energize the machine before changing tooling. Do not exceed the recommended spindle speeds for carbide tooling in the specific workpiece material.\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 inches (0.6250 inches \/ 15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 5\/8 inches\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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\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\u003eMaterial\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: 0.11 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: 919-001-022\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":51972908810546,"sku":"919-001-022","price":126.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd8de4f4826434cce036a9e90210c03.jpg?v=1789971181","url":"https:\/\/voomisupply.com\/products\/keo-919-001-022-countersink-5-8-in-82-degree-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
