Each single-flute countersink in the set is manufactured from cobalt steel and coated with TiAlN (titanium aluminum nitride) for extended tool life in harder workpiece materials. Head diameters range from 0.25 inches to 1 inch, with a fixed included angle of 100 degrees across all five tools. The set ships in a wood storage block that keeps tools organized and protected between uses. This is a professional-grade tooling set suited for machine shops, maintenance facilities, and production environments.\u003c\/p\u003e\u003cp\u003eThis set covers a broad range of countersinking tasks in a single kit, making it practical for general metalworking shops and industrial maintenance operations. The graduated head diameters and varying overall lengths  -  1.5 inches to 2.75 inches  -  allow technicians to match the right tool to each hole size without switching to different tool families. Shank diameters range from 0.25 inches to 0.5 inches, accommodating standard drill press, lathe, or milling machine chucks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-piece set with single-flute cobalt steel countersinks in a wood storage block\u003c\/li\u003e\n\u003cli\u003eHead diameters from 0.25 inches to 1 inch for a wide range of hole sizes\u003c\/li\u003e\n\u003cli\u003e100-degree included angle on all tools for consistent chamfer geometry\u003c\/li\u003e\n\u003cli\u003eTiAlN coating improves heat and wear resistance in harder materials\u003c\/li\u003e\n\u003cli\u003eOverall lengths from 1.5 inches to 2.75 inches with shank diameters from 0.25 inches to 0.5 inches\u003c\/li\u003e\n\u003cli\u003eSuitable for chamfering, countersinking, and deburring in a single tool family\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose countersink set compatible with standard drill press, milling machine, and lathe setups that accept round shanks in the 0.25-inch to 0.5-inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCountersinks should be installed by machinists or skilled tradespeople familiar with rotary cutting tool safety. Always power down and lock out the machine before changing tooling. Secure the shank firmly in the chuck or collet before operation, and verify spindle speed is appropriate for the workpiece material and tool diameter before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Head Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Head Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Shank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Shank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Overall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Overall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Unit Type\u003c\/strong\u003e: Wood Block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\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: 919-000-041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":52085906669874,"sku":"919-000-041","price":166.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50cec183ee152bea0c0ebd23392100ef_7300106a-3379-49a3-91e9-4aadcd2d1cb9.jpg?v=1790059288","url":"https:\/\/voomisupply.com\/products\/keo-919-000-041-countersink-set-5-pc-tialn-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
