Built from cobalt steel, this tool offers increased heat and wear resistance compared to standard high-speed steel, making it suitable for drilling harder ferrous materials. It features a straight-cylindrical shank measuring 0.5 inches (12.70 mm) in diameter and an overall length of 6 inches (152.4 mm). The 18 mm cutting diameter paired with an 11 mm pilot provides accurate centering and a clean seating surface. Machinists and tool-and-die professionals typically install this in a milling machine, drill press, or lathe for cap-screw and socket-head fastener seat preparation.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is sized for use with 10 mm fasteners, producing an 18 mm diameter seat. It is suited for forward-cutting applications in ferrous and alloy metals where cobalt steel tooling is preferred for extended tool life. The straight-cylindrical shank fits standard drill chucks and collet systems accepting a 0.5-inch shank, making it compatible with a wide range of shop and production machine setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction provides superior heat resistance and durability over standard HSS tooling\u003c\/li\u003e\n  \u003cli\u003e18 mm counterbore diameter seats 10 mm fasteners with precision clearance\u003c\/li\u003e\n  \u003cli\u003e11 mm solid pilot ensures accurate centering in pre-drilled holes\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 0.5-inch shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eForward cutting direction compatible with conventional machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style solid pilot counterbore for machining operations requiring a 10 mm fastener seat with an 18 mm diameter bore, using any machine tool equipped with a 0.5-inch straight-cylindrical shank chuck or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists in milling machines, drill presses, or lathes equipped with a compatible chuck or collet. Secure the shank firmly before operation and verify the pilot fits the pre-drilled hole without excessive play. Apply appropriate cutting fluid for the workpiece material to extend tool life and reduce heat buildup. Always power down and lock out the machine before changing tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Size Compatibility\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Forward\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E1419010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712259817778,"sku":"E1419010","price":64.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53076925c98d225649d93bc4fcfcf5c1.jpg?v=1788485731","url":"https:\/\/voomisupply.com\/products\/value-collection-e1419010-solid-pilot-counterbore-18mm","provider":"Voomi Supply","version":"1.0","type":"link"}
