Built from cobalt steel, this tool handles harder materials and elevated cutting temperatures better than standard high-speed steel. It features a straight-cylindrical shank measuring 0.437 inches in diameter and cuts in the forward direction with 3 flutes for efficient chip evacuation. At an overall length of approximately 5 inches (127 mm), it fits standard drill press chucks and milling machine setups used in machining and fabrication shops.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is suited for metalworking applications where a 6 mm fastener must be recessed into a workpiece. It is compatible with M6 fasteners and maintains a 6.6 mm pilot diameter to self-locate in a pre-drilled clearance hole. Typical use cases include production machining, maintenance repair, and toolroom work on steel, stainless, cast iron, and other ferrous materials where cobalt-grade tooling provides better wear resistance than standard HSS.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for improved heat and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e11 mm counterbore diameter seats M6 socket-head fasteners\u003c\/li\u003e\n  \u003cli\u003e6.6 mm pilot diameter self-locates in pre-drilled clearance holes\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry promotes chip clearance and stable cutting\u003c\/li\u003e\n  \u003cli\u003e0.437-inch straight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eForward cutting direction for use in conventional drill press and milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M6 fasteners (6 mm fastener size compatibility) in drill press, vertical mill, or hand-drill applications where a straight-cylindrical shank is accepted.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or experienced metalworker should install and operate this tool following standard machine-shop safety practices. Secure the workpiece firmly before cutting, and ensure the spindle speed is appropriate for the workpiece material and tool diameter. Pilot the counterbore into a pre-drilled clearance hole to prevent walking and maintain concentricity. Apply cutting fluid when working with stainless steel or other hard ferrous alloys to extend tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 6.6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Size Compatibility\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 127 mm (approximately 5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\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: E1419006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694026785074,"sku":"E1419006","price":54.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2713f8c3a90b184e3c0e0b7739276fe4.jpg?v=1788319614","url":"https:\/\/voomisupply.com\/products\/value-collection-e1419006-solid-pilot-counterbore-11mm","provider":"Voomi Supply","version":"1.0","type":"link"}
