With a 9\/16 inch head diameter and a 1\/2 inch shank diameter, this pilot locates the counterbore cutter concentrically over a pre-drilled hole, ensuring accurate depth and alignment. Constructed from carbon steel with a bright, uncoated finish, it delivers adequate hardness for general-purpose metalworking and fabrication tasks. Machinists, tool and die workers, and maintenance technicians use counterbore pilots when preparing bolt or cap screw seats in metal components.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is suited for use in machine shops, manufacturing facilities, and industrial maintenance environments where counterbored holes are required for socket head cap screws or similar fasteners. It fits into standard counterbore tool bodies that accept a 1\/2 inch shank pilot and pairs with a cutter sized for a 9\/16 inch head diameter. Typical applications include preparing mounting surfaces in steel plate, structural components, and equipment housings where flush or recessed fastener installation is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16 inch head diameter for accurate cutter alignment on standard counterbore sizes\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter for secure seating in compatible counterbore tool bodies\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides durability for general metalworking applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows visual inspection of pilot condition before use\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.19 pounds, easy to handle and swap during tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or spare counterbore pilot for standard counterbore tool bodies that accept a 1\/2 inch shank diameter pilot with a 9\/16 inch head diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or maintenance technicians. Ensure the machine spindle is fully stopped and power is disconnected before inserting or removing the pilot from the counterbore tool body. Verify that the pilot shank fits securely and without play in the counterbore body before initiating a cut. Follow applicable shop safety standards and manufacturer guidelines for speeds and feeds when operating counterboring tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 08909368\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689594716466,"sku":"08909368","price":28.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b24651bd0c8f03944e5d958e5d458425.jpg?v=1788261581","url":"https:\/\/voomisupply.com\/products\/value-collection-08909368-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
