The pilot seats into the counterbore tool shank and centers the cutter over a pre-drilled hole, producing clean, concentric counterbored seats for socket head cap screws and similar fasteners. Constructed from carbon steel with a bright, uncoated finish, this pilot features a 7\/16 inch head diameter and a 1\/4 inch shank diameter. Machinists, tool-and-die workers, and maintenance technicians install this type of pilot when setting up manual or CNC machine tools for counterboring work.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is suited for use in general metalworking, maintenance, and fabrication shops where standard counterbore setups are required. The 1\/4 inch shank diameter fits counterbore holders designed for that shank size, making it a common replacement or spare pilot for bench-top drill presses and milling setups. It is appropriate for light-duty to medium-duty counterboring applications in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16 inch head diameter for precise counterbore centering\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank diameter for compatibility with standard counterbore holders\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction for durability in general machining applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for easy inspection and corrosion monitoring\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.12 pounds for easy tool-change handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or spare pilot for counterbore sets and holders accepting a 1\/4 inch shank diameter pilot with a 7\/16 inch head diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians as part of counterbore tool setup. Ensure the machine spindle is fully de-energized and the tool holder is secured before inserting or removing the pilot. The pilot should seat firmly in the counterbore body with no lateral play before beginning the cut. Follow applicable shop safety procedures and machine manufacturer guidelines during tool changes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: 08905283\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689066922290,"sku":"08905283","price":19.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/555c327fc4e9d393c61d8684b52735bc.jpg?v=1788254408","url":"https:\/\/voomisupply.com\/products\/value-collection-08905283-counterbore-pilot-7-16-in-head","provider":"Voomi Supply","version":"1.0","type":"link"}
