The pilot seats into a pre-drilled hole and centers the counterbore cutter, ensuring a flat-bottomed recess is cut concentrically with the existing bore. It features an 11\/16 inch head diameter and a 5\/16 inch shank diameter. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general-purpose shop work on ferrous and non-ferrous materials. Machinists, tool and die technicians, and maintenance mechanics are the typical users.\u003c\/p\u003e\u003cp\u003eThis counterbore pilot is appropriate for use in machine shops, maintenance facilities, and fabrication environments where counterboring operations are performed on drill presses, milling machines, or manual equipment. It is used to create recesses for socket head cap screws, button head fasteners, and similar hardware requiring a flat-seated bearing surface. The 5\/16 inch shank diameter fits standard counterbore holders designed for that shank size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/16 inch head diameter for accurate recess sizing\u003c\/li\u003e\n\u003cli\u003e5\/16 inch shank diameter for standard tool holder compatibility\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction provides adequate hardness for general-purpose machining\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows visual inspection of tool condition\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.15 pounds for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard pilot for counterbore tool sets accepting a 5\/16 inch shank diameter pilot.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using standard counterbore holders compatible with a 5\/16 inch shank. Secure the pilot firmly in the holder before beginning any cutting operation and verify the pilot fits the pilot hole without excessive play. Always power down and lock out the machine spindle before changing or seating pilots. Follow applicable shop safety procedures and applicable OSHA machining standards when operating counterboring equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 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: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 08906448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691384013106,"sku":"08906448","price":27.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6e13dac321aafabe3fd19da55fba3aa.jpg?v=1788284256","url":"https:\/\/voomisupply.com\/products\/value-collection-08906448-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
