The pilot features a 0.5 inch head diameter and a 0.25 inch shank diameter, making it suited for use in standard counterbore tool setups. Constructed from carbon steel with a bright, uncoated finish, this pilot delivers reliable performance in light to medium-duty machining environments. Machinists and tool-and-die professionals install this type of pilot to maintain concentricity between a drilled hole and its counterbore, reducing runout and improving seat quality on fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is appropriate for use in manual mills, drill presses, and CNC machining centers where precise counterbore alignment is required. It is commonly used in fabrication shops, maintenance facilities, and production machining operations. The 0.25 inch shank diameter fits standard counterbore bodies designed for that shank size. Typical applications include creating flat-bottomed recesses for socket head cap screws and similar fasteners in metal workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5 inch head diameter for proper counterbore seat engagement\u003c\/li\u003e\n  \u003cli\u003e0.25 inch shank diameter fits standard counterbore tool bodies\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction for light to medium-duty machining use\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for straightforward inspection and measurement\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.12 pounds for easy handling and storage\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 sets and bodies accepting a 0.25 inch shank diameter pilot with a 0.5 inch head diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists as part of a counterbore tool assembly. Before installing or changing pilots, ensure the machine is fully powered down and the spindle is at a complete stop. The pilot should be seated securely in the counterbore body per the tool manufacturer guidelines before beginning any cutting operation. Follow applicable shop safety procedures and wear appropriate eye protection when operating cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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: 08905325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694129021234,"sku":"08905325","price":20.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7fb2db36e6ecd091bacc4710a6d4f2d1.jpg?v=1788320659","url":"https:\/\/voomisupply.com\/products\/value-collection-08905325-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
