The pilot centers the cutting tool over a pre-drilled hole to ensure accurate, concentric counterbores in metal workpieces. It features a 0.625-inch head diameter and a 0.5-inch shank diameter, constructed from bright, uncoated carbon steel for solid performance in general-purpose shop environments. Machinists and toolroom technicians install this pilot when precision alignment is required for socket head cap screw recesses and similar counterbore applications.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is suited for use in machine shops, maintenance facilities, and production environments where counterboring operations are performed on ferrous and compatible non-ferrous materials. It is typically used with interchangeable counterbore sets where the pilot and cutter are separate components, allowing one cutter body to accept multiple pilot sizes depending on hole diameter requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.625-inch head diameter for precise counterbore alignment\u003c\/li\u003e\n  \u003cli\u003e0.5-inch shank diameter for standard tool body compatibility\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction for general-purpose machining durability\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for straightforward inspection and dimensional verification\u003c\/li\u003e\n  \u003cli\u003eInterchangeable pilot design compatible with modular counterbore systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental pilot for interchangeable counterbore tool systems that accept a 0.5-inch shank diameter pilot.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians as part of counterbore setup. Ensure the machine spindle is fully powered down and at rest before inserting or removing the pilot. The pilot should seat securely in the counterbore body before initiating any cutting operation. Verify pilot fit and concentricity before beginning the counterboring pass to prevent tool walkout or hole misalignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 08909400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698960761138,"sku":"08909400","price":27.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abe33f23016a099cd564838a56a1f51d.jpg?v=1788370394","url":"https:\/\/voomisupply.com\/products\/value-collection-08909400-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
