The pilot features a 1-1\/16 inch head diameter and a 1\/2 inch shank diameter, providing a stable interface between the cutting tool and the workpiece. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general-purpose metalworking and machining applications. Machinists and tool-and-die professionals install this type of pilot to maintain concentricity when enlarging or finishing a bored hole to accept a fastener head or bearing seat.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is appropriate for use in manual and CNC machining environments where accurate hole alignment is required. It fits into standard counterboring tool holders that accept a 1\/2 inch shank. Typical applications include fabrication shops, maintenance and repair operations, and production machining where consistent hole geometry is critical. The bright finish indicates no additional heat treatment or coating, making it best suited for non-corrosive environments or situations where lubrication is applied at the point of cut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/16 inch head diameter for proper counterbore sizing\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter for standard tool holder compatibility\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides adequate rigidity for general-purpose machining\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows for visual inspection and easy dimensional verification\u003c\/li\u003e\n  \u003cli\u003eGuides the counterboring cutter to maintain hole concentricity\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 counterboring tools that accept a 1\/2 inch shank pilot.

Before inserting or removing the pilot, power down and lock out the machine per standard lockout\/tagout procedures. Ensure the pilot shank is clean and free of burrs before seating it in the counterbore tool to avoid runout. Do not exceed the cutting tool manufacturer's recommended speeds and feeds for the associated counterboring operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\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: 0.43 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: 08909681\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708868198706,"sku":"08909681","price":37.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba242f7c137908025652cc8ee00dabcf_c58f727c-2e6e-4ac5-b1f1-dd8fcc95d557.jpg?v=1788448798","url":"https:\/\/voomisupply.com\/products\/value-collection-08909681-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
