{"product_id":"value-collection-08902249-counterbore-pilot-carbon-steel","title":"Value Collection 08902249 Counterbore Pilot Carbon Steel","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe VALUE COLLECTION 08902249 is a counterbore pilot used to guide counterboring tools during precision machining and fastener seat preparation. The pilot registers in a pre-drilled hole to keep the counterbore tool centered and running true. It features a 3\/8 inch head diameter and a 1\/8 inch shank diameter, making it suited for small-bore counterboring work. The body is machined from carbon steel with a bright, uncoated finish. Machinists, tool and die technicians, and maintenance mechanics install this type of pilot when preparing bolt-seat counterbores in metal workpieces requiring consistent depth and concentricity.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is used in light fabrication shops, maintenance repair operations, and production machining environments. It is appropriate for applications where a 1\/8 inch shank pilot is needed to guide a counterbore cutter producing a 3\/8 inch head-diameter seat. Typical use cases include preparing counterbored holes for socket head cap screws and similar fasteners in steel, aluminum, or other machinable materials. The bright uncoated finish is standard for general-purpose shop use where coating is not required by the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch head diameter for accurate counterbore seat sizing\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank diameter for pilot-hole registration and tool centering\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides adequate hardness for general machining applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suited for dry or lightly lubricated cutting conditions\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece design with no moving parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard counterbore pilot for use with compatible counterboring tools requiring a 1\/8 inch shank pilot and a 3\/8 inch head diameter seating surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a drill press, milling machine, or hand-held drilling equipment. Ensure the pilot hole is clean and correctly sized before inserting the pilot to avoid runout or tool damage. Secure the counterbore body according to the tool manufacturer's instructions before beginning the cut. Always wear appropriate eye protection and follow shop safety procedures when operating rotating 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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 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: 0.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\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: 08902249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694188560690,"sku":"08902249","price":18.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bab2875eb9aefca8eab46007f62a40ba.jpg?v=1788321459","url":"https:\/\/voomisupply.com\/products\/value-collection-08902249-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
