The pilot features a 5\/8 inch head diameter and a 3\/16 inch shank diameter, making it suited for maintaining concentricity when enlarging or finishing bored holes. Constructed from carbon steel with a bright uncoated finish, this pilot delivers reliable rigidity for general machining applications. It is installed by machinists and tool-and-die professionals working on lathes, drill presses, or milling machines where accurate hole alignment is critical.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is appropriate for light to medium-duty machining tasks in both shop and maintenance environments. It fits into standard counterboring tool bodies that accept a 3\/16 inch shank and is commonly used when producing counterbored holes for fastener seating in metal fabrication, mechanical assembly, and repair work. The bright uncoated finish is suitable for dry or lightly lubricated cutting conditions on ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch head diameter for accurate counterbore guidance\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch shank diameter for secure seating in compatible counterbore bodies\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides adequate rigidity for general machining\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for standard shop cutting conditions\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.12 pounds for easy handling and tool changes\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 tool bodies accepting a 3\/16 inch shank diameter with a 5\/8 inch pilot head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or maintenance technicians. Ensure the machine spindle is fully powered down and locked out before inserting or removing the pilot from the counterbore body. Seat the shank fully and verify it is secure before resuming any cutting operation. Apply appropriate cutting fluid or lubricant as required by the workpiece material to extend pilot service life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/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: 0.12 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: 08904401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709743104306,"sku":"08904401","price":27.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b0e14896d2b304e780fbee6c748a4fc.jpg?v=1788459883","url":"https:\/\/voomisupply.com\/products\/value-collection-08904401-counterbore-pilot-5-8-in-head","provider":"Voomi Supply","version":"1.0","type":"link"}
