The pilot fits a 3\/8 inch shank diameter and supports a 11\/16 inch head diameter, keeping the cutter centered over a pre-drilled hole. Made from carbon steel with a bright uncoated finish, this pilot is suited for general-purpose machine shop and maintenance work. It is installed by machinists, tool and die workers, and maintenance technicians performing precision hole finishing on ferrous and mild non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis counterbore pilot is designed for use in drill press, milling machine, and hand-drilling applications where a flat-bottomed recess is required for fastener seating. The 3\/8 inch shank diameter matches standard counterbore sets and arbors commonly found in production and repair environments. It is appropriate for light to moderate duty material removal on steel and similar workpieces in both shop and field maintenance settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/16 inch head diameter for accurate counterbore alignment\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter fits standard counterbore arbors and tool holders\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction suitable for general machining applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for straightforward visual inspection and measurement\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.15 pounds for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or supplemental pilot for standard counterbore sets using a 3\/8 inch shank diameter arbor in general machining and maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using standard counterbore tooling. Ensure the machine spindle is fully powered down and locked out before changing or seating the pilot. The pilot should slide snugly into the counterbore arbor bore without excessive play to maintain concentricity during cutting. Verify shank and head diameter compatibility with the counterbore set before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/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: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 08907446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716421615922,"sku":"08907446","price":24.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6f29f81f92394373cbe0dff401341e6.jpg?v=1788525846","url":"https:\/\/voomisupply.com\/products\/value-collection-08907446-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
