With a 9\/16 inch head diameter and a 5\/16 inch shank diameter, this pilot fits into the drill press or handheld setup to keep the counterbore centered on the workpiece. It is constructed from carbon steel with a bright, uncoated finish. Machinists, fabricators, and maintenance technicians use this type of pilot when accurate bolt-seat depth and alignment are required on metal or hard material assemblies.\u003c\/p\u003e\n\u003cp\u003eThis counterbore pilot is suited for use in machine shops, fabrication facilities, and MRO maintenance environments where consistent counterbore alignment is needed. It is a single-piece tool intended for use with a matching counterbore body. Applications include preparing bolt holes in steel plate, structural assemblies, and equipment housings where flush or recessed fastener seating is the goal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16 inch head diameter for standard counterbore cutter fitment\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch shank diameter for secure chuck or tool holder grip\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction provides adequate hardness for ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no added coating to alter dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.18 pounds for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or stock pilot for counterbore tooling sets requiring a 9\/16 inch head diameter and 5\/16 inch shank diameter pilot. Verify counterbore body pilot bore size before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and tooling technicians working with counterbore cutting sets. Ensure the drill press or milling machine is fully powered down and the spindle is locked before seating or removing the pilot. The pilot should slide snugly into the counterbore body without play — a loose fit will cause runout and an inaccurate seat. Follow applicable shop safety procedures and manufacturer guidelines for cutting speed and feed rate when running counterbore operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\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\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: 08906364\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714111078706,"sku":"08906364","price":24.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79cc6594a5866597477f562b3820ef29.jpg?v=1788496361","url":"https:\/\/voomisupply.com\/products\/value-collection-08906364-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
