The pilot fits into a drilled hole and centers the counterbore cutter, ensuring accurate seat depth and concentricity. It features an 11\/32-inch head diameter and a 5\/32-inch shank diameter, machined from carbon steel with a bright, uncoated finish. This type of pilot is a standard consumable in machine shops, maintenance facilities, and manufacturing environments where fastener seating requires clean, repeatable counterbore geometry.\u003c\/p\u003e\u003cp\u003eCounterbore pilots are used in metalworking and light fabrication applications where socket head cap screws or similar fasteners must sit flush or below a workpiece surface. The 5\/32-inch shank diameter determines the pilot bore size this tool is suited for, making it appropriate for small-diameter counterbore sets. It is typically used with a matching counterbore body in manual or CNC milling setups, drill presses, or hand-held power tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/32-inch head diameter for proper counterbore seat engagement\u003c\/li\u003e\n\u003cli\u003e5\/32-inch shank diameter for precise pilot hole alignment\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction for durability in general machining applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for standard shop use\u003c\/li\u003e\n\u003cli\u003eSold individually, compatible with standard interchangeable counterbore systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pilot for standard interchangeable counterbore cutter sets requiring a 5\/32-inch shank pilot.

Always secure the workpiece and power down the machine before changing pilots. Inspect the pilot for wear or damage before each use, as a worn pilot will compromise counterbore concentricity. Follow standard shop safety practices and applicable facility procedures when operating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 11\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 08903221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722404004146,"sku":"08903221","price":20.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/320018adc9e3cd75e70ffaaf6fc5cc2b.jpg?v=1788590596","url":"https:\/\/voomisupply.com\/products\/value-collection-08903221-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
