The pilot fits into a pre-drilled hole and aligns the counterbore cutter so the recess seats concentrically with the fastener bore. It features a 9\/32-inch head diameter and a 3\/16-inch shank diameter. Constructed from carbon steel with a bright, uncoated finish, this pilot delivers adequate hardness and dimensional accuracy for light to medium machining tasks in metal, wood, and composite materials. Machinists and maintenance technicians install this type of tool in drill presses, milling machines, and hand-held power drills.\u003c\/p\u003e\n\u003cp\u003eCounterbore pilots are used wherever a flat-bottomed recess is needed to seat socket-head cap screws, bolts, or other fasteners flush with or below a workpiece surface. This pilot is suited for shop and field applications in manufacturing, mechanical maintenance, HVAC equipment assembly, and general fabrication. The 3\/16-inch shank diameter is matched to the corresponding counterbore cutter body that accepts this size pilot.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/32-inch head diameter for proper counterbore alignment\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch shank diameter for secure seating in the cutter body\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction for durability in light to medium machining\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no additional coating to affect dimensional tolerance\u003c\/li\u003e\n  \u003cli\u003eSold individually — quantity of one per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or spare counterbore pilot for cutter bodies accepting a 3\/16-inch shank with a 9\/32-inch head diameter.

Secure the workpiece firmly before operation and ensure the pilot slides freely into the guide hole before engaging the cutter. Power down and de-energize any equipment being drilled or serviced before starting. Do not force-fit a pilot that does not seat cleanly, as this can cause cutter misalignment and workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 9\/32 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: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 08904187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717488542002,"sku":"08904187","price":18.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c792e79707bc94599a68431bbb85233.jpg?v=1788541371","url":"https:\/\/voomisupply.com\/products\/value-collection-08904187-counterbore-pilot-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
