If the counterbored portion is shallow (1\/8\" or less), the operations is usually known as spot-facing; for example, a flat seat for a bolt head or nut. If, on the other hand, the hole is enlarged to a considerable depth, it is designated as counterboring. These counterbores are made of two-piece construction, having an integral shank and counterbore-cutter, and a pilot that is interchangable, which provides flexibility in the use of the tool.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eBrand \u003c\/strong\u003eDrill America\u003cbr\u003e\u003cstrong\u003ePart Number \u003c\/strong\u003eDEWCBRTS1INCH\u003cbr\u003e\u003cstrong\u003eBody Dia \u003c\/strong\u003e1\"\u003cbr\u003e\u003cstrong\u003eMaterial \u003c\/strong\u003eHigh Speed Steel\u003cbr\u003e\u003cstrong\u003ePilot Dia \u003c\/strong\u003e5\/16\"\u003cbr\u003e\u003cstrong\u003eShank Size \u003c\/strong\u003e3MT\u003cbr\u003e\u003cstrong\u003eShank Type \u003c\/strong\u003eTaper\u003cbr\u003e\u003cstrong\u003eFinish \u003c\/strong\u003eUncoated (Bright)\u003cbr\u003e\u003cstrong\u003eNumber of Flutes \u003c\/strong\u003e3\u003cbr\u003e\u003cstrong\u003eLength \u003c\/strong\u003e6-3\/8\"\u003cbr\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"BoltsandNuts.com","offers":[{"title":"1","offer_id":51560535490845,"sku":"BIT-DEWCBRTS1INCH","price":73.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/9517\/5197\/files\/DEWCBRTS34-MAIN_d7d3fb41-40c2-4ff0-92c6-9efae303a1b6.jpg?v=1780097491","url":"https:\/\/industrialwarehouse.com\/products\/1-x-5-16-pilot-hole-hss-taper-shank-counterbore","provider":"Industrial Warehouse","version":"1.0","type":"link"}
