Built from high speed steel with a bright, uncoated finish, this tool delivers consistent cutting performance in production and maintenance machining environments. The counterbore measures 2.375 inches in diameter with a 1.75-inch straight shank and a 9.875-inch overall length. Right-hand cutting geometry suits standard drill press and milling machine setups. The interchangeable pilot design accepts a 0.5-inch pilot shank, allowing the tool to be reused across different pilot sizes without replacing the entire body.\u003c\/p\u003e\u003cp\u003eThis counterbore is suited for machining operations that require a flat-bottomed recess to seat socket head cap screws, hex bolts, or similar fastener heads flush or below a workpiece surface. Typical applications include fabrication shops, aerospace maintenance facilities, and general metalworking operations where consistent recess depth and diameter are required. The 5-flute configuration reduces chatter and improves surface finish in ferrous and non-ferrous materials at moderate feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.375-inch counterbore diameter for large-fastener recess applications\u003c\/li\u003e\n\u003cli\u003e5-flute design reduces chatter and improves finish quality\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eInterchangeable pilot accepts 0.5-inch pilot shank for flexible setup\u003c\/li\u003e\n\u003cli\u003e1.75-inch straight shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows visual wear monitoring during use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style interchangeable pilot counterbore compatible with standard straight-shank toolholders and drill press chucks sized for a 1.75-inch shank diameter, accepting a 0.5-inch interchangeable pilot.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this counterbore should be performed by a qualified machinist or tooling professional. Secure the straight shank firmly in a properly sized collet or drill chuck before operation, and verify pilot fit before engaging the workpiece. Power down and lock out the machine before changing pilots or inspecting the cutting edges. Do not exceed the spindle speed recommended for the workpiece material and tool diameter to avoid premature wear or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 7.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Shank Diameter Compatibility\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated, Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAircraft Style\u003c\/strong\u003e: No\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: GH8792244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697272946994,"sku":"GH8792244","price":953.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8373f0fd7dbb88579b3c71d4c2522b3c_4eff76e1-e557-467c-b860-e5a991834f02.jpg?v=1788351020","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8792244-counterbore-5-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
