Built from high speed steel with a bright, uncoated finish, this tool features a 9\/16 inch counterbore diameter and a 1\/2 inch straight shank. With an overall length of 4-5\/16 inches and a right-hand cutting direction, it is suited for use in drill presses, milling machines, and hand-held power equipment where a clean, flat-bottomed seat is required around a drilled hole. The interchangeable pilot design allows the pilot to be swapped to match the fastener or hole size being worked.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is intended for use in general metalworking, maintenance, and repair environments where socket head cap screws or similar fasteners must be recessed flush or below a workpiece surface. It is compatible with a 3\/16 inch pilot shank diameter, making it appropriate for standard fastener seating applications in ferrous and non-ferrous metals. Machinists, tool-and-die technicians, and maintenance mechanics working in industrial or job-shop settings are the typical end users for this type of tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16 inch counterbore diameter for precise flat-bottomed seat creation\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry for smooth cutting action and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across a range of metal workpieces\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch straight shank for broad compatibility with standard chucks and holders\u003c\/li\u003e\n  \u003cli\u003eInterchangeable pilot accepts 3\/16 inch pilot shank for versatile fastener sizing\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose machining without added coating wear considerations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose interchangeable pilot counterbore compatible with standard 1\/2 inch straight-shank tool holders and accepts a 3\/16 inch interchangeable pilot shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is typically installed by machinists or maintenance technicians using a standard drill press, mill, or hand-held power drill with a compatible 1\/2 inch chuck. Secure the straight shank firmly in the chuck before operation and confirm the interchangeable pilot is properly seated before beginning the cut. Always power down and de-energize the machine before changing pilots or removing the tool. Follow applicable shop safety standards and manufacturer guidelines for feed rate and spindle speed appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Shank Diameter Compatibility\u003c\/strong\u003e: 3\/16 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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\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: GH8790362\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723588469042,"sku":"GH8790362","price":80.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/940d71c56acf57137fe57e5b4766dee6.jpg?v=1788606779","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8790362-counterbore-9-16-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
