Built from high speed steel with a bright, uncoated polished finish, this tool delivers consistent cutting performance in ferrous and non-ferrous materials. It features a 2MT Morse taper shank for secure, repeatable seating in compatible machine spindles. With 3 flutes and right-hand cutting direction, it produces clean, flat-bottomed counterbore seats. Overall length is 5.125 inches. This tool is intended for machinists, tool and die shops, and maintenance professionals requiring accurate counterboring on production or repair work.\u003c\/p\u003e\u003cp\u003eThis counterbore is suited for general-purpose counterboring operations in manual mills, drill presses, and CNC machines equipped with a No. 2 Morse taper spindle or adapter. The interchangeable pilot design allows the pilot to be swapped for different pilot shank diameters without replacing the body. The 3\/16-inch pilot shank diameter compatibility makes it appropriate for use with standard interchangeable pilot sets. Typical applications include creating flat-bottom recesses for socket head cap screws and similar fasteners in steel, aluminum, and cast iron workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch counterbore diameter for standard fastener recess work\u003c\/li\u003e\n\u003cli\u003e3 flutes with right-hand cutting direction for smooth material removal\u003c\/li\u003e\n\u003cli\u003eNo. 2 Morse taper (2MT) shank for rigid spindle connection\u003c\/li\u003e\n\u003cli\u003eInterchangeable pilot accepts 3\/16-inch pilot shank diameter\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across common shop materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated polished finish — no coating buildup concerns during regrind\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in machine spindles accepting a No. 2 Morse taper.

Power down and lock out the machine spindle before inserting or removing the Morse taper shank. Seat the taper fully using a proper drift and tang engagement — never force with excessive hammer blows. Confirm pilot fit and concentricity before running under power, and use appropriate cutting fluid for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Morse Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 2MT\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\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\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: GH8780405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709887086898,"sku":"GH8780405","price":87.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f78757fe9542c3031d7e04a3425bbbd.jpg?v=1788461841","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8780405-counterbore-5-8-in-3-flute-2mt","provider":"Voomi Supply","version":"1.0","type":"link"}
