Built from high speed steel with a bright, uncoated polished finish, this tool delivers clean, consistent countersinking around pre-drilled holes. The 2MT Morse taper shank provides a secure, self-centering fit in compatible taper-socket spindles. With a counterbore diameter of 3\/4 inch, a pilot shank compatibility of 1\/4 inch, and an overall length of 5-3\/8 inches, it is sized for general-purpose shop and production use. Right-hand cutting direction is standard. Installation and operation are suited to machinists, tool-and-die workers, and skilled fabricators.\u003c\/p\u003e\u003cp\u003eThis counterbore is appropriate for use in drill presses, milling machines, and manual or CNC machining centers equipped with a Number 2 Morse taper spindle. It is suited for residential and light commercial fabrication shops, maintenance and repair operations, and production environments requiring consistent bolt-seat or fastener-seat geometry. The interchangeable pilot design allows the cutting head to be paired with different pilot sizes as job requirements change, reducing tooling inventory.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch counterbore diameter for standard fastener seating applications\u003c\/li\u003e\n\u003cli\u003e3 flutes for smooth chip evacuation and reduced chatter\u003c\/li\u003e\n\u003cli\u003eNumber 2 Morse taper (2MT) shank for self-centering spindle engagement\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated polished finish suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eInterchangeable pilot accepts 1\/4 inch pilot shank diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with drill presses and milling machines fitted with a Number 2 Morse taper (2MT) spindle socket and compatible with 1\/4 inch interchangeable counterbore pilots.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists or skilled fabricators into a 2MT taper-socket spindle. Ensure the machine is fully powered down and the spindle is stationary before seating or removing the taper shank. Use a drift key and dead-blow mallet to seat the taper properly and to eject it safely. Apply an appropriate cutting fluid for the workpiece material to extend tool life and maintain finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5-3\/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\u003ePilot Shank Diameter Compatibility\u003c\/strong\u003e: 1\/4 inch\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\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: GH8780488\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689071149362,"sku":"GH8780488","price":116.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d09cecd15b040b158a3bb79e34cc5abc.jpg?v=1788254445","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8780488-counterbore-3-4-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
