Built from high-speed steel with a bright, uncoated polished finish, this tool delivers consistent cutting performance across a range of ferrous and non-ferrous materials. The 1MT Morse taper shank provides secure, repeatable tool holding in compatible drill presses and milling machines. With 3 right-hand cutting flutes and an overall length of 3.8125 inches, the GH8780181 is suited for shop operations where accurate counterbore depth and concentricity are required.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is intended for use in machine shop, maintenance, and fabrication environments where interchangeable pilot systems are already in place. The 1MT Morse taper shank is compatible with drill presses, knee mills, and machining centers equipped with a No. 1 Morse taper socket. A pilot shank diameter of 3\/32 inch guides the tool accurately into pre-drilled holes. It is typically installed and operated by machinists, tool-and-die technicians, and maintenance mechanics performing bolt seat and fastener clearance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/32 inch counterbore diameter for precise fastener seat preparation\u003c\/li\u003e\n  \u003cli\u003e3 right-hand cutting flutes for smooth material removal\u003c\/li\u003e\n  \u003cli\u003eNo. 1 Morse taper (1MT) shank for secure machine tool holding\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated polished finish — no additional coating to affect dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eInterchangeable pilot design accepts 3\/32 inch pilot shanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with interchangeable pilot counterbore systems accepting a 3\/32 inch pilot shank diameter.
