Built from high speed steel with a bright, uncoated finish, this tool delivers reliable cutting performance on ferrous and non-ferrous materials. The 1MT Morse taper shank provides a secure, self-locking connection in compatible drill press and milling machine spindles. With a 0.5 inch counterbore diameter and a 4.3125 inch overall length, this tool is suited for production and maintenance shop environments where consistent, repeatable results are required.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is intended for use in machine shops, maintenance facilities, and production environments where counterbored holes are required for socket head cap screws and similar fasteners. The interchangeable pilot design accepts a 3\/16 inch pilot shank, allowing the operator to swap pilots as needed without replacing the body. Right-hand cutting geometry is standard for use with conventional spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5 inch counterbore diameter sized for common socket head fastener applications\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry for balanced cutting and improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e1MT Morse taper shank for self-locking fit in compatible spindles\u003c\/li\u003e\n  \u003cli\u003eInterchangeable pilot accepts 3\/16 inch pilot shank diameter\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for easy visual inspection of cutting edge condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, milling machines, and similar machine tool spindles equipped with a Number 1 Morse taper (1MT) socket.
