With a body diameter of 63 mm and a bore diameter range of 69 mm to 87 mm, this head provides adjustable, accurate bore sizing across a practical working range. It is used with compatible boring bar systems and CNC or manual milling machines where tight bore tolerances are required. Installation and setup are performed by machinists and tooling specialists in production or job-shop settings. The 5729331 weighs 4.31 pounds, making it a substantial precision component suited for stable, repeatable cuts.\u003c\/p\u003e\n\u003cp\u003eThis boring head fits applications in general machining, mold and die work, and precision component manufacturing where bore diameter must be dialed in with accuracy. It is suited for horizontal and vertical machining centers as well as manual boring mills. The adjustable bore range of 69 mm to 87 mm covers a wide variety of workpiece requirements without requiring a tool change, reducing setup time on complex jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBody diameter of 63 mm for compatibility with standard boring bar interfaces\u003c\/li\u003e\n  \u003cli\u003eAdjustable bore range from 69 mm to 87 mm in a single tool\u003c\/li\u003e\n  \u003cli\u003ePrecision construction supports tight bore tolerances in production environments\u003c\/li\u003e\n  \u003cli\u003eWeighs 4.31 pounds  -  substantial build for vibration-damped, stable cuts\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging for direct toolroom or machine deployment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style boring head replacement or addition for machining setups requiring a 63 mm body diameter tool with a 69 mm to 87 mm bore diameter range.
