Sandvik Coromant 5729331 Boring Head 63mm 69-87mm Bore

Product Description

The SANDVIK COROMANT 5729331 is a precision boring head designed for fine-boring operations in metalworking and machining environments. 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.

This 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.

Key Features

Compatibility

Designed 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. Confirm spindle interface and arbor compatibility with your specific machine before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with boring bar systems. Always power down and lock out the machine spindle before mounting or adjusting the boring head. Verify that the arbor and spindle interface are clean and free of debris before seating the tool. Follow the machine manufacturer torque guidelines for drawbar and clamping hardware - do not exceed rated values for the specific spindle type in use.
