Micro boring bars are specialized tools designed for precision boring operations in small-diameter holes. Designed for achieving extremely accurate hole sizes and finishes, which is crucial in high-precision applications. They have high accuracy and repeatability, which makes them useful for machining close tolerances.

Facilitates precision adjustment with least count of 1 micron radially. Used for finish boring applications with a range of diameters from 40mm to 350mm.

Pre-loaded assembly of MBU guaranteeing almost zero backlash. Adjustment can be done directly while the tool is on the machine, thus reducing downtime or setting time.

Our micro boring bars are manufactured based on our customers’ requirements. They can be used with a wide range of inserts, providing greater flexibility.
