Frequently Asked Questions

What is a DORIAN indexable boring bar used for?

A DORIAN indexable boring bar is used for precision internal boring operations in machining centers and lathes. It enlarges or finishes existing holes with replaceable cutting inserts, reducing tool change downtime. Common in automotive, aerospace, and general manufacturing for achieving tight tolerances on bores.

What are the specifications of the DORIAN S16T-MDUNR-3 boring bar?

The DORIAN S16T-MDUNR-3 indexable boring bar has a shank diameter of 16 mm and uses MDUNR-style inserts. Its manufacturer part number is 73310155066. This bar is designed for internal turning and boring applications where insert indexing provides consistent cutting geometry and extended tool life.

How to select the right DORIAN boring bar for a job?

Select a DORIAN boring bar based on bore diameter, depth, and material. The S16T-MDUNR-3 suits smaller bores with its 16 mm shank. Match insert geometry to workpiece hardness and finish requirements. For deep bores, consider bar overhang and vibration damping. Consult DORIAN's catalog or 3G Electric for application guidance.
