Big Kaiser’s 4-mm mini indexable boring bar is especially useful for small component machining. According to the company, the mini boring bar meets the demand for boring small parts in industries such as medical and aerospace for machined medical implant devices and micro-sized components.

This product only requires replacing the indexable insert versus replacing the entire bar where the cutting edge is integral to the bar. Also, the inserts can be exchanged without disturbing the geometry of the tool. Indexable inserts feature sharp cutting edges that help lower cutting forces and vibration, and inserts with specially developed cutting geometry for carbon steel, alloy steel and aluminum are available.
