BIG KAISER introduces the 4mm mini indexable boring bar – suitable for small component machining. To date, BIG KAISER has one of the smallest indexable inserts in the market.

The mini indexable boring bar helps meet the increasing demand for successfully boring small parts in industries like medical and aerospace, such as machined medical implant devices and micro-sized components.

The main advantage of this product is the cost savings of replacing just the indexable insert in production versus replacing the entire bar where the cutting edge is integral to the bar. The inserts can be easily exchanged without disturbing the overall geometry of the tool, providing optimized cutting results.

Indexable inserts feature sharp cutting edges that help lower cutting forces and vibration and inserts with special developed cutting geometry for carbon steel, alloy steel and aluminum are available.
