Big Kaiser offers its Smart Damper boring bar for lathe applications. A heavyweight, strengthened damping mechanism integrated into the toolholder functions as both a dynamic counter and friction damper. It instantaneously absorbs vibration and eliminates chatter, promoting higher machining accuracy, better surface finishes and increased metal removal rates for higher productivity at critical machining depths, the company says. It supplies coolant through the body directly to the cutting edge.

The boring bar features three modular insert holders optimized for right-hand ID turning with ISO-standard inserts at a minimum diameter of 1.58". Metric bodies are available in 32 and 40 mm in diameter, with inch versions at 1.250 and 1.500". This system is said to enable boring depths of approximately 7×D.
