Tool holders make the all-important connection between the cutting tool and the spindle. With the hard-earned
money you invest in cutting tools, it only makes sense to do everything possible to increase tool life. One of the
easiest ways to do this is to use balanced toolholders.
The use of a balanced toolholder can result in increased accuracy and repeatability due to less vibration and
chatter. They can help to improve spindle bearing life and improve surface finish. They can save your time by
allowing for faster speed and feed rates. All of these benefits mean that you save time and money.
Quite simply, this means that the toolholder balance is consistent with the spindle as recommended by
International Standards Organization (ISO) standards. Balancing to the spindle is the best of class
balanced tool holder. KILOWOOD is international Quality AT3 Class balanced V-flange toolholder
manufactured to the highest degree of technical excellence.
