Why Buy A Balanced Toolholder?

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.

Toolholders can greatly influence the difference in tool life.

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.

Why Are They Balanced To G2.5 or G6.3?

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.
