Our shrink fit chucks by ZOLLER are manufactured exclusively from high-temperature tool steel. When used properly, our shrink fit chucks can be used for more than 10,000 shrinking operations without losing accuracy.

All toolholders fine balanced to G2,5 25.000 or max. unbalance <= 1 gmm, for:
▪ smooth and bearing protecting spindle run
▪ longer spindle life cycle
▪ maximum tool life
▪ better milling surface

Low invest, high return
The cost of tool holders is less than 1 % of the total production costs of a
workpiece and therefore nearly insignificant. But they offer enormous savings
potential: because high quality in the tool holding interface enables you to:
▪ increase tool life significantly,
▪ improve machining processes in terms of productivity and workpiece quality,
▪ extend the life of the spindle.
As our calculation example shows, the use of high-quality ZOLLER tool holders lead to
significant savings in the tool costs. Even one tool holder can reduce the cost of the tools used in it by more than 6.000 €, with an additional investment of less than 50 €. Who invests in ZOLLER, benefits from a top return!
