Frequently asked questions

PO3 chuck Ø 125 mm — for which type of lathe and with which attachment?

The PO3 chuck is a 3-jaw self-centering steel chuck with DIN 6350 centering. The standard DIN 6350 bolted flange attachment requires tightening the fixing screws for mounting. Please check the number of holes and the bolt circle diameter of your chuck before purchase.

The steel version PO3 vs the cast iron version — what is the concrete difference?

The steel version PO3 is 20–30% lighter than cast iron for the same diameter — it reduces start-up/braking times and vibrations at high speed. Steel allows higher maximum rotational speeds than cast iron. For high-speed lathes or for those who frequently work with fast changes, the steel version is the correct choice.

The included jaw kit — what size pieces can this Ø 125 mm chuck clamp?

The Ø 125 mm chuck includes rotating jaws (for external gripping) and drilling jaws (for internal gripping). As a reference: the rotating jaws clamp pieces from about 5% to 60% of the chuck diameter. For very small pieces compared to the chuck, consider clamping collets; for very large pieces, consider a larger diameter chuck. Customer support in Italian available.
