Frequently Asked Questions

PO3 chuck Ø 315 mm — for which type of lathe and with which connection?

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

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 quick changes, the steel version is the correct choice.

The included jaw set — what size pieces can this Ø 315 mm chuck clamp?

The Ø 315 mm chuck includes rotating jaws (for external gripping) and drilling jaws (for internal gripping). As a reference: rotating jaws clamp pieces from approximately 5% to 60% of the chuck diameter. For very small pieces compared to the chuck, consider clamping pliers; for very large pieces, consider a larger diameter chuck. Customer support in Italian available.
