Frequently asked questions
PO3 Ø 100 mm chuck — for which type of lathe and with which connection?
The PO3 chuck is a self-centering 3-jaw 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 bolt circle diameter of your chuck before purchasing.
The steel version PO3 vs the cast iron version — what's the concrete difference?
The steel version PO3 is 20–30% lighter than cast iron for the same diameter — it reduces start/brake times and vibrations at high speed. Steel allows higher maximum rotation 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 100 mm chuck clamp?
The Ø 100 mm chuck includes rotating jaws (for external gripping) and drilling jaws (for internal gripping). As a reference: 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.
