The standard DIN 6350 flanged attachment requires tightening the fixing screws for mounting. Check the number of holes and the diameter of the bolt circle of your chuck before purchasing.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003ePO3 steel version vs cast iron version — what is the concrete difference?\u003c\/summary\u003e\n\u003cp\u003eThe steel version of the PO3 is 20–30% lighter than cast iron for the same diameter — it reduces start\/brake times and vibrations at high speeds. 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eThe included jaw kit — what size pieces can this Ø 250 mm chuck clamp?\u003c\/summary\u003e\n\u003cp\u003eThe Ø 250 mm chuck includes rotating jaws (for external clamping) and drilling jaws (for internal clamping). 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.
