The 4 jaws adjust independently — each jaw moves separately to adapt to any shape. Centering takes more time (3–5 minutes with a dial indicator) compared to the self-centering PO3, but the achievable precision is higher: \u003c0.01 mm with a dial indicator. The PO3 is faster; the PO4 is more versatile.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eD5 DIN 55029 camlock mount — how does quick mounting work?\u003c\/summary\u003e\n\u003cp\u003eThe D5 camlock mount allows mounting and dismounting the chuck in less than 30 seconds: turn the locking flange a quarter of a turn. The cam guarantees repeatability of positioning \u003c0.01 mm with each mounting — the chuck always returns to the same angular position. Check the mount code (D5) of your lathe before purchasing.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre the included jaws reversible for external gripping?\u003c\/summary\u003e\n\u003cp\u003eThe included kit contains rotating jaws (external gripping) and boring jaws (internal gripping). For gripping sturdy parts from the inside, boring jaws are used; for standard external gripping, rotating jaws are used. The PO4 jaws are not reversible — they are replaced with the appropriate type based on the operation.
