The 4 jaws are independently adjustable — each jaw moves separately to adapt to any shape. Centering takes longer (3–5 minutes with a dial indicator) than with 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\u003eStandard DIN 6350 connection — how is the chuck mounted?\u003c\/summary\u003e\n\u003cp\u003eThe DIN 6350 flange connection is mounted by tightening the fastening screws evenly in a cross pattern. It takes 5–10 minutes to mount. The angular position is fixed — the chuck should not be removed frequently with this connection.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eThe included jaws — can they be reversed for external gripping?\u003c\/summary\u003e\n\u003cp\u003eThe included kit contains scroll jaws (external grip) and boring jaws (internal grip). For gripping strong workpieces from the inside, boring jaws are used; for standard external gripping, scroll jaws are used. The PO4 jaws are not reversible — they are replaced with the appropriate type depending on the operation.
