Frequently Asked Questions

Reversible TJ top jaws Ø 250 mm — do they combine internal and external gripping in a single set?

Yes — this is the main feature of reversible TJ top jaws. The top inserts can be mounted in two opposite orientations on the same base body: "normal" orientation for internal gripping (clamping from inside the bore or recess), "reversed" orientation for external gripping (clamping around the external diameter of the workpiece). A single set replaces two separate sets of jaws — a concrete advantage for those who frequently work with both configurations.

How are the inserts reversed in practice — how long does it take?

To reverse: 1) loosen the insert fixing screws with the supplied wrench, 2) remove each insert, 3) reassemble it in the opposite position, 4) retighten the screws. This operation takes 2–3 minutes for a complete set of 3 or 4 jaws. The inserts have a notch or visual reference for correct orientation — it is practically impossible to mount them in the wrong position if the reference is followed.

The PS3 base body — compatible with which type of chuck?

The PS3 base body is compatible with 3-jaw chucks of PS type (front mounting with 3 screws). Please check the mounting type of your chuck before purchasing — the mounting is not interchangeable between PS3, PS4, and DK. Customer support in Italian available.
