The inserts can be replaced separately when they wear out, without changing the base body. \"Reversible\" indicates that the same insert can be mounted in two opposite orientations — for internal or external gripping — without changing the jaw.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eFor Ø 250 mm — what is the clamping diameter range for these jaws?\u003c\/summary\u003e\n\u003cp\u003eReversible bolted-on jaws for a Ø 250 mm chuck clamp workpieces within a diameter range that depends on the jaw travel and the mounted configuration. As a general reference, the jaws cover a range of approximately ±30–40% of the nominal chuck diameter. For very small diameters (workpieces \u0026lt;Ø 20 mm on a Ø 250 mm chuck), consider smaller jaws or collets.

When the top inserts are worn or when you want to mount inserts made of a different material (e.g., soft inserts for delicate workpieces), you can unscrew the fasteners and replace only the inserts without having to buy the complete set of jaws. Replacement inserts are available separately.
