Frequently asked questions

DOJ Ø 100 mm jaws — what does DOJ mean and how do they differ from DIJ jaws?

DOJ (Direct Outer Jaw) indicates external gripping jaws: the teeth bite from the outside diameter of the workpiece, clamping inwards. These are the standard jaws for clamping bars, shafts, cylinders, and compactly shaped workpieces. DIJ jaws do the opposite — internal gripping on hollow workpieces. The same machine can use both DIJ and DOJ depending on the workpiece, provided the chuck size is compatible.

DK11 series — compatibility with my chuck?

DK11 mount (11 DIN 6350 bolts). Check your chuck's mount type before purchasing — DK11 and DK12 are not interchangeable. The Ø 100 mm diameter must match the chuck size. Customer support in Italian available.

Hard DOJ jaws vs soft jaws — when to choose one over the other?

Hard DOJ jaws (hardened) are for general use on steel, cast iron, and raw aluminum — they grip firmly without deforming but leave marks on finished parts. Soft jaws (mild steel) do not leave marks on already machined parts and are machined in situ for maximum concentricity. For finishing operations on already machined parts: soft jaws. For roughing and production on raw parts: hard jaws.
