Frequently Asked Questions

DIJ jaws Ø 315 mm — what does DIJ mean and for what type of clamping?

DIJ (Direct Inner Jaw) indicates jaws for internal clamping: the teeth grip from inside a hole or cavity, expanding outwards. Used to clamp holed parts (rings, flanges, hollow shafts) by blocking them from inside the hole. The geometry of the teeth is optimized for internal gripping — they are not used for traditional external gripping. The size Ø 315 mm indicates the diameter of the compatible chuck, not the diameter of the clampled hole.

DK12 series — compatibility with my chuck?

DK12 mounting (12 bolts DIN 6350). Check the mounting type of your chuck before purchase — DK11 and DK12 are not interchangeable. The diameter Ø 315 mm must match the chuck size. Customer support available in Italian.

What is the range of internal diameters that can be clamped with these jaws?

The clamping range depends on the jaw travel in the chuck and the geometry of the teeth. As a reference for a Ø 315 mm chuck: the minimum clampled hole is about 15–20% of the chuck diameter; the maximum is about 60–70%. For applications outside this range, contact Krollit.
