Frequently Asked Questions

DIJ Ø 250 mm jaws — what does DIJ mean and for what type of clamping?

DIJ (Direct Inner Jaw) indicates jaws for internal gripping: the teeth bite from inside a hole or cavity, expanding outwards. Used for clamping hollow workpieces (rings, flanges, hollow shafts) by blocking them from inside the hole. The tooth geometry is optimized for internal gripping — they are not used for traditional external gripping. The Ø 250 mm size indicates the diameter of the compatible chuck, not the diameter of the bore that can be clamped.

DK12 series — compatibility with my chuck?

DK12 mounting (12 DIN 6350 bolts). Check the mounting type of your chuck before purchase — DK11 and DK12 are not interchangeable. The Ø 250 mm diameter 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 clampable range depends on the jaw travel in the chuck and the tooth geometry. As a reference for a Ø 250 mm chuck: the minimum clampable bore is approximately 15–20% of the chuck diameter; the maximum is approximately 60–70%. For applications outside this range, please contact Krollit. Customer support available in Italian.
