Frequently Asked Questions

DIJ Jaws Ø 630 mm — what does DIJ mean and for what type of clamping?

DIJ (Direct Inner Jaw) indicates internal gripping jaws: the teeth bite from inside a hole or cavity, expanding outwards. Used to clamp hollow workpieces (rings, flanges, hollow shafts) by gripping them from inside the bore. The tooth geometry is optimized for internal gripping — they are not used for traditional external gripping. The Ø 630 mm size indicates the compatible chuck diameter, not the diameter of the hole that can be clamped.

DK12 series — compatibility with my chuck?

DK12 mounting (12 bolts DIN 6350). Check your chuck's mounting type before purchasing — DK11 and DK12 are not interchangeable. The Ø 630 mm diameter must match the chuck size. Customer service 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 tooth geometry. As a reference for a Ø 630 mm chuck: the minimum bore that can be clamped is approximately 15-20% of the chuck diameter; the maximum is approximately 60-70%. For applications outside this range, contact Krollit. Customer service available in Italian.
