Frequently Asked Questions
DIJ Ø 630 mm jaws — what does DIJ mean and for what type of clamping?
DIJ (Direct Inner Jaw) indicates internal gripping jaws: the teeth grip from inside a hole or cavity, expanding outwards. Used to clamp hollow parts (rings, flanges, hollow shafts) by locking them from inside the bore. The tooth geometry is optimized for internal gripping — 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.
DK11 series — compatibility with my chuck?
DK11 attachment (11 DIN 6350 bolts). Please check the attachment type of your chuck before purchase — DK11 and DK12 are not interchangeable. The diameter Ø 630 mm must match the chuck size. Customer support in Italian available.
What is the range of internal diameters that can be clamped with these jaws?
The clamping range depends on the jaw stroke 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 about 60–70%. For applications outside this range, please contact Krollit. Customer support in Italian available.
