Used to clamp hollow workpieces (rings, flanges, hollow shafts) by locking them from inside the hole. The teeth geometry is optimized for internal gripping — they are not used for traditional external gripping. The Ø 80 mm size indicates the diameter of the compatible chuck, not the diameter of the hole to be clamped.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDK12 Series — compatibility with my chuck?\u003c\/summary\u003e\n\u003cp\u003eDK12 attachment (12 DIN 6350 bolts). Verify the type of attachment of your chuck before purchase — DK11 and DK12 are not interchangeable. The Ø 80 mm diameter must match the chuck size.

As a reference for an Ø 80 mm chuck: the minimum bore that can be clamped is about 15–20% of the chuck diameter; the maximum is about 60–70%. For applications outside this range, please contact Krollit.
