They are standard jaws for clamping bars, shafts, cylinders, and compact-shaped workpieces. DIJ jaws do the opposite — internal gripping on hollow workpieces. The same machine can use both DIJ and DOJ depending on the workpiece, provided the chuck size is compatible.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDK11 series — compatibility with my chuck?\u003c\/summary\u003e\n\u003cp\u003eDK11 mount (11 DIN 6350 bolts). Verify your chuck's mount type before purchase — DK11 and DK12 are not interchangeable. The Ø 160 mm diameter must match the chuck size.

Soft jaws (mild steel) do not leave marks on already machined workpieces and can be machined in situ for maximum concentricity. For finishing operations on already machined parts: soft jaws. For roughing and production on raw parts: hard jaws.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working days shipping.
