The KSF-08/RC is a 210mm diameter chuck with a 66mm through hole, while the larger KSF-10/RC is 254mm diameter with an 82mm through bore. Both are rated up to 5000 rpm and can be specified with A2-5, A2-6 or A2-8 spindle mounting plates. 

Featuring a boltless design the rapid change jaws offer a full jaw area for clamping. Supplied soft as standard, with hard jaws available as an option, they can be exchanged in seconds but remain precise. The KSF chucks have a repeating accuracy of 0.0025 mm, such that when top jaws are finished machined on the chuck, MicroCentric guarantees that parts will run within 2.5 micron radial and lateral TIR if the top jaws are not removed from the chuck. After machined top jaws are removed and then replaced onto the same base jaw as they were machined on, a maximum runout of 0.025mm TIR is guaranteed.
