Boasting unmatched accuracy at high speed and with minimum clamping force, Leader Chuck Systems can supply a wide range of high-accuracy chucks that operate at spindle speeds up to 8,000 revs/min and provide standard runouts within 0.002mm TIR. The chucks are available in diameters of 75 to 400mm.

The unique design of the MicroCentric HSV range, for example, counters the loss of jaw grip due to centrifugal force and offers constant chucking grip through the critical speed range of 2,000 to 5,000 revs/min, where most precision high-speed turning is carried out. But, more importantly, there is no increase in the original static grip when the spindle is stopped, as happens with conventional centrifugally counter-balanced chucks.

They can be supplied with the QC quick change jaw system, which is based on precision tapered locating buttons, to minimise set-up times while maintaining accuracy.
