These live centers are intended for quick and
simple clamping of work pieces with holes of large dimension,
which can not be clamped by normal type centers. The rotating
part of the live center is terminated with a 1:10 taper, to which
a tapered clamping insert with a point angle of 60°or 90°
is fitted as required.
