Abstract
A split ring alignment ring for holding a punch has a split ring by which the alignment ring can be tightened onto the punch shaft. The alignment ring has a pair of radially aligned cut outs, on its inner circumference and are on its out circumference. A pin on the tool shaft engages the inner cut out to fix the tool against rotational movement relative to the ring. A second pin projects axially from the top of a punch point of the tool to engage the outer cut out, also to prevent rotational movement relative to the ring.
