with 2 exchangeable spreading inserts (5 and 8 mm depth) and 8,10, 12 mm guide pins
e.g. for the shock absorber reception in the wheel bearing housing when changing the damper, for wishbone ball joint reception when disassembling the suspension strut
slipping off is avoided by strong guiding bolts that are stuck in the screw holes
a spindle with 13 mm outer hex pushes the spreader in the opening, no need to use a hammer
material fatigue and breakage esp. of aluminium parts is avoided
