Item: 3219

** This product is no longer available **

This is an abutment rod for an SIP (Societe Genevoise D'instruments De Physique) universal measuring machine, such as model 305M. Taps with an odd number of flutes cannot be measured between two feelers, since one would not have contact. Their radius is measured using the moving feeler. The movement of the transverse center support is prevented by the anvil of the abutment rod.
