Gagemaker’s internal diameter and groove gages measure variation in internal bore diameters. Setting dimensions for the pitch diameter gages are provided by the TDWIN Taper software. Gages require setting with a standard or on a MIC TRAC™. Gages are shipped with two 0.144″ diameter contact points (T144) as standard, but other points may be substituted. Software, standards (see below), and additional contact points are sold separately.
