Gauge
The relief handle enables use without the encumbrance of handles for greater versatility of applications. May also be used with handles when desired.
Length varies with diameter from 1 7/8 in. to 3½ in. to provide more useable gauge surface. The concentricity of ends, plus extra length, is valuable for layout, hole spacing measurement. Each gauge is lapped to approximately one microinch finish that creates a mirror-like surface with additional resistance to wear.
Each gauge is heat-treated to a hardness of Rockwell "C" 62-64, and Cold Stabilized to minimum size and form variations throughout the exceptionally long life potential built into each Deltronic gauge.
