A basis tool for machinists and toolmakers, the Universal Surface Gauge is used for accurately scribing lines, transferring measurements or probing surfaces in inspection work.
DescriptionDesign incorporates:
1. A fully hardened and ground base which serves as an accurate reference surface.
2. A machined Vee groove in the base allows the gauge to be used conveniently on curved surfaces.
3. A Vee groove at the front end allows the spindle to adjust to any angle above or below the base allowing it to be used as a height gauge and also as a depth gauge.
4. Two retractable pins allow the gauge to be located against the edge of a surface plate or T-slot for linear work.
5. Grooves on the side of the base allow for comfortable grip.
6. Well tapered scriber for better sighting while working. The scriber tip is hardened to 55-60 HRC.
