iGaging 6" Dial Caliper
Tape measures and rulers might be fast and familiar, but
they don't provide enough information for making really precise machine setups
or accurately gauging the results of your work.
Every shop should have a means of measuring in thousandths
of an inch, and these budget priced calipers are a great place to start. The stainless steel construction is far more
rigid than plastic-bodied entry level calipers, and that stiffness results in
more consistent readings.
These 6"-range dial calipers accurately make
inside, outside, depth, and step measurements.
The analog dial is quicker to read than a digital readout when comparing
several project parts or boards, too.
