Variable spline indicator ring gauges are ideally suited to measuring component effective tool thickness. We can also supply spline indicators with two opposite sectors of teeth to measure actual tool thickness.

We can supply ring gages with analog or digital indicators—or even with transducer ports, making SPC type analysis possible on an external computer or other processing device.
