For workholding collets:
<a href="https://tacrockford.com/product/gauges/workholding/forcecheck-worholding-collet-force-gauge/">Series 495.245 ForceCheck Workholding Collet Force Gauge</a>

With the ForceCheck collet force gauge, the clamping forces on collets and hydraulic tool holders can be measured to obtain accurate machining specifications while fulfilling ISO standard requirements.

Available in complete sets for 1/4, 1/2, 3/4, 1, 10 mm, 16 mm, 20 mm, 25 mm and other diameters.

The ForceCheck collet force gauge allows tool holder and workholding collet holding force to be quickly and easily measured.

Because it is problematic to measure, this critical holding force is typically not checked, even though it plays an important role in manufacturing repeatability.

TAC Rockford, makers of the ForceCheck drawbar clamping measurement system, offers a simple, efficient, and consistently accurate collet force measurement unit.

With this system you can accurately and consistently measure the clamping forces on collets and hydraulic tool holders to obtain accurate machining specifications while fulfilling your company's or customer's ISO standard requirements.

Complete sets include a durable display with standard 9 volt battery, connecting cable, carrying case, and measuring bar.

Individual measuring bars for any size diameter are available.
