The hydraulic gage instantly reads in ft/lbs the amount of pull force being applied to the toolholder.  Once drawbar force drops below 80% of the original manufacturer's setting, it is time to schedule maintenance.

The innovative engineering design of two main parts is said to make it the first universal gage on the market−allowing it to be used anywhere in the shop to check all types of V-flange spindles. These key advancements have also allowed JMPP to reduce the price of the product by approximately one-half based on the size of the gage head and taper(s). For long-term value, the Clamp Force Gage can be cost-efficiently recalibrated by JMPP.
