The powRgrip collet system by Rego-Fix uses a toolholder and collet that is designed to generate very high clamping forces equal to or higher than shrink-fit holders. The system includes a holder, collet and mini-press that generate 6 tons of force. The system relies on the interference between holder and collet to generate its clamping force. Unlike other clamping systems where heat or hydraulics are used to expand the material, the collet system uses the mechanical properties of the holder material to generate tremendous gripping force with runout below 0.0001”. Interchangeable collets are available from 1/8" to 1", including metric sizes and will hold both carbide and HSS tools.

The system is designed for easy operation and use. It takes less than 10 seconds to press in a tool or remove it from the holder, according to the company. Because no heat is used, tools can be used immediately after a tool change. Cycle testing exceeded more than 20,000 insertions and removals.
