Rego-Fix's powRgrip PG 32 system uses a toolholder and collet to generate a high clamping force while still maintaining a TIR of less than 0.0001". The toolholder gives customers the ability to clamp tool shanks ranging to as much as 1" in diameter, an increase from the previous maximum clamping capacity of 0.75". Additionally, the toolholding system is especially useful for high-speed machining applications and offers an extensive taper selection, including CAT, BT, HSK and TC versions. The PG 32 is balanced by design, improving part quality and surface finish and lowering manufacturing costs, the company says.

The collet is inserted into the holder using a table-top mini-press that generates 9 tons of force. Available in both metric and inch diameters of as much as 1 inch (25 mm), the system relies on the interference between the holder and collet to create its clamping force.

Unlike other clamping systems where heat or hydraulics are used to expand the material, this toolholding system uses the mechanical properties of the holder material to generate tremendous gripping force with runout below 0.0001". Designed for easy operation and use, it takes less than 10 seconds to press in a tool or remove it from the holder. Because no heat is used, tools can be used immediately after a tool change.
