Why choose Press-Fit toolholding

The quality of the toolholding system has a direct impact on machining performance, tool life, surface quality and process stability.

The powRgrip press fit toolholding system is designed for high-speed milling, drilling, reaming and other demanding machining applications. Unlike heat-based tool clamping technologies, powRgrip clamps cutting tools mechanically without applying heat—making it a proven alternative to shrink fit tooling for shops that need both precision and throughput.

Key benefits of the powRgrip® Press-Fit toolholding system

Total system runout of ≤3 μm

The complete powRgrip system achieves a total system runout of ≤3 μm measured at 3 × D. High runout accuracy helps distribute cutting forces evenly and can contribute to improved tool life and machining quality.

Excellent vibration damping

The powRgrip press fit toolholding system provides excellent vibration damping, helping reduce chatter and support consistently high surface quality.

Tool ready in 8 seconds

With the PGU 9500 and PGU 9800 automatic clamping unit, tools can be clamped and are ready for use in approximately eight seconds.

High and consistent clamping force

powRgrip provides high clamping force and reliable torque transmission for demanding machining operations.

Repeatable performance

The system maintains high clamping force and low runout even after 20,000 tool changes.

No heat required

The press fit clamping process doesn't require heating or cooling of the toolholder. This enables simple and safe handling while ensuring a consistent workshop process.

Tailored to your application

The wide range of powRgrip® collets, available in various diameters and specialized designs, enables an application-specific clamping solution.

Test powRgrip® in your own production

Apply for an exclusive powRgrip Test & Trial

The most effective way to evaluate a press fit toolholding system is under real production conditions. With the powRgrip Test & Trial, you can test the system using your own machine, cutting tools, workpiece materials and machining parameters.

The test allows you to evaluate the performance of the powRgrip system under real production conditions. It provides valuable insights into tool life, surface quality, runout accuracy, process stability and vibration behaviour. In addition, setup and tool-change times, machining productivity and overall tooling costs can be assessed and compared with your current toolholding solution.
