The Akku-Compact Flex® Punch Driver is a handheld battery-powered electro-hydraulic device for making holes of different shapes in soft to medium-strength steel, stainless steel and aluminium sheets. ALFRA punch drivers require little maintenance thanks to the closed hydraulic circuit and enable you to work in any position.
The flexible hand strap (K), which is attached to the drive unit (F), ensures perfect handling of the punch driver. A long hydraulic hose (C) makes punching even in difficult situations easy and comfortable. The integrated hydraulic pump is equipped with a microprocessor and generates the working pressure. The pump can be activated by pressing the Start/Stop button (D) and the necessary working pressure is built up, which pulls the load piston (A) inwards into the cylinder (B) with great force. The pressure is released by
pressing the return button (E).
The LED (G) on the device base show the operating status of the punch driver. The high-performance lithium-ion battery (H) can be removed by pressing the release button (I) and is equipped with a charge level display (J). Electronic and mechanic excess pressure valves limit the maximum attainable pressure within the device and thus protect the hydraulic punch from excessive use and damage.
Perfect punching results will be achieved using the suitable ALFRA tools. An overview of our range of quality round and square punches can be found at the end of this operating manual.
