Hole Punch Machine Series H4
Technical Data

Hole Punch Machine Series H4 Air hydraulic punch tool for steel plate up to 3.5 mm

The H4 is an air hydraulic hole punching tool. The design allows the user to work using rapid strokes and considerable force. The hole is burr-free. The tool is both light weight and well-balanced to minimize the strain on the user. The air hydraulics also mean that the tool runs silently and is completely vibration-free.

The tool has few moving parts and has an extremely high level of operational reliability. And because we both design and manufacture the H4 Hole Punch ourselves, we can guarantee both a complete stock of spare parts and rapid service when  required.
