Combines a hand flange tool and hole punch in one single tool with air/hydraulic support. Ideal for jointing non-hardened body panels and for panel repairs and partial replacement with seamless transition. Also punches holes of up to 5 mm for gas metal arc welding thanks to the pneumatic/hydraulic power boost. Facilitates efficient and fatigue-free work despite one-hand operation. Quicker and less energy-sapping than hand flange tools.
