Pneumatic metal shear

This tool uses the same action as snips,having twofixed blades and one blade moving vertically between them (Figure 3.46). This central movable blade cuts out a thin ribbon of metal which coils and is discarded. Cutting can be started from the edge of the panel,or from any point on the panel surface using a predrilled hole large enough to insert the central cutting blade. Radiuses up to in (200mm) can be cut on material up to 1.2mm (18 gauge). Care must be taken not to damage the panel surface by causing buckling during the cutting action.
