The Proxxon STS 12/E Jigsaw is ideal for making curved cuts in wood (up to 10mm), corrugated boards (up to 3mm), and non-ferrous metals (up to 2.5mm). It is equipped with a powerful 12-18 Volt 5-pole motor, offering a stroke of 6mm and variable speed control from 2,000 to 5,000 strokes per minute. The housing is made from stable, fibreglass-reinforced polyamide. This jigsaw includes two saw blades (one coarse and one fine). For optimal performance, a MICROMOT mains adaptor of at least 2.0A is recommended. Note that the speed control functions best with non-stabilised power supply units. The device operates at maximum speeds when connected to stabilised power supply units or batteries.
