• The Fast Cut is ideally suited to cutting stainless steel and mild steel sheet, as well as tubes with a wall thickness of up to 1/8” (3mm). The maximum cutting depth is 1-5/8” (41mm). • The Deep Cut is ideal for cutting metal more than 1/8” (3mm) thick, tubes with a wall thickness of greater than 1/8” (3mm) and wood up to 2" (51mm) thick.
• The Fast Cut provides faster, smoother cutting on a wide range of materials. • The Deep Cut 2” cutting depth improves cutting performance on tubes, particularly where there is a need to cut through both sides of the tube.
