The Moto Saw has recommended thicknesses depending on what material is cut. For the most part for plywood, pine and poplar, it would be 3/4". For Balsa it's 1.75" and for laminate flooring, it would be .5". If cutting metal, for HVAC, Tin, AL sheet and Galvanized sheet metal, you can only cut up to 20 gauge. For Plexiglass it's .2" and PVC Pipe it's .75".
I hope that this has helped you out.
