Saws expanded polystyrene

 

— saws designed for sawing polystyrene foam and other similar types of foam plastic (foamed plastic). Usually, they are standard in shape (see "Type"), while the teeth are made small (about 18 – 19 TPI), and the cutting edge has a wavy shape, which allows the blade not to get stuck in the material, ensures accuracy of the cut and reduces amount of waste. One of the most popular options for using such tools is the preparation of material for external insulation.
