Hot Knives

A variety of blade options makes the hot knife hand held tools versatile. The hot knives are used in construction for cleanly cutting exterior insulation and finish systems (EIFS) boards, for cutting electrical box openings and utility access channels in insulated concrete forms (ICFs), and structural insulated panels (SIPs). The hot knives can also be used for cutting EPS foam for artwork, sculpting, packaging, and R&D applications.

The hot knife tools are made for cutting expanded polystyrene (EPS-white board) foam, Styrofoam™, Styropor™, and extruded polystyrene (XPS-blue and pink board) foam.
