The DSH 700 hand-held gas saw performs well on a variety of construction materials, including wet/dry concrete, brick, and concrete block for small floor or wall openings. It also cuts rebar, bolts, dowel bars, grating and other metals. Isolated handles with metal springs minimize vibrations and maximize saw control. It also comes with a cyclone filtration system (no pre-filter) and simple rope replacement for easy maintenance and maximum durability. Hilti.
