In addition to reinforcing concrete and masonry, steel bars and rods also work to shape structures, which is why tools for bending, angling, and cutting through thick steel are important, enabling precise manipulation of hard steel. Specialised tools make these processes easier and more efficient, while keeping workers safe from injuries. The use of inappropriate or merely adapted tools like cutting torches and other cutting tools can be hazardous and put users at risk of workplace accidents.http://www.steelbarmachine.com/rebar-cutter/
