Bi-metal Hole Saws
HSS hole saws are used to saw through holes into various materials. The basic body is made of tool steel and has a HSS annular gear welded onto it. The crosswise put arrangement of the HSS saw teeth masters eff ortless the usage in steel and sheet irons, non-ferrous and light metals, wood, plasterboard, plastic, acrylic glass and many more.
The hole saws equipped with a HSS cobalt annular gear can also be used with stainless steels such as V2A and V4A sheets. The total height of the hole saws varies between 55mm and 43.5mm, depending on the size. GSR hole saws have a so called Vario-toothing.
