There are literally hundreds of saws available in home improvement and hardware stores. Unless you are an expert, it can be rather difficult to differentiate between the many choices. While most of us are used to the idea of various types of saws being used to cut wood, there are also a number of choices of saws and blades specifically formulated to cut metal. For those with a greater level of expertise in metal working, cutting torches are also an option for cutting metal.
The handheld hacksaw is perhaps the most traditional and familiar of all metal cutting saws. Consisting of a rectangular frame with a thin, rigid blade on the bottom, a hacksaw easily cuts through metal pipe.
The cold saw is a circular saw that operates at low speeds, enabling the metal to stay cool. It uses high speed steel or tungsten carbide tipped circular blades.
Bi-metal saw blades can be purchased for hand held, electrical jig saws. These blades enable a jig saw to cut through metal.
Larger, and oriented more toward an experienced cutter, vertical and horizontal band saws may be used to cut metal, if an appropriate metal cutting blade and cutting fluid are used.
Oxy-fuel torches use oxygen to combine with heat generated by the flame and the metal. When the metal reaches high temperatures, it forms iron oxide and melts away from the cut site.
