The saw off the catcher
A cold saw uses a circular saw blade to cut metal. The name "cold saw" comes from the cutting process using. These saws transfer the heat generated by the chip created by the cutting blade. Therefore, the blade and the material being cut remain cold, as opposed to a grinding saw, that abrades the metal and creates a large amount of heat in the cutting and metal blade. Cold saws use a solid high speed steel (HSS) or tungsten carbide tipped, circular saw blade resharpened. They are equipped with an electric motor and a reduction gear to reduce the speed of rotation of the blade, while maintaining constant torque. This allows the HSS saw blade to feed at a constant speed with a very high chip load per tooth. A cold saw cut produces minimal burr, sparks, no discoloration and no dust. The material to be cut must be mechanically clamped to prevent movement during the cutting process. Extra care should be taken to choose the appropriate number of teeth, saw blade, cutting speed and feed. All these variables are based on the type and size of the material being cut. Cold saws are capable of processing more ferrous and non ferrous alloys. Cold saws are intended to be used with a flood coolant system to keep the saw blade cool and lubricated.
