Band saws are mostly used for industrial applications such as sawmills, cutting large stocks of lumber to size, especially where curved cuts are required. Versions made for home woodshop use are smaller but just as useful. These models will cut through wood thicknesses of up to 6 inches in either straight or curved cuts. Observe the proper safety guidelines, such as wearing safety goggles and suitable clothing.
A band saw blade consists of a toothed steel loop welded at the ends, moving on two encased wheels, which provide a continuous cutting edge. Home shop models have blades ranging from 1/8 inch to ¾ inch wide. Narrower blades are designed for cutting tight radius curves, while the wider blades are used for making more straight cuts. The teeth of the blades have a spacing of from 6 to 24 teeth per inch (called the pitch). Finer pitches are intended for cutting metals, and the larger pitches are good for cutting large sections of lumber.
