The Starrett Duratec PH carbon steel band saw blade has a hook tooth, raker set, and a positive rake angle for cuts on aluminum and other nonferrous metals. The blade can make cuts in solid, structural, and tubular shapes, as well as solid and tubular bundles. The hook tooth has a positive rake angle for fast, general-purpose cutting, with deep gullets, or spaces between the teeth, allowing the blade to cut softer materials without overloading the gullets with chips. It is made of a single piece of carbon steel with precisely hardened teeth and a spring-tempered back for increased cutting rates and accuracy. The blade has a raker set, which alternates between left-leaning, right-leaning, and unset teeth, for increased chip evacuation that reduces clogging.
Band saw blades are long, continuous bands of metal that loop around the wheels of band saws and can make straight or curved cuts in metal, wood, stone, plastic, and other materials. When purchasing band saw blades, consider the application, as this will affect the choice of tooth rake, tooth set, pitch, and size of the blade. Band saw blades are available with a positive rake angle or a neutral (also called zero or straight) rake angle, and with a raker, wavy, or alternate tooth set. Pitch (the number of teeth per inch or per 25.4 mm) affects the type of finish and may be constant or variable. Band saw blades are available in different lengths and width to fit the requirements of specific band saws.
