The Lenox Tri-Master versatile carbide-tipped band saw blade has a special tooth design with triple-chip grind and a positive rake angle for smooth, fine-finish cuts on wood, mold steel, carbon steel, tool steel, alloy steel, bearing steel, stainless steel, titanium alloys, nickel-based alloys, and aluminum and other nonferrous metals. The Tri-Master tooth design with triple-chip grind offers smooth cuts and a fine finish. The teeth are carbide tipped, which makes them harder and more wear resistant than bimetal or carbon steel. The blade has a steel backing for fatigue resistance. It can make cuts in solid shapes. The blade is available with a choice of variable pitch or constant pitch. The variable pitch has a variable tooth size and gullet depth to reduce noise levels and vibrations, and to remove chips efficiently. The constant pitch has uniform tooth spacing and gullet size for general-purpose cutting.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 tooth rake, tooth set, pitch, and size of the blade. Band saw blades are available with a positive rake angle or a straight (also called zero) 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 widths to fit the requirements of specific band saws. Lenox manufactures hand tools, band saw blades, and power tool accessories. The company, founded in 1915, is headquartered in Atlanta, GA.
