Band saw is a necessary tool for sawing wood materials and metal. It is used both in industrial production and for individual needs.
Almost all woodworking enterprises have such a tool. Band saw is an integral part of such machines as tape dividing and sawmills. The working blade is subjected to a special double hardening during its production. Each band saw has sharpened and divorced teeth. Such a cutting blade is capable of sawing even frozen and hard wood.
The band saw is available in several types (wide, narrow, wood, metal). Often, specialists working in the woodworking industry re-grind them for use on special machines. This procedure significantly increases the working resource of a wide cutting surface. A narrow web cannot be subjected to such a procedure, therefore it is used until it is completely worn out. Precise wiring of the saw teeth gives a guarantee of high productivity and excellent cut quality. The band saw has an increased resistance to overheating, since the additional heat treatment allows it to produce a straight cut. The cutting blade has a convenient sequence of straight, right and left teeth, which combine well with sharpening equipment.

, which allows for high-precision inclined and longitudinal cuts. They are often used for cutting stainless steel. Most often, a jigsaw is used at home. It is versatile and easy to use. Easily replacing its working blade, it is possible to saw through a laminate, wood, chipboard, polymers, ceramics and metal.
Since not only wood products, but also from more durable materials are used in various fields, the industry also produces band saws for metal. Step hardening gives them increased hardness. They are used to cut blanks from plastics, organic glass and metals.
Many companies produce mid-alloy steel saws. As an alloying element, tungsten, molybdenum, chromium or vanadium are used. Band saw for metal from this steel has a hardened edge of the working blade (0.6-0.8 cm tooth height). Such a sheet has a productivity several times greater than that of carbon steel. Molybdenum band saw is of three types: for high-speed, contour and straight cutting. Cutting blades are divided into 3 types: for magnesium and aluminum alloys, for cast iron blanks, for alloy steel.
Band saw is used on special machines designed for metalworking. Its use in this industry is the most promising type of resource-saving technologies. Continuity of cutting and narrow cuts determine the main advantages of this cutting method: low power consumption, minimum amount of waste (chips), obtaining accurate workpieces, versatility of the processing method.
