A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking , metalworking , and lumbering , but may cut a variety of materials.
If a bandsaw grabs, the wood is pressed safely down into the machine table (though the saw may jam, stall or break the blade). If a table saw grabs at the rear of the blade where the teeth are rising up from the table, it may rapidly lift the wood upwards.
As the logging industry expanded, the 1880s saw the introduction of mechanized equipment like railroads and steam-powered machinery, marking the beginning of the railroad logging era. Logs were moved more efficiently by railroads built into remote forest areas, often supported by additional methods like high-wheel loaders , tractors and log ...
In 1945, Rockwell Manufacturing Company acquired Delta Machinery and renamed it the Delta Power Tool Division of Rockwell Manufacturing Company and continued to manufacture in Milwaukee.

Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
The saw base can be adjusted for depth of cut and can tilt up to 45° and sometimes 50° in relation to the blade. Adjusting the depth of cut helps minimize kickback. Different diameter blades are matched to each saw and are available ranging from 14 to 61 centimetres (5.5–24.0 in).
