The band saw is a power tool that is used for cutting materials such as the log, sheet metal and the meat. There are different typed of band saw that are used for different purposes, i.e. for meat cutting band saw used is different from the band saw which is used to cut the log. There are various types of band saws namely bench top band saw, circular band saw, automated band saw etc, each of the type of band saw is specially design to accomplish a particular type of cutting. The porta band saw is another name for portable band saw, which is used to cut metal, thus it is a portable power tool and uses the dc battery energy which is converted into mechanical drive of the band saw.

Porta band saw has special characteristics which make the porta band saw the hottest selling band saw in the tool industry; the special characteristics include the multitasking capabilities of the portable band saw. Heavy duty porta band saw can take multitude of concrete and metal of various sizes and shapes with the finest accuracy in cutting even the hardest of materials. They are built with most distinguishing factors such as the ball and roller bears, the chain drive, worm based gear system and non oil based lubrication. These factors ensure accurate and fast cutting of materials without slipping from the desired line of movement.

The cutting capacity of the 6.6 ampere portable band saw is as powerful as 5 inch x5 inch, this is achieved by the chain drive and worm based gear mechanism of the porta band saw. The chain mechanism in the portable band saw also enables the band saw to operate at various speed levels, these speed levels can be adjusted in order to minimise the tooth imprint on the material which is been slotted of by the portable band saw. The worm gear mechanism of the band saw incorporates a firm grip of the band saw over the cutting material, thus minimising the chances of errors in cutting due to slipping of band saw.

Porta band saws are generally best suited for cutting metals such as the angle iron channel etc, the advantage that portable band saw has over other power tools widely used in the industry is that the portable band saw does not require any pre-cutting measure that has to be performed before cutting, the bans saw works without any prior setup. They can be moved from on site to another easily and also can be used any anywhere as they are battery operated and light weight.

One of the most important advantages of porta band saw over others is with the ease in changing blades. Portable band saw is a bladed tool, like any other bladed tool the efficiency of cutting by the band saw depends on the course of the blades, while cutting a thin material a fine blade is used whereas while cutting a thick material a sharp blade is used.
