A bandsaw (also known as a band saw) is a machine, a stationary tool, a saw, with a long, sharp blade, that consists of a band that is continuous with toothed metal aligned in-between several wheels for cutting materials. Band saws are used in metalwork, woodwork, or for the lumbering purpose.

Band saws mainly consist of two wheels that rotate at the same plane; however, some of them may consist of three to four planes for load distribution. The blade comes in different sizes and shapes and tooth per pitch count (TPI), this makes the machine to be efficient in cutting a variety of metal sizes and shapes, different wood and plastics.

Initially, most band saws were powered by humans, they were called line shafts, but they have been replaced by the electric motors driven band saw. These motor-powered band saws are quick in cutting materials and more efficient, the human power is not too much needed when operating them, the only experience.

History of Band Saw

Bandsaw was first invented by William Newbery back in the year 1809; this idea became widely famous until the British government awarded him for such an awesome innovation. However, due to lack of advanced technology back then, band saw were not too much effect, they were not strong when cutting hard materials because the blades produced back then could break because they were not strong.

Until some years later, technological advancement led to the production of blades made from allows which were strong and could not break easily.

Basics of a Band Saw

Band saws are made in different sizes and shapes depending on the intensity of your work, big companies, for example, cannot go for small band saws designed to do small errands. The small benchtop band saw is usually used by middle or small companies. The bench top band saw operates on top of tables, and they are not heavy, they are small and portable.

The other model is the floor one, unlike the bench top, this one is heavy and cannot be placed on top of benches, but rather placed on the floor since they are designed to perform heavy tasks. The top bench band saw is operated by a few individuals, however on the contrary, due to the size and workload performed by floor models band saw, more people are needed to operate it.

Moreover, professionalism in most cases is required. Band saws produce finely cut edges due to evenly distributed teeth; the recent band saws can cut curved lines and shapes.

How The Band Saw Works

Step1: Setting Up the Machine

When working or preparing to use a band saw, you should always set it up properly; the bench ones should be placed on a stable bench to avoid shaking when using. Shaking of the band saw when been operated produces shapes of cuttings that are not desirable or smooth.

The blade should be attached firmly on the motors belt. Working should not start immediately, giving your machine some test is needed to establish how it is working. Once you confirm that the machine is okay, work can now start.

 Step2: Cutting a Straight Line

It is always necessary to establish the easiest work first when beginning to work. This will ensure desirable outcomes, for instance, when working on wood; cutting it in straight shapes will help you proceed to other complicated tasks effectively. People who cut curved shapes have been recorded saying that it is easier to begin with straight shapes then curve the desired shapes out of the straight ones.

When cutting wood, mark the areas that should be cut using some marker pen or a pencil. Accurate measurements are needed whenever cutting the materials; inaccuracy may lead to wastage of the resources, this is due to repeated cutting and discarding of wrongly cut ones, all this process of cutting uses power too.

Step3:  Cutting the Curved Edges

After cutting straight edges, now you can proceed to shape and design curved edges if they are your desired products. Cutting curved shapes and edges should be started by marking the curvatures carefully to be cut. This process is accomplished if you consider marking relief cuts first.

Relief cuts are the parts where you will pass the blade first; they lead the way to the desired curvatures when relief cuts are not done effectively, the whole process is spoilt, and a new procedure is required. Therefore, care should be given when designing and cutting relief cuts. The process of curving using a band saw is gradual, and the cutter should do it bit by bit and pause at the relief cuts once in a while.

Step4: Maintenance

Every tool must be maintained to improve work efficiency, reduce power usage, to increase durability and reduce the risks of injuries when operating the machine. Checking the motor regularly help in maintaining the durability of the belt. The belt is checked whether it is loose, when loose or worn out, it is necessary to change. Frequent cleaning of the motor is essential for increasing work efficiency.

Blades lose sharpness now and then; it is necessary to sharpen it regularly to produce smooth cuts and curves. Overheating of the blade is reduced by using cool blocks; these blocks ensure the durability of the machine too. The lubrication fluid in the machine should be replaced after every four months

How Does A Band Saw Work?

The operator of a band saw positions the wood or any material they are cutting under the blade and start the motor. The band saw blade is lowered to the material to be cut.  The cutting process begins when the blade of the band moves.


A band saw is an important tool in most woodwork, plumbing, and metalwork, it is necessary to understand how to operate it and maintain. Some band saw comes with an operation manual that will help you with maintenance. Therefore, it is necessary to learn the limitations of the use of the band saw before starting working with it.
