A band saw is a type is a type of a saw which has a long blade with a sharp metal tooth which is stretched between the more than two wheels for the purpose of cutting different materials. The band saw are used for the cutting of wood and metal as it cuts the material evenly and can also cut the curves like any other saw. The bands and the kerf of the bandsaw determine the curve of the material.
Now the band saw blades come in a variety of types and sizes with different tooth pitches which are able to cut different materials including wood, metal and plastic.
Before buying the band saws, you must know the certain features of the saws. You should check the depth and width of the cut through the band saw. Then you should also check its distance between the frame and the blade.
You also need to consider the motor size of the band saw. The normal amateur band saw model has around 1 horsepower motor whereas the professional band saw motors have more horsepower and speed than this.
There are different types of band saws blades which are useful in cutting different materials. It has a blade with the set of teeth at one side. The band moves in a circular direction through the two pulleys which hold the metal blade from one side. These are perfect for cutting the curves or irregular shape and are also good for cutting the straight shape.
The type of the blade depends upon the type of material you want to cut. There are five types of blades, which are:
l Hook tooth: it is used for the hard materials. The teeth are placed widely and its cut is around the angle of 10 degree. It has a very sharp and aggressive cut.
l Diamond tooth: it is used for very hard surface such as glass or concrete. It has the feature of grinding rather than cutting. The rectangular shaped teeth help in holding the diamond to make it tough.
l Regular Tooth: are ideal for the cutting the metal surfaces smoothly. They have fine teeth and are perfect for every material that needs to be cut.
l Variable tooth: these are perfect for contour type of work. They are called all-purpose blades as they are used for different materials to make different cuts and depths.
l Skip tooth: These are good for cutting soft materials. It has a cut of 90 degree angle. It is also called the all-purpose blades.
The new technology is also making the band saw a very a useful source in the industry. Two such technologies include the tooth geometry and the coatings. The manufacturers are still trying to bring improvements in these technologies but so far it has been very useful and helpful in the metal industries.
