Essential Tips For Choosing Bandsaw Blade

“New technological changes are making sawing a potential source of efficiency.”

The last giant leap in band saw blade technology happened in the mid 1960s with the establishment

of bi-metal technology, which was soon followed by the introduction of carbide-tipped blades. Band

sawing efficiency was limited prior to the advent of bi-metal blades. The band saw blade used to be

made entirely of high carbon steel because it was pliable enough to withstand the stress caused by

its winding path around the band saw machine’s drive wheels and through the saw blade guides. As

it was necessary to use a softer, more flexible backing material, manufacturers were prevented from

capitalizing on the sawing efficiency that could be gained by using a harder material that would

provide a more durable tooth edge.

A bandsaw is a power tool which uses a blade consisting of a continuous band of metal with teeth

along one edge to cut various workpieces. It is a useful tool for metalworking due to its versatility

and precision. Its usefulness, however, depends on the blade. If you choose the wrong blade, teeth

can dull prematurely, damage your material, or break.

It's not difficult to choose the right blade for your application; all you need to do is carefully

consider and understand tooth shape, blade width, and teeth per inch.

Scrutinize-Performance, Durability, Cost

Performance, durability, and cost are important factors to pick the perfect blade for various

application. It is very important to get cheapest cost per cut, while maintaining acceptable levels of

surface finish, and ensuring optimized productivity and profitability.

Proper Usage

Using the blade appropriately for each type of cutting is important for the prolonged operational life

of the blade.

Essential Tips For Choosing Bandsaw Blade

One blade cannot be used for every purpose. So we need to determine the durability and capability

of blade to withstand the forces while quickly providing a smooth cut.

Determine the material

To determine the band saw blade that best suits our requirements, we must examine the materials

being cut, as sometimes cutting these hard materials requires more shear break for the material to

form the chip, creating a considerable amount of heat at the face of the tooth.

Blade Characteristics

• Hardness and strength of the cutting tool must be maintained at elevated temperatures.

• Toughness is necessary to prevent chipping or fractures.

• Wear resistance attainment of acceptable tool life before it needs to be replaced.

Blade Properties

Use the widest blade that machine can accommodate, except when cutting contours.The positive

tooth rake angle increases the tilt of the tooth face and is best-suited for thick solids and heavy-wall

tubing.

Heed Tooth Type

Regular tooth are used for general metal cutting with a straight rake.

Hook tooth are good for cutting hard non ferrous alloys, non metallics, plastics, and wood.

Skip tooth are best-suited for soft, non ferrous metals, plastics, and wood.

Blade Pitch

Pitch is the distance between one tooth tip and the next. For cutting thin sections of material fine

pitch is required and for coarse section thick pitch is required. A variable-pitch blade has various

tooth sizes and gullet depths to reduce noise and vibration when cutting structurals, tubing, and

solids.

Tooth Stripping

One of the most common problems in band sawing is stripping the teeth from the blade. Usually

this is due to overload of forces on the blade caused by repeated impacts with the material,

especially while cutting structural shapes and bundles.

While concentrating on above factors is not enough , brand name also plays an important role. As

getting a blade from BIPICO , India Knives Tools and Co. and other high profile manufacturing

companies provides a promising operational life of blades , its durability and quality.
