Given the inflated cost of manufacturing these days, machine operators and manufacturers are constantly on the lookout for a more cost-effective ways to cut steel. Fortunately, the sawing technology has greatly improved. Technology has ushered in a new breed of saw blades that are specifically designed to cut down the manufacturing costs. 
Specialty Saws is the leader in providing premium products and has established an impeccable reputation as Melbourne’s leading distributor of Arntz products.


Blade Basics


Choosing the ideal blade for the material to be cut is critically important in ensuring cost-effectiveness of blade sawing. Here is some basic information to help you with your decision-making process: 
Blade Back. This refers to the body of the blade, excluding the tooth portion.
Width. The nominal dimension of a saw blade as measured from the tip of the tooth.

Thickness. The dimension from side to side on the blade.
Kerf. Amount of material removed by the cut of the blade.

TPI. The number of teeth per inch as measured from gullet to gullet.

Set. The bending of teeth to left or right to allow clearance of the back of the blade through the cut.

Tooth Pitch. The distance from the tip of one tooth to the tip of the next tooth.

Tooth Face. The surface of the tooth on which the chip is formed.

Tooth Rake Angle. The angle of the tooth face measured with respect to a line perpendicular to the cutting direction of the saw.

Gullet: The curved area at the base of the tooth. The tooth tip to the bottom of the gullet is the gullet depth.

Blade Construction

Bandsaw blades can be made from a single piece of steel, or built of two pieces. Your choice will largely depend on the life expectancy and performance requirements. Below are the key information you need to know about blade construction.

Bi-Metal 

This saw blade is composed of a high steel edge material. An electron beam is wielded to fatigue resistant spring steel backing. This specific construction is ideal for high performance cutting requirements and longer fatigue life.

Carbon

Hard Back. A one-piece blade made of carbon steel with a hardened back and tooth edge.

Flex Back. A one-piece blade made of carbon steel with a hardened tooth edge and soft back.
