Blade Selection Guide
Helping YOU Choose the RIGHT Blade
TecSaw supplies many variations of WIKUS band saw blades for metal. Selecting the proper bandsaw blade is a lot like any other manufacturing decision. To start, you must have an understanding of the work that needs to be done, and then select the correct tool for the job.
Here are some useful steps to help determine what you need:
The band dimension depends on the band saw metal cutting machine for which it is required. This information is specified by the metal cutting machine type.
• Have a horizontal metal cutting machine? The horizontal metal bandsaw blades width is specified by the manufacturer.
• Have a vertical band saw? They allow higher variations of the band width.
• General rule: the wider the band saw blade, the higher its stability.
• Contour Cutting: the smallest radius to be cut is the limiting factor for the band width.
Cutting Edge Materials
The material to be cut determines the cutting edge material. Carbon steel blades; bi-metal blades; and coated and uncoated, carbide-tipped blades are widely used for the cutting of wood, steels and nonferrous metals. Carbide-grit and diamond-grit blades are used for more exotic applications like the cutting of abrasive building materials, fiberglass, and silicon.
TecSaw offers four main groups of WIKUS cutting edge materials:
• Carbon Steel
Hardness: approx. 850 HV
Tempering resistance: approx. 200°C
• Bi-Metal Steel
Hardness: approx. 1000 HV
Tempering resistance: approx. 600°C
Hardness: approx. 1600 HV
Tempering resistance: approx. 800°C
Hardness: approx. 9000 HV
The machinability of the material to be cut determines the cutting edge material.
Tooth Pitch (TPI)
Selecting the correct tooth pitch is crucial for good cutting performance and long blade life. Contact length determines the pitch. The contact length is either the width of the material on a horizontal bandsaw machine, or the height of the material on a vertical bandsaw machine.
Tooth pitch is measured in tooth per inch (TPI). A blade with a TPI of 3-4 has a minimum of 3 an a maximum of 4 teeth within an inch. The higher the number, the finer the tooth pitch.
The rule of thumb is to have no less than 3, but no more than 24 teeth in the workpiece. This gives some room to play, and the final selection of the TPI depends on cutting time and the desired surface finish. The more coarse the tooth pitch, the rougher the finish, but the faster the cut, and vice versa.
A selection of constant and variable tooth pitch are available.
|Constant Tooth |
|Contact Length (Inches)|
|Variable Tooth |
|Contact Length (mm)|
The material to be cut and the shape of the material dictate tooth form – the tooth angles (zero degrees, positive or negative cutting angle) and the tooth shape.
The combination of the various tooth shapes, cutting-edge materials and dimensions allow for your extreme performance cutting needs.
