Bandsaw blade selection


Amada logo
Use the bandsaw blade selector below to select the correct of tooth tip type and pitch when choosing a bandsaw blade for a particular material and saw.

Factors include:

  1. Material section (round, solid, flat, square, bundle)
  2. Material specification (grade, alloy etc)
  3. Treatment, hardness etc
  4. Maximum width of blade contact with material
  5. Saw machine design – rigidity, blade width

Select the band saw blade according to the material form and quality to be sawn taking account of the task. When sawing wide, rolled H profiles, the saw band can jam in the material to be sawn. In order to prevent this effect, a WS (wide set) is available for “PROTECTOR”. For solid material with larger diameters, we provide an Anti-Pinching variant (AP) of the “SUPER HL” to prevent jamming in the cut.

Choose a blade type
The basic requirement for cutting is that the tooth tip must be harder than the material to be cut. As a general rule of thumb, the tooth tips should be at least twice as hard as the material to be cut.

Choose the maximum width to be cut
Determine the section to be sawn (L). This is the maximum solid section that the saw blade has to cut through at any point.

Saw blade contact area selector

Using the maximum cutting width (L) determined from above, compare to the chart below to determine the ideal tooth pitch.

Bandsaw blade pitch selector

  1. For optimum sawing, we recommend selecting a toothing pitch which always has 10 to 20 teeth in the material.
  2. For sawing deformed workpieces or workpieces with varying cutting width, it is recommended during the cutting that at least two teeth penetrate the material simultaneously.
  3. The above table is based on a quality “SGLB” as guideline. Specific applications of other blades vary occasionally due to their characteristic properties. For example, a 3/4 teeth PROTECTOR can also cut material from the above 4/6 teeth/inch range.
Choose the ideal band speed and feed rate
Cutting rate means the machined area per minute and is expressed using the unit sqcm/min. To achieve the target cutting performance, calculate the cutting time according to the following equation and set the feed rate.

For simplified calculation of the surface area, use the following formula*:

  • Surface area of square material = width (cm) x height (cm)
  • Surface area of round material = Ø (cm) x Ø (cm) x 0.785

* For bundle cutting, multiply the number of the bundled bars by the value of the surface area of one bar.

Important preparations before cutting
  1. When you sharpen a pencil, don’t you always rub the tip lightly to round off the sharp brittle point to prevent it breaking off unexpectedly? A ragged broken lead spoils the line it draws and you soon have to sharpen it again. In order to achieve optimal blade life, saw blades must always be run in to gently wear the ultra sharp edges in a controlled manner. We recommend running in each saw blade until it has achieved approximately 3000 sqcm with the blade speed reduced to 70% and the feed rate reduced to 50%, after which the speed and feed can be increased to the optimum.
  2. There’s a reason EVERY sawing machine manufacturer fits a wire brush unit to their machines! Similarly, there’s a reason why EVERY blade manufacturer insists on the importance of having the brush unit in good working order, with a good quality brush and properly adjusted. Ensure that the swarf brush(es) of your machine is (are) always in good condition and engaged with the blade teeth. Replace worn brushes, otherwise the quality of the cut face and the blade life is reduced.
  3. Ensure sufficient concentration of the cooling lubricant; this should usually be approx. 10%. For stainless steels, a slightly increased concentration of approx. 12% has proven more effective. Only cast iron and plastic should be sawn dry. Old coolant is often partially broken down and ineffective as a lubricant, so change the coolant in your machines regularly.
