Bandsaw Grades and Styles
|
|
Flexback
|
The most common and inexpensive material. The teeth are hardened but the edge opposite the teeth (the back) is not hardened. Hence "flexback". Good for Ferrous
Metals, Wood, Plastic, Aluminum and other non-ferrous metals.
|
|
Hardback
|
Same as flexback except the back is hardened. Useful in applications where there is heavy feed, particularly on horizontal metal-cutting machines. Good for
Ferrous Metals, Wood, Plastic, Aluminum and other non-ferrous metals
|
|
Bimetal
|
The edge where the teeth are created first has a strip of High Speed Steel electron beam welded to it. Then the teeth are milled or ground leaving the HSS only on
the points but not in the gullets where its hardness would cause the blade to break. Useful in high production or difficult to cut materials. Good for all materials -
particularly Stainless Steel.
|
|
Bimetal M42 or Cobalt
|
Same process as above except the HSS is of a grade that has more wear and heat resistance. Although it is often called "Cobalt" both grades have the same
percentage of cobalt but the element that actually makes the difference is unpronounceable. Best for Stainless Steel and other hard to cut materials.
|
|
Knife edge
|
Needs no explanation except that it is Used on paper, foam and similar materials.
|
|
Wavy Edge
|
The cutting edge has a sinusoidal like shape. Useful on foam.
|
|
Scolloped
|
A wide, shallow "U" shape that comes to a point. Useful as above but the points make it more aggressive. Useful on foam.
|
|
"V"
|
Really aggressive on foam. Instead of having one tooth every inch as Wavy or Scolloped there are 10 or 14 teeth every inch. Useful on foam.
|
|
"V" double edge
|
Same as above except there is no smooth edge. Useful for making intricate patterns requiring backing out. Useful on foam.
|
|
Carbide grit, Diamond grit
|
The application for these types is abrasive materials when nothing else will work. Diamond should not be used on ferrous metals because the affinity of the carbon
in the diamond and metal microscopically dissolves the diamond! Used on ferrous metals
|
|
Butcher and Fish band
|
A thin blade that is distinctively shiny and is not protected with any oils.
|
Cutting mild steel or annealed material you would want no less than 3 teeth touching the material or no more than 24. The ideal amount of teeth touching the material at one time would
be 6-12. When picking the correct tooth count you also want to consider the wall thickness too aggressive of a tooth count will case the teeth to get catch in the side walls and you
will break your teeth. Too fine of a tooth count will only cause a problem when you are cutting through the top or bottom of your material. This can cause premature blade wear
or motor failure.
Conditions that will influence pitch selection:
- Soft materials require less teeth and more gullet capacity.
- Hard materials require more teeth to share in the work and less gullet.
- Machine capabilities. Constant feed machines can use a coarser pitch. Gravity feed machines will require a finer pitch.
Please remember that there are Proper Techniques for All Types of Shapes.
Please Call 800-458-3687 for help in choosing the correct blade for you application.
Diagnosing Cutting Issues with Band Saw Blades
|
Premature and Excessive Tooth Wear
- Feed pressure too light, increase it Lower band velocity
- Improper tooth selection, use a finer pitch
- Improper break-in with new band. Velocity and feeding should be reduced the first few cuts
- Teeth are running the wrong direction. Be sure teeth are pointing in proper direction
- Incorrect saw guide insert size for the band, allowing them to strike teeth
|
Band Stalls in Work
- Feed pressure too great - decrease feed
- Teeth too coarse, use finer tooth blade
Blade Making Belly-Shaped Cuts
- Increase tension
- Adjust guides closer to work piece
- Teeth too fine - use a coarse pitch
- Decrease feed force
- Teeth dull
