Description of problem:
There is a smooth wear across the tips of the blade teeth and the corners of set teeth have become rounded.

Likely causes:

  1. Improper break-in procedure. Makes sure you follow the recommended process for breaking new blades in.
  2. Too-high band speed for the type of material being cut. If the band speed is too fast, the tip of the teeth experience a higher temperature which causes faster tooth wear.
  3. Too low feed rate of the material being cut. This causes teeth to rub instead of piercing the material and the prolonged abrasion wears the teeth. This is common on hardened materials such as stainless steel.
  4. Hard or abrasive materials being cut.
  5. Not enough sawing fluid.
