Description of problem:
To determine if the band broke at the weld, inspect the sides at the fracture to see if there are grind markings from the weld finishing process.

Likely causes:

  1. When running Bi-Metal blades at high speeds like a wood machine runs breaks can occur easily. Band saws designed for wood working run at high speeds and are running a carbon blade that has more flex.
  2. Any of the factors below can also cause body breaks and butt weld breaks.
