Abstract:

A new tooth form for a welded edge band saw, which has a positive rake angle and an enlarged gullet space, while maintaining a large wedge angle, is disclosed. The tooth geometry has a wedge angle greater than positive rake tooth forms of previous design and a gullet space comparable to a zero rake angle standard tooth form. The new tooth form provides an improved cutting rate and useful life and it is particularly advantageous in connection with high speed heavy duty band saw apparatus.
