In a circular saw, the centrifugal force acts to throw the sawdust out, while in a frame saw, the backward motion of the saw acts to clear the teeth of the dust, whereas in a band saw the dust is apt to pack in the teeth while they are passing through the work. The remedy is to space the teeth widely, thus giving room for the dust without having a deep tooth, an ordinary form of tooth being shown in [Fig. 3126].
Fig. 3127.
A stronger form of tooth is shown in [Fig. 3127], the tooth gullets being well rounded out, and the teeth shallow at the back, while having ample room in front for the dust.
