发明名称 Dust shroud for pipe-cutting portable circular saw
摘要 A dust shroud is disclosed for a pipe-cutting portable circular saw. The shroud comprises upper and lower blade housings which are nested and guided so that the lower housing can be moved into and out of the upper housing. The lower periphery of the lower housing generally conforms to the shape of the pipe to be cut. A device which cooperates with the saw and which fits into the pipe to collect dust from within the pipe is also described.
