ABSTRACT:
The specification discloses a motor housing, with a handle of the circular saw type, and a cantilever saw bar carrying a saw chain is secured to the housing in a position extending downwardly from a guide foot of the housing. A retractable guard bar normally is held in a position holding a guard loop around the nose end of the saw bar, the guard bar being positioned at the rear of the saw bar. The guard bar is mounted slidably on the motor housing, and, when a latch is manually released, the guard loop may be pushed up along the saw during a boring (nose cutting) operation. In an alternate embodiment, a foot attachable to a foot of a circular saw motor carries a saw bar and a guard bar with a guard loop surrounding the nose end of the saw bar.
