ABSTRACT:
In a desk-top circular saw comprising a base, a turntable mounted on the base, an arm provided on the rear of the base, and a saw blade assembly pivotally attached to the upper end of the arm with a pivot shaft, a horizontal cylinder is provided in the arm between the pivot shaft and a blade tilting lever. The cylinder penetrates the arm to allow airflow therethrough. Provided in front of the cylinder is a flared member including a bottom plate sloping downward and a pair of side plates, thereby forming a U-like cross section. A chip guide comprising an upper plate and side plates forming an inverted U-like cross section is fastened to the underside of the neck of the saw blade assembly. The chip guide can vertically pivot integrally with the saw blade assembly. The flared member and the chip guide jointly form a chip guide passage for guiding chips into the cylinder for disposal.
