To provide a bench circular saw capable of always displaying an accurate angle by making it possible to always detect, operate and store the angle of revolution of a turntable and detecting and storing the angle even if the turntable is revolved in a state that a main power supply is not turned on to display the stored angle when the main power supply is turned on next time.

A quantity-of-revolution detecting unit 51 for detecting the quantity of revolution of the turntable with respect to a base is provided on the turntable and a quantity-of-tilting detecting unit for detecting the quantity of tilting of a tilting part 74 with respect to the tilting support part 71 supported on the turntable is provided to the tilting part 74 for supporting a cutting part. An RAM for storing the detected quantity of revolution and the quantity of tilting and a microcomputer for operating an angle of revolution and an angle of tilting are arranged in front of a neck stand part 23 and a battery box 132 is provided in the arcuate recessed part 24 of the turntable. The quantity-of-revolution detecting unit 51, a quantity-of-tilting detecting unit and the microcomputer are wired to receive the supply of power.
