There is disclosed an improved bevel angle setting means for supporting and pivoting the motor-driven tool supporting assembly of a power tool apparatus including a housing equipped with a table top having an opening through which the motor-driven tool, such as a circular saw, extends; the improvement comprising means for supporting and pivoting the assembly about a pivot axis in a rapid manner whereby the bevel angle is varied. The pivoting means include a bevel handle secured to the assembly frame and a counterbalance means such as a "gas spring," which will be more fully explained hereinafter. The gas spring will act to assist the operator in adjusting the bevel angle setting for both increasing or decreasing of such bevel angle settings.
