In a portable circular saw depth of cut adjustment is effected by pivoting movement between a shoe (which supports the saw on a workpiece) and a motor and gear case housing (carrying the saw blade) about a pivot connection rearward of the motor and gear case housing. Forward of the housing an upwardly extending arcuate depth slide, fixed to the shoe, slidably engages an arcuate depth guide carried by the motor and gear case housing. Towards the upper end of the depth slide, and in generally fixed relation to it, a clamping assembly selectively clamps the depth slide and depth guide together to establish a depth of cut adjustment setting. The essentially fixed relationship of the locking knob of the clamping assembly to the shoe mean that the operations of changing depth adjustment setting may be made without changing operator's hand positions on the saw. In addition, the fixed position of the knob in sawing operations mean that by design, suitably shaped, sized and positioned, it may be used as an auxiliary handle in guiding the saw in sawing operations.
