摘要： A carrier is connected to the plunger for reciprocating therewith; the carrier is of inverted U-shape defining a recess open at its bottom. A holder is pivotally mounted to the carrier for swinging movement back and forth between a first position wherein the holder is substantially nested within the recess in the carrier and a second position wherein a substantial portion of the holder extends out of and away from the carrier recess. The holder is also of inverted U-shape defining a cavity for receiving a portion of a contour sanding member. Detent elements on the carrier compress the holder when the latter is in its first position thereby to impart a clamping force to a contour sanding member received within the cavity of the holder. A manually operated ejection member mounted on the tool housing engages the holder for moving the same from its first position to its second position.

摘要： A portable circular saw with a 60.degree. bevel cut capability that is provided by a combination of blade diameter, height of front and rear pivot points above the footplate, the ability to tip the saw about a front hinge point to avoid projections contacting the footplate at a 60.degree. angle and recesses and orifices provided in the footplate at points where interference would normally occur between the motor housing assembly and the saw blade when the blade is at a 60.degree. bevel angle so as to prevent any interference of the footplate with the motor housing assembly and saw blade. A positive stop is provided at angles of 45.degree. and 60.degree..
