Abstract: The invention provides a rotary tool system and method of operating. In one embodiment, a rotary tool system includes a rotary tool with a rotary motor, an output shaft operatively connected to the motor for transferring rotational force from the motor and a first coupler assembly, a flexible power transmission shaft including a first end portion with a second coupler assembly configured to removably couple with the first coupler assembly, a transfer shaft operatively coupled with the output shaft for receiving rotational force from the output shaft, and a third coupler assembly located at a second end portion of the flexible power transmission shaft and at least one implement, the at least one implement including a fourth coupler assembly configured to removably couple with the second coupler assembly and an input shaft operably connected to the transfer shaft for receiving rotational force from the transfer shaft.

Abstract: 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.

Abstract: 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..
