An accessory for use with an oscillating power tool includes an attachment portion having a first planar member, a second planar member parallel to the first planar member, a central opening defined in one of the first planar member and the second planar member, a keyed sidewall disposed at least partially around the central opening and extending from the first planar member to the second planar member transverse to the first planar member and to the second planar member, and a plurality of equiangularly spaced recesses defined in one of the first planar member and the second planar member, the recesses spaced apart from the keyed sidewall and not in communication with the central opening. A working portion may be couplable to the attachment portion and configured to perform an operation on a workpiece.

A dual sided drill bit system to facilitate the switch between a drilling tool and a screw driver tool includes a power drill that has a chuck. A receiver is removably coupled to the chuck. The receiver has an open end that extends into a cavity of the receiver. A bit is included that has a first section, a second section and a middle section positioned between the first and second sections. The first, second and middle sections form a unitary structure. The first section has a first end positioned opposite of the middle section and the second section has a second end positioned opposite of the middle section. The first section comprises a drill bit and the second section comprising a screw driver. The bit is removably extended into the receiver such that a selected one of the first or second sections extends outwardly away from the receiver.

It is an object of the invention to increase the degree of freedom in designing a power tool. A representative power tool 100 has a spindle 124 that transmits a driving force of a motor 115 to a tool accessory 145, a tool accessory holding member 127 that is configured to be movable in a direction of a spindle rotation axis direction 124a between a holding position for holding the tool accessory 145 and a releasing position for releasing the tool accessory 145, a lock mechanism 130 that locks the tool accessory holding member 127 in the holding position, and a body housing 101. The lock mechanism 130 is disposed between a second end 1241 of the spindle 124 and a wall of the body housing 101 in the spindle rotation axis direction 124a.

A method for setting up a rotary processing machine (1), in which at least one base jaw (4) of a workpiece receptacle is set up to receive a workpiece type that is to be processed and in which the base jaw (4) is coated on a workpiece contact surface (15).

An accessory for coupling to an oscillating power tool includes a working end portion and an attachment portion. The working end portion defines and extends along a working axis. The attachment portion is coupled to the working end portion and includes a top wall, a bottom wall spaced apart from the top wall, and a peripheral wall extending from the top wall to the bottom wall at least partially around the top wall to form at least a portion of a polygonal shape. A generally U-shaped opening is defined in the top wall, extends along an attachment axis at an angle to the working axis, has a central portion at a center of the attachment portion, and is open to a gap in the peripheral wall. A plurality of radial openings is defined in the top wall and arranged between the U-shaped opening and the peripheral wall. The peripheral wall, the U-shaped opening, and the plurality of radial openings are configured to couple the attachment portion to at least two different configurations of accessory attachment mechanisms on different oscillating power tools.

A clamp for selectively inhibiting movement of a first object relative to a second object includes (i) a first clamp component coupled to the first object; (ii) a second clamp component coupled to the second object; and (iii) a fluid source that directs a fluid to the second clamp component to create a fluid bearing between the first clamp component and the second clamp component that allows for movement of the first clamp component relative to the second clamp component, and wherein the fluid source directs less fluid to the second clamp component to inhibit relative movement.
