A power tool, such as a cast saw is disclosed. The cast saw is equipped with at least one thermocouple and and/or at least one infrared detector that measure the temperature of the cutting blade on the cast saw or the area in the cast immediately surrounding the cutting blade. The cast saw is also equipped with at least one LED that can alert a user of the cast saw when blade or the area in the cast immediately surrounding the blade is approaching or has reached a temperature that may burn a patient. Also disclosed is a shroud for the cutting blade of the cast saw. The shroud not only surrounds at least part of the blade but also houses the thermocouple or infrared detector and the LEDs(s). A method of operating the cast saw to cut a cast off of a patient is also disclosed.

A power tool includes a housing, a motor that is disposed within the housing and defining a first axis, and a tool holder driven to oscillate about a second axis by the motor. The second axis is perpendicular to the first axis. The power tool also includes a vibration dampening assembly with a counterweight that is configured to reciprocate along a third axis that is perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis.

An accessory for an oscillating power tool includes an anchor for selectively coupling with an oscillating power tool. The anchor includes a generally planar portion having an anchor interface configured to couple to the oscillating power tool and defining a longitudinal axis and a center point. The anchor interface includes a central aperture and a plurality of peripheral openings. The central aperture includes the center point therein. The plurality of peripheral openings are disposed radially about the center point and in communication with the central aperture. The plurality of peripheral openings also includes at least one conjoined group of peripheral openings collectively in communication with the central aperture by way of a shared neck opening. The at least one conjoined group includes a first peripheral opening, a second peripheral opening, and a third peripheral opening.

A power tool includes a spindle, a motor, an inner housing and an outer housing elastically connected to the inner housing. The inner housing is formed by a first inner housing portion formed of metal connected to a second inner housing portion formed of synthetic polymer. The first inner housing portion includes a housing part disposed in a front part of the outer housing, and a first extending part extending rearward from the housing part and disposed in a grip part of the outer housing. The second inner housing portion includes a second extending part that has a tubular shape and at least partially surrounds the first extending part, and a rear end part connected to the second extending part and disposed in a rear part of the outer housing. The first extending part extends rearward of a center of the second extending part in the front-rear direction.

Included are: a clamp configured to switch between a mounting state in which a tip tool is mounted and a releasing state in which the tip tool is removed; a clamp moving portion configured to move between a first position at which the clamp is in the mounting state and a second position at which the clamp is in the releasing state; a clamp urging portion configured to urge the clamp moving portion to the first position; a case accommodating at least a part of each of the clamp, the clamp moving portion, and the clamp urging portion; a retaining portion configured to retain the clamp moving portion at the second position; and a mounting operation portion configured to receive mounting operation for switching the clamp from the releasing state to the mounting state. When the mounting operation portion receives the mounting operation, the retaining portion cancels retaining of the clamp moving portion at the second position.

A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.

In some embodiments, a cutting system including a movable blade or a reciprocating blade operably coupled to a motor is disclosed, wherein the cutting system comprises a diverting feature. In some embodiments, a diverter proximity relative to the movable blade or reciprocating blade is selected to facilitate diversion of a material during cutting. In at least one embodiment, the movable blade may be movable blade for an oscillating tool. A cutting system according to the present invention may be coupled to a container, for example, a residential trash container or a residential recycling container.

An oscillating power tool has a housing including a handle portion defining a handle axis and a head portion defining an output axis that is perpendicular to the handle axis. The head portion includes a front face intersected by the handle axis. A drive mechanism includes an output shaft configured to oscillate about the output axis in a rotational manner in response receiving torque from a motor. A lighting assembly is configured to illuminate a workpiece in front of the head portion of the housing. The lighting assembly includes a lens arranged on the front face of the housing, a holder coupled to the lens, a plurality of printed circuit boards supported by the holder, and an LED arranged on each of the printed circuit boards. In response to being activated, the LEDs are configured to project a wide-angle beam of light through the lens.

A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.

A work tool includes a housing, a spindle, a clamp shaft, a biasing member, an operation member, a motion-converting mechanism and a pushing-down member. The spindle is supported to be rotatable around a driving axis. The clamp shaft is movable in the up-down direction relative to the spindle. The biasing member is configured to bias the clamp shaft upward relative to the spindle so as to apply to the clamp shaft a clamping force for clamping a tool accessory between a head part of the clamp shaft and a lower end portion of the spindle. The motion-converting mechanism is configured to move the pushing-down member in the up-down direction along with turning of the operation member around the driving axis. The pushing-down member is configured to be moved downward so as to push the tool accessory downward when the operation member is turned in a first direction.
