The present disclosure relates to a saw, comprising a drive, a first blade configured to oscillate about an axis perpendicular to a plane defined by a surface of the first blade, a second blade configured to oscillate about an axis perpendicular to the plane in a direction opposite to that of the first blade, and wherein gearing is provided between the drive and the first and second blades to reduce the speed transmitted from the drive to the blades. A saw blade, a connection mechanism for connecting a blade to a saw and associated methods are also provided.

A power tool includes a housing (10), a spindle (4) supported in the housing to be pivotable or rotatable about a driving axis, a clamping shaft (60) that is selectively movable in the up-down direction relative to the spindle, a biasing member (70), a release member (71) and an actuating member (50). The release member is selectively movable in the up-down direction relative to the spindle and is configured to selectively interrupt transmission of upward biasing force from the biasing member to the clamping shaft. The release member is also configured to be locked to the spindle in a locked position while transmission of the biasing force is being interrupted. The actuating member is movable upward in the up-down direction relative to the spindle in response to being pressed upward by a clamping part (64) or by a tool accessory (91) to thereby unlock the release member from the spindle.

An accessory for an oscillating power tool that oscillatingly drives a removably attachable output element. The accessory includes an attachment portion configured to be removably attached to a housing of the oscillating power tool on a side of the output element that faces the housing. The attachment portion is at least partially annular and defines an axial opening therethrough. The attachment portion includes a circumferential inner surface defining the axial opening and a circumferential outer surface opposite the inner surface. The attachment portion is configured to snap-fit with the power tool housing.

A power tool system comprises a power tool and a dust collection attachment. The dust collection attachment comprises an attachment portion mounted on the power tool and a dust collection tube extending alongside the attachment portion. The dust collection attachment comprises a tab configured to retain the dust collection attachment on the power tool and arranged on the dust collection tube. The power tool comprises a pocket in which the tab is located.

The invention relates to a tool device which is suitable for use with a machine tool, in particular a hand guided machine tool, having a driving device moving, in particular in an oscillating manner, around a driving axis. The tool device has an attachment device which allows it to be fastened on a machine tool such that its driving axis and an axis of rotation of the tool substantially coincide. The attachment device, for absorbing the driving force, has at least two driving area regions, which are spaced apart from said tool axis of rotation and each has a plurality of surface points. The tangent planes to said surface-area points are inclined in regard to an axial plane, which encloses the tool axis of rotation. Furthermore, said tangent planes are inclined regard to a radial plane which extends perpendicularly to the tool axis of rotation. This means that the torque introduced into the tool device by the machine tool, via the driving device, is reliably absorbed.

A power tool includes a spindle, holding members each having a claw, a biasing member, and a locking member. The holding members are movable between a first position, in which the holding members fixedly hold a tool accessory against a tool mounting part of the spindle with the claws pressed against the tool accessory owing to a biasing force of the biasing member, and a second position, in which the holding members do not impede or block attachment or detachment of the tool accessory. The locking member is configured to move between a locking position, in which the locking member abut on the claws of the holding members to hold the holding members in the second position, and an unlocking position, in which the locking member does not impede or block the holding members from moving from the second position to the first position.
