    Abstract: 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.

    Abstract: 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.

    Abstract: A support assembly for a core drill which utilizes an improved high strength spoked reinforcer. The reinforcer may be removably mounted a core drill tube by fasteners. A drive connection is removably mounted and centrally located on an outer disc of a pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube. The assembly can also include a split in the disc when the high strength spoked reinforcer is not welded thereto, thereby providing a means of water control. The high strength spoked reinforcer can be a separate piece that is bolted to the disc or can be integrally formed as one piece therewith.

    Abstract: A support assembly for a core drill uses an improved reinforcement. The reinforcement can include an extension extending between a center of the tool and a perimeter of the tool the extension can be a non-planar structure having a channel along a portion of the structure. The reinforcement can include a slanted element that can be associated with the extension, that can be formed monolithic with the extension, or otherwise combined with an extension. Multiple slanted elements can be used to form an extension. A top plate can be included for strengthening the reinforcement.

    Abstract: A sawmill includes a four-stroke internal combustion engine having an output shaft for driving a sawblade. The output shaft has a longitudinal axis. The engine is mounted on the sawmill for rotation between a first operative position with the longitudinal axis of the output shaft extending at a first angle, and a second operative position with the longitudinal axis of the output shaft extending at a second angle transversely to the first angle. The engine has fuel injection to facilitate operation in the first and second operative positions and a lubrication system incorporating a wet sump. An oil pick up for the lubrication system is configured to pick up oil from the wet sump at both the first and second operative positions.
