An illuminated tool bit assembly for illuminating a work area for a drill without casting a shadow includes a tool bit that can be inserted into a chuck of a power drill. The tool bit has a well integrated therein for insertably receiving an additional tool bit. A cylinder is provided and the tool bit extends through the cylinder. A lighting unit is integrated into the cylinder to emit light outwardly from the cylinder when the lighting unit is turned on. In this way the lighting unit can illuminate the work area without casting a shadow.

Handheld power tool having a housing with a machining axis along which a tool is or can be arranged, and having a lighting device that has at least one activatable lamp, the lighting device generating work light within a beam angle with an increased or maximum light intensity in a main emission direction in order to illuminate a work region, and having at least one light sensor for measuring the light intensity, characterized in that the light sensor detects the light intensity of the work light reflected on the work region during operation and generates control signals representing the light intensity, in that an adjustment unit is provided for setting and/or adjusting the work light generated by the lighting device, and in that a control unit is provided which controls the adjustment unit on the basis of the sensor signals during operation.

The present invention is a novel lanyard system for a piece releaseably connected to a tool by a piece receiver that includes a lanyard assembly with a two ended strap and a retraction system fixed to the tool in a storage region of the tool. In particular, one end of the strap is connected to the piece and the other strap end is connected to one end of the retraction system. The other end of the retraction system is connected to the tool. The strap is of sufficient length for the retraction system to retract a piece to the storage region after disconnection from the piece receiver. It is contemplated that the retraction system includes at least one spring (coil or helical) to cause the lanyard system to remain under tension while the piece is mounted in a piece receiver, thereby preventing or at least reducing the strap from interfering with the task at hand, the piece, the piece receiver or tool itself. The retraction system has sufficient tensional force to cause the retraction of a piece to the storage region once released from the work region of the tool.

The device disclosed herein allows a user to maintain the outboard stabilator of a Blackhawk helicopter. The device, which comprises a kit, allows a user to remove damaged outdoor stabilator bushings from a Blackhawk. Upon removal, the device enables a user to install new outdoor stabilator bushings. Additionally, the device allows a user to ream the newly installed outdoor stabilator bushings so that the outboard stabilator may be reinstalled upon the Blackhawk and safely flown.

A tool support is disclosed including-a fixed part, a moving part that is movable relative to the fixed part, a first crossmember linked to the moving part and a second crossmember. A tool includes a tool axis linked to the first and second crossmembers by pivoting links including articulation axes. A pointer is provided with a pointer axis parallel to the tool axis, the pointer being linked to the first and second crossmembers by pivoting links including articulation axes, with the articulation axes being parallel to one another. The tool support includes an immobilizer of occupy a first immobilized state in which it prevents a rotational movement on at least one articulation axis and a second released state in which it allows rotational movement on the articulation axes.

A dust collector for use with a power tool comprises a housing, a telescoping suction pipe coupled to the housing, a suction fan positioned in the housing and operable to generate a vacuum in the suction pipe, a dust container coupled to the housing and positioned upstream of the fan, a filter at least partially arranged in the dust container, and a filter cleaning mechanism. The filter cleaning mechanism includes an anvil, a striker moveable between a first striker position, in which the striker is spaced from the anvil, and a second striker position, in which the striker is in contact with the anvil. The filter cleaning mechanism further includes an actuator moveable between a first actuator position and a second actuator position, in which the actuator is moved closer to the anvil than in the first position, and a first spring biasing the striker toward the anvil.

A tool device comprises a first module and a second module that can be detached from the first module, the first module having a receptacle and the second module having an insertion part that can be inserted in the receptacle along an insertion axis. The insertion part can be rotated in the receptacle about the insertion axis between a locked position and an enabled position, the receptacle having a first projection and the insertion part having a second projection. In the locked position, the second projection engages behind the first projection in the direction of the insertion axis, and in the enabled position, the first projection enables the second projection to pass in the direction of the insertion axis, the receptacle preventing an activation of the tool device in an initial position and allowing activation of the tool device in a pressed-on position.

The invention relates to a deflector attachment (1), which is designed to be arranged on a predetermined drilling tool (111) having a predetermined drilling needle (19) which can be supported and guided along a drill axis (b) and which protrudes out of a housing (12) of the drilling tool (111) at the front. The deflector attachment (1) can be arranged on the front face of the drilling tool (111) and has a deflecting housing in which, in an arrangement for use, the drilling needle (19) emerging from the housing (12) of the drilling tool (111) can be guided. In the arrangement for use the deflecting housing is curved by a predetermined angle (a) and provides a drilling needle exit axis (a) which is offset by the predetermined angle (a) in relation to the predetermined drill axis (b) of the drilling tool (111). The invention further relates to a drilling device having a deflector attachment according to the invention, to a conversion set for drilling devices, and to a method for carrying out drilling or drill resistance measurements at a predetermined location of an object using the drilling device with deflector attachment.

A drill column end section assembly for a drill stand, comprising an end section (110) and a feed unit stopping element (120) arranged movable between a first position and a second position, wherein the stopping element (120), when in the first position, is arranged to prevent a drill stand feed unit from traversing past the drill column end section assembly, and, when in the second position, is arranged to allow the drill stand feed unit to traverse past the drill column end section assembly. The drill column end section assembly also comprises a positioning element (130) configured to releasably hold the stopping element (120) in the first position.

The present disclosure relates to a tool holding arrangement (1, 1′, 1″) comprising a rotatable shaft (2, 2′, 2″) which is at least connectable to a tool driving power source (3) and comprises a first shaft thread (4, 4′). The tool holding arrangement (1, 1′, 1) comprises a thread insert (5, 5′) that comprises a first insert thread (6, 6′), adapted to engage the first shaft thread (4, 4′) so as to form a first thread arrangement (4, 6; 4′, 6′). The thread insert (5, 5′) comprises a second insert thread (7) that is adapted to engage a tool thread (8) of a tool holding device (9) that is arranged to be 2 screwed onto the second insert thread (7) so as to form a second thread arrangement (7, 8), the first thread arrangement (4, 6; 4′, 6′) having a higher pitch than the second thread arrangement (7, 8).
