20090160138 | Tool holder for a machine tool, in particular for a hand-held power tool - A tool holder for a machine tool has a tool holder element in which an insertion tool is insertable and lockable, a locking device for locking the insertion tool in said tool holder element and including a locking element displaceable between a release position and a locking position in which the insertion tool is locked in the tool holder, a blocking element held in the tool holder element and displaceable by the insertion tool, the blocking element inhibiting a motion of the locking element in a locking position, a control element which displaces the blocking element and located on the tool holder, which in a first phase when the control element moves between the release position and the locking position in a control position in which it acts on the blocking element, and in a second phase the control element is in a non-operational position, the control element is configured so that it performs an axial motion in the control position and it performs a radial motion to move it into a non-operational position. | 06-25-2009 |
20100213676 | TOOL SYSTEM - The invention relates to a tool system which includes an exchangeable rotary tool for electric hand-held machine tools, preferably with a drill and/or hammer function, in particular for an electric hammer drill, and an electric drill, in particular a percussion drill. The tool system also includes at least two tool holders that are embodied as tool fittings that are associated with the hand-held machine tools and are different types. The rotary tool has an insertable shaft to be accommodated in the respective tool holder of the hand-held machine tools, the shaft having at least two slaving ribs that are diametrically opposed and that extend along the shaft for rotational engagement. The tool fitting of a first type is embodied as a positive fit fitting and another tool fitting of the second type as a multi-jaw clamping chuck. The slaving ribs have a width and a height such that, in the clamped state, they are at a lateral distance from the clamping jaws of the multi jaw clamping chuck. | 08-26-2010 |
20110139472 | METHOD OF MACHINING WITH TOOL UNIT - A method of machining includes using a tool unit for a handheld power tool having an oscillating output unit, a fastening element for attachment to the output unit, and a working edge transitioning into a lateral boundary line, being arc-shaped, and constituted by a circumference of a circle around whose circle point the fastening element is situated, situating at least one end of the working edge at an angle of substantially 90° in relation to a lateral boundary line on at least one side and constituting the working edge by a circumference section of a circle sector, situating each of two ends of the working edge at an angle in relation to a respective lateral boundary line extending in a radial direction, and in a vertical guide as the tool unit advances along the lateral boundary line situating a deepest point of an advancing motion is situated in a corner between the arc-shaped working edge and the lateral boundary line, and so that between a bottom of the guide and the lateral cut edge there is not any residual cross-section of the workpiece. | 06-16-2011 |
20120144971 | Tool fastenable to a drive shaft of a hand-held power tool driveable in an oscillating manner - A tool is configured with a centering element and a fastening portion with form-locking elements for axial mounting and fastening onto a drive shaft of a hand-held power tool. The centering element and the form-locking elements are arranged in a first tool part. The form-locking elements are located radially outside the centering element and are configured with a quadrangular cross section that corresponds to a trapezoidal cross section, which is perpendicular to an axis of the drive shaft. | 06-14-2012 |
20120193115 | TOOL HOLDER FOR A ROTARY HAMMER - A tool holder for a hand-guided drilling device, in particular for a rotary hammer, includes a receiving sleeve that is designed as a single piece and that is drivable in a rotating manner for a shank part of an insertion tool. The recess is open at both end faces and limited therebetween by an inner circumferential surface of the receiving sleeve. The inner circumferential surface ( | 08-02-2012 |
20140123825 | TOOL FASTENABLE TO A DRIVE SHAFT OF A HAND-HELD POWER TOOL DRIVEABLE IN OSCILLATING MANNER - A tool for use with is configured with a tool centering element and a fastening portion with form-locking elements for axial mounting and fastening onto a drive shaft of a hand-held power tool. The drive shaft is drivable in oscillating fashion and the centering element centers the tool relative to the drive shaft. The tool form-locking elements define a rotary position of the tool relative to the drive shaft. The centering element may be a through-hole in a fastening portion of the tool or, may be a fastening screw that passes through an axially centered through hole in the fastening portion to the tool for securing the toll and fastening screw in a bore within the drive shaft to which the tool is attached for intended operation. | 05-08-2014 |
