Abstract: In connection with a hand-operated power tool (10), in particular a hand-operated circular saw, with a machine housing and a base plate (11, 41) with a guide groove (18, 63) for overlapping a guide rib (17) of a guide rail (16) for the guided displacement of the hand-operated power tool (10) on a workpiece, the object of providing a precisely adjustable position of the guide groove with a small manufacturing outlay is attained in that the guide groove (18, 63) is disposed in a groove holder (21, 51) which is separate in respect to the base plate (11, 41), secured against loss, displaceable in at least one direction in the plane of the base plate (11, 41), particularly transversely to the guide groove (18, 63).

Abstract: A hand circular saw comprises a swinging protective hood, a housing which carries a saw shaft axis and a saw blade held rotatable about the saw blade axis, a base plate, the housing being arranged independently turnably relative to the base plate around two further axes extending substantially perpendicular to one another, a first of the further axes being parallel to the saw shaft axis for guiding a turning movement for adjusting a cutting depth and is adjustable on a cutting depth guiding bracket with a scale, while a second of the further axes extends both parallel to the base plate and also parallel to the saw blade for guiding a turning movement for adjusting a miter angle, the cutting depth guiding bracket having an angle-profile shaped cross-section and having at least one leg which is formed as a sliding guide supporting the housing in each cutting depth position.

Abstract: The eccentric grinder includes a housing, a fan wheel mounted rotatably in the housing and being rotatably driven in the housing during operation, an eccentric shaft mounted rotatably and eccentrically in the fan wheel, a grinding disk nonrotatably fixed in a central portion thereof with the eccentric shaft and an outer region of the grinding disk being arranged without connection to a remaining group of parts of the grinder and axially spaced therefrom; and at least one exchangeable reversible intermediate plate. Each of the intermediate plates can be mounted nonrotatably on the eccentric shaft between the grinding disk and the housing during operation in one of two positions. To cause a rotary motion of the grinding disk in addition to an eccentric motion one of the intermediate plates is provided with only one toothed or friction rim which is engaged in a fixed toothed or friction rim provided on the housing when the intermediate plate is installed in one of the two positions during operation.

Abstract: An electric hand plane has a wedge-shaped body having a lower wedge surface adapted to rest on a workpiece and an upper wedge surface, a plane housing supported on the upper wedge surface of the wedge-shaped body and having a counter-surface, a device for producing a clamping force between the upper wedge surface of the wedge-shaped body and the counter-surface of the housing, and a single handle operative for cancelling the clamping force during an adjustment and also for displacement of the wedge-shaped body, and a gear mechanism means arranged so that the handle displaces the wedge-shaped body relative to the plane housing via the gear mechanism means by rotation.

Abstract: A motor driven hand power tool has a saw including a saw blade, a separating tool formed as a saw blade movable about a tilting axis extending parallel to a cutting line of sight and fixable in each turning position relative to a workpiece which is subdivided by a cutting joint into a product-side and a refuse-side with product and refuse-side cutting edges, a base plate over which the saw blade is positioned. The saw blade is arranged so that the tilting axis extends at a distance under a lower side of the base plate, and the distance is dimensioned so that the tilting axis in a working position of the power tool is located under an upper surface of the workpiece in an interior of the workpiece.

Abstract: A power saw has a sword having side walls which form a groove-shaped guide, and two parallel oppositely reciprocable saw blades having one longitudinal side provided with saw teeth and another longitudinal side provided with backs which are guided in the groove-shaped guide. The groove-shaped guide is interrupted by a plurality of recesses.

Abstract: An eccentric grinder has a housing provided with a gear rim an eccentrically rotating grinding disc provided with a gear rim which rolls on the gear rim of the housing and in operation without load provides an additional rotary movement of the grinding disc. The gear rim of the grinding disc is a friction rim so that in operation without load there is a minimum slippage and in operation under load there is a maximum slippage of the rims relative to one another. The gear rim of the housing is fixed to the housing and includes a toothed rim which is formed by a ring-shaped toothed belt with a toothing while the gear rim of the grinding disc has a plurality of projections which incompletely engage in the toothing of the gear rim of the housing and therefore an elastic deformation of the projections gives the grinding disc a shaking movement with partial meshing under maximum slippage.

Abstract: The eccentric grinder includes a housing, a griding disk on which a grinding paper is held, an eccentric shaft on which the grinding disk is nonrotatably mounted and a mechanism for changing a grinding movement of the grinding disk having at least one fixed friction or toothed rim. At least one exchangable reversible intermediate plate (17,37) is provided for the grinder attachable to the eccentric shaft and each having at least one other friction or toothed rim (21,22). In operation, one of the intermediate plates (17,37) is placed between the housing (6) and the grinding disk (24), which, when engaging the fixed friction or toothed rim (34,35) with one of its friction or toothed rims (21,22), causes a rotary motion of the grinding disk (24) in addition to an eccentric motion.

Abstract: The angle stop has a supporting table pivotally but securably mounted on a stationary table carrier. Means for maintaining the edge of the supporting table facing the working plane of the machine tool at a constant distance relative to the working plane in every angular position of the supporting table are provided. This means includes two opposing side parts rigidly attached to opposite sides of the supporting table each having two opposing through-going openings or slots(guideways) and guide elements connected with the table carrier extending through the through-going openings for securing the supporting table releasably in a particular angular position and for guiding its pivotal motion. This improves the secure contact of workpieces and reduces the risk of accident due to workpieces being drawn into the gap between the contact table and working plane of the machine tool.

Abstract: An eccentric grinder having a small construction in the axial direction comprises an eccentric (15), which is driven so as to rotate, and a grinding plate (16) which is rotatably supported in the eccentric (15) and which can be set in rotation around its axis of rotation in one or the other rotating direction via rotating rings (26, 27), which are rigidly connected with the grinding plate (16), and via rolling rings (30, 31), which are arranged at the grinder housing (10), in order to change its grinding action. The selection of the rotating direction is determined by means of a manual switching device (38). For this purpose, the rolling rings (30, 31) are held at the grinder housing (10) so as to be rotatable and are in continuous engagement with the rotating rings (25, 26) fastened at the grinding plate (16).
