A hand power tool has a housing with having at least two housing parts. A sealing element provides mounting of the housing parts on one another fluid-tightly. The housing parts have short sides with which the housing parts abut against one another with interposition of a sealing element. The sealing element is fixed on one of the housing parts.

Sealing element for housing of a hand power tool

A circular power saw (), composed of a saw assembly () with a housing () that encloses a motor and a saw blade () capable of being driven by the motor, and that includes a handle, whereby the saw assembly () is pivotably supported relative to a footplate () such that it can be adjusted between a minimum and maximum cutting depth, is protected against kickback by the fact that, during sawing, the saw assembly () is decoupled from handling forces acting on the saw blade (), in particular from the handle ().

Hand-held circular saw

An electrical manual power saw includes a machine housing that has a housing shaft and a housing head ( ) holding an interchangeable tool, and an electrical drive for driving the tool in an oscillating reciprocating motion. The housing shaft, for the sake of attaining an ergonomically defined gripping position in the vicinity of an on/off switch, has a rod-like shape, and in the transition region between the rod-shaped housing shaft and the housing head, a construction is provided. The on/off switch is disposed laterally offset on the housing head, below the axis of the shaft in such a way that when the constriction is grasped by a hand of a user the thumb of the grasping hand rests on its actuation knob.

Cutting blade

Close cut saw

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.

A motor driven hand circular saw has a base plate arranged to be positioned over a workpiece, and a saw blade which is displaceable parallel and tiltably about a turning axle relative to the base plate for performing inclined or bevel cuts so that by tilting of the saw blade relative to the base plate about the axle, the saw blade and the axle are displaced parallel to the base plate with a stroke which is proportional to a respective tilting angle transversely to a direction downstream of a cutting point and counteracts a natural displacement of a saw engaging line of the saw blade on the workpiece.

Fixture for a wire for use in a winding process in a manufacturing of electric machines. The fixture includes a groove-shaped wire-receiving element and is provided with a funnel-like slot extending at an angle to the axis of elongation of the wire-receiving element. The wire end inserted into the wire-receiving element is then guided through the insertion slot.
