Abstract: A hand-held jigsaw machine includes a machine housing (11), a saw blade (13) that is drivable in a reciprocating manner by a motor, a support device (20) with a support roller (23) that supports the saw blade on its back (132), and a holder (22) that is fixed to the machine housing (11) and accommodates the support roller (23) between two arms (222, 223), and a guide device (21) for guiding and supporting the saw blade (13) transversely to the saw direction with guide elements (24, 25) on opposite sides of the saw blade (13) at an adjustable distance from each other. To ensure economical production of the support and guide device and to reduce the number of components required, the guide device (21) is integrated in the holder (22) of the support device (20).

Abstract: A clamping device for toolless clamping of saw blades equipped with the clamping shank for a hand machine tool has two clamping parts that are pressable against each other. Each of the clamping parts is provided with a support surface for the clamping shank of a saw blade insertable between the clamping parts. At least one of the clamping parts is movable in relation to the other of the clamping parts in order to clamp and release the clamping shank. An independent actuating element is movable by hand and provides a sliding movement or a rotating movement.

Abstract: A base plate (20) for a power scroll saw is disclosed, which has a through opening (15) for a saw blade (13) that is drivable in a reciprocating motion by the power scroll saw. To prevent defective straight cuts and laterally obliquely extending cuts, especially in thick material to be cut, from lateral deflection of the tip of the saw blade in sawing, a guide device (21) with guide elements (22, 23) protruding into the through opening (15) is integrated with the base plate (20). With power scroll saws that have no guide device for laterally guiding the saw blade (13), an improved outcome of sawing can be attained by simply replacing its base plate for the novel base plate (20) disclosed here (FIG. 2).

Abstract: In a marking device having a laser and a fastening element, especially simple, fast and precise marking of workpieces is attained by providing that the marking device includes a goniometer.

Abstract: A hand-held jigsaw machine is described that includes a machine housing (11), a saw blade (13) that is drivable in a reciprocating manner by a motor, a support device (20) with a support roller (23) that supports the saw blade on its back (132), and a holder (22) that is fixed to the machine housing (11) and accommodates the support roller (23) between two arms (222, 223), and a guide device (21) for guiding and supporting the saw blade (13) transversely to the saw direction with guide elements (24, 25) on opposite sides of the saw blade (13) at an adjustable distance from each other. To ensure economical production of the support and guide device and to reduce the number of components required, the guide device (21) is integrated in the holder (22) of the support device (20).

Abstract: A hand power tool (10) that can be folded in its longitudinal span, having a housing base body (12) that holds the driven tool insert (14, 15) and whose axis is adjustable—relative to the axis of a housing part (11) serving as a handle—around a folding axis (13), is made especially compact and lightweight in that the hand power tool (10) is embodied in the form of a universal saw that has the ability to be locked in various angular positions of the housing parts (11, 12) relative to one other; the housing part (11) contains the drive motor (19), whose driven rotary motion is transmitted via an angle transmission (23, 35) to the tool insert—a saw blade (13, 14)—that is guided in the housing base body (12).

Abstract: An electric power tool (10) having a housing (12) from which a power cable (22) leads, is safer for the user because the circumference of the power cable (22) has lighting means (21, 26, 28, 30) along its longitudinal span, whose light makes the power cable (22) easily visible to the human eye in the dark.

Abstract: A power scroll saw with a housing and a saw blade capable of being driven in a reciprocating manner, and with tongs-like guides that guide the saw blade in a laterally-supported manner is capable of being used in a variety of work applications due to the fact that the guide means are capable of being switched by hand selectively into a position having lateral clearance from the saw blade and into a position in which they laterally support the saw blade.

Abstract: A power compass saw with a housing that accommodates a lifting rod for the up and down movement of a longitudinal saw blade attached thereto, has a toothed side and a saw blade back and with a guide roller which supports the saw blade back and has a central groove into which the saw blade extends with its saw blade back and is guided therein, the central circumferential groove has tapered groove sides with a 5° taper, the saw blade back has a straight portion and an end beveled portion with beveled edges having a 7° taper at both sides, the saw blade back has diametrically opposed edges provided at a transition from the straight portion to the beveled portion, and the saw blade back has a width which is measured between the diametrically opposed edges and is greater than a width of a bottom of the circumferential groove.

Abstract: A hand-guided power reciprocating saw has a machine housing, a saw blade drivable by a motor into a stroke motion, a guide device having two guide elements resting against the saw blade at opposite sides of the saw blade and operative for guiding and supporting the saw blade crosswise to a sawing direction, the guiding device further having a two-armed pivot lever with lever arms on each of which a corresponding one of the guide elements is situated, the guiding device also having an adjusting mechanism for adjusting a transverse spacing between the guide elements, a holder in which the guide device is integrated and which is configured to be mounted in the machine housing and/or to a base plate attached to the machine housing, the pivot lever being pivotally supported on the holder and the adjusting mechanism being accommodated in the holder.

Abstract: A clamping device for toolless clamping of saw blades equipped with the clamping shank for a hand machine tool has two clamping parts that are pressable against each other, each of the clamping parts being provided with a support surface for the clamping shank of a saw blade insertable between the clamping parts, at least one of the clamping parts being movable in relation to the other of the clamping parts in order to clamp and release the clamping shank, and an independent actuating element that is movable by hand and providing a sliding movement or a rotating movement.

Abstract: A power compass saw (10) with a housing (12) that accommodates a lifting rod for the up and down movement of a longitudinal saw blade (27) attached thereto, the saw blade having a toothed side and a saw blade back (270), and with a guide roller (29) which supports the saw blade back (270) and has a central circumferential groove (290) into which the saw blade extends with its saw blade back (270) and is guided therein, whereby the sides of the circumferential groove (290) are tapered, the power compass saw functioning particularly precisely and efficiently due to the fact that the saw blade back (270) of the saw blade (27) is designed with a 7° conical configuration and/or taper on both sides, so that it tapers toward the saw blade back (270) and is capable of being supported in two dimensions in the circumferential groove (290), the groove sides (291) of which have a 5° taper.

Abstract: A power scroll saw (10, 100) with a housing (12, 120) and a saw blade (18, 180) capable of being driven in a reciprocating manner, and with tongs-like guide means (26, 260) that guide the saw blade (18, 180) in a laterally-supported manner is capable of being used in a variety of work applications due to the fact that the guide means (26, 260) are capable of being switched by hand selectively into a position having lateral clearance from the saw blade (18, 180) and into a position in which they laterally support the saw blade (18, 180).
