Abstract: A dust suction device (2), particularly in the form of an industrial vacuum cleaner, has a blower device (6) for generating an intake flow (S), a filter surface (16) for separating dust and dirt particles from the intake flow (S), a collecting chamber (18) for collecting the dust and the dirt particles which is located upstream of the filter surface (16) with respect to the intake flow (S), a clean air chamber (20) which is arranged downstream of the filter surface (16) and is separated from the collecting chamber (18) by the filter surface (16), with the filter surface (16) being acted upon in some areas by a cleaning flow of the blower device (6) which flows through the filter surface (16) in the direction opposite the direction of the intake flow (S), and an adjustable dividing wall (30) provided in the clean air chamber (20) and separating a vacuum area (40) that can be generated by the blower device (6) from an overpressure area (38) that can likewise be generated by the blower device (6).

Abstract: A hand-held band saw includes a motor (13) located in a housing (11) for displacing a circumferentially closed saw band (12) displaceable between a motor-driven driving roller (14) and a deflection roller (15) arranged, respectively, in first and second saw parts (21, 22) which are connected with each other by a bracket element (20), with the saw band (12) having two band sections (121, 122) displaceable parallel to each other and next to each other in an operational region (19) located between the deflection and driving rollers (14, 15). The band sections (121, 122) define together a cut width (S), and the bracket element (20) has, in the operational region (19), a width (B) that corresponds at most to the cut width (S).

Abstract: A circular saw blade has a guide plate (11), a plurality of pendulum-like cutter carriers provided at a circumferential outer region (12) of the guide plate (11), and cutters (21, 22) provided at radially outer ends (17) of the cutter carriers (14), respectively, the cutter carriers (14) being secured at their radially inner ends remote from the cutters (21, 22) to the guide plate (11) with a plurality of fastening elements (15) for pivotal movement in a plane defined by the guide plate (11).

Abstract: A hand-held circular saw (10) includes a housing (11); a drive (13) located in the housing for driving a circular saw blade (12), a cover element (15) for at least partially covering a working space (14) for the circular saw blade (12) and which defines a working plane (W), first and second main handles (21, 22) located opposite each other, and first and second switches (23, 24) provided on the first and second main handles (21, 22) respectively, for turning the drive (13) on and off.

Abstract: A circular saw stand (2) for effecting cuts with a hand-held circular saw (4), includes a device (6) for securing the circular saw stand (2) on a work table (10), a locking device (12) for adjustably defining a region (14) for receiving a to-be-cut workpiece (16) and having two clamping elements one of which is connected with the securing device (6) and another one is located opposite the one clamping element and displaceable relative thereto, and a guide device (42) forming a guide plane for a bearing plate (40) of the circular saw (4) and supported on one of the clamping elements.

Abstract: An electrical hand-held saw includes a saw blade (14) projecting from an end side (6) of the saw housing (4) and reciprocating along a stroke direction (H) that substantially extends in a direction of a longitudinal extent of the housing (4) limited by the end side (6), and a suction device (16) securable on the housing (4) and having a bearing region (22) adjoining the end side (6) of the housing (4) and a suction opening (54) for removing material particles produced during operation of the saw.
