A power tool may include a body arranged to support a rotatable work tool. The body may include a front handle and a rear handle. The front handle may be arranged between the rotatable work tool and the rear handle. The power tool may further include a liquid dispensing system for adding a controlled amount of liquid to the rotatable work tool. The liquid dispensing system may include a valve for adjusting a flow of liquid in the liquid dispensing system. The valve may include a control member arranged on a portion of the body separate from the front handle but adjacent to the front handle such that the control member is operable by a hand gripping the front handle.

Power tool with improved liquid dispensing system

A hand-held work tool () comprising a first part () and a second part () arranged vibrationally isolated from each other, the first part () comprising an interface for holding a circular cutting tool () and an electric motor () arranged to drive the circular cutting tool, wherein the electric motor () is arranged to drive a fan () configured to generate a flow of cooling air for cooling the electric motor (), the second part () comprising a battery compartment () for holding an electrical storage device arranged to power the electric motor (), wherein a cooling air conduit is arranged to guide a portion of the flow of cooling air () from the first part () and into the second part () for cooling the electrical storage device.

Hand-held electrically powered work tool

A cutting and dust or slurry collecting assembly that comprises: a) a circular saw blade () b) a blade guard () c) a cover device (), and the cover device () has a front end (), a rear end (), a top surface (), a bottom surface (), elongated sidewalls (), and a longitudinal passage () for the saw blade, d) the blade guard () and the cover device () being pivotally connected or connectable to one another via a hinge () in or adjacent to a lower rear corner of the blade guard (), such that the cover device and the blade guard can be turned in relation to each other, e) a discharge member () is provided at the rear of said hinge and has an outlet () which can be connected to a vacuum source, f) a connection member () connects the discharge member () with at least one of the longitudinal passage () and the cut created rear of the longitudinal passage, g) that the direction of rotation of the saw blade () is such that a circumferential part of the blade which has passed beyond the bottom surface of the cover device will move in a direction upwards-rearward towards the bottom surface In particular a rear arm distance (LR) between the hinge () and the rear end () is bigger than 0.2 R and preferably bigger than 0.25 R, thereby enabling a turning of the cover device () by pressing the rear end () towards the structure to be cut.

Cutting and dust or slurry collecting assembly and working machine

The present disclosure relates to a drill tool (), such as a core drill tool (), comprising a motor unit () and a gear unit (). The motor unit () comprises an electric motor () and a motor drive shaft () that extends along a first longitudinal axis () from the electric motor () and protrudes out of a motor unit housing () via a motor exit aperture () in a housing end part () and comprises a drive shaft gear (). The drive shaft gear () is adapted to propel a drill shaft () that extends along a second longitudinal axis () and comprises a tool holder () that is adapted to hold a tool. The housing end part () comprises a wall part () arranged transversally to the longitudinal axes () and is adapted to close the gear unit cavity () and to separate the electric motor () from the gear unit cavity ().

Drill unit with a motor unit and a gear unit

The present disclosure relates to a cutter clamp () that comprises a first arm part () and a second arm part (), where the arm parts () are arcuate and arranged to adjustably at least partially enclose a major part of a circumference () having a center (). The cutter clamp () comprises at least one hollow rod () arranged for receiving a mounting rod () for a power cutter () in a pivoting manner. The smaller circumference the arm parts () are adjusted for, the closer to the center () said hollow rod () is moved. The present disclosure also relates to a cutter clamp attachment device (), a cutter clamp kit and a cutter clamp holding frame ().

An electric power saw/cutter includes a rotatable saw structure, a rear handle with a switch/speed control, a front handle, and a drive unit for rotating the saw structure. The drive unit includes a saw structure drive arrangement to which the saw structure is attachable, a transmission for driving the saw drive arrangement, an electric motor for driving an input shaft of the transmission, and a support structure for holding/carrying the saw structure drive arrangement. The transmission and the electric motor may be characterized in that the front handle and the rear handle are directly connected to each other to form a handle unit, which unit is resiliently connected to the drive unit, so that vibrations from the saw blade and drive unit will be reduced in the handle unit.

Electric cutting system

A cutting and dust or slurry collecting assembly that includes: a circular saw blade, a blade guard, and a cover device. The cover device has a front end, a rear end, a top surface, a bottom surface, elongated sidewalls, and a longitudinal passage for the saw blade. The blade guard and the cover device are pivotally connected or connectable to one another via a hinge in or adjacent to a lower rear corner of the blade guard. A discharge member is provided at the rear of the hinge and has an outlet which can be connected to a vacuum source. A connection member connects the discharge member with the longitudinal passage and the cut created rear of the longitudinal passage.

An electric power saw/cutter includes a rotatable saw structure, a rear handle with a switch/speed control, a front handle and a drive unit for rotating the saw structure. The drive unit itself including a saw structure drive arrangement to which the saw structure is attachable, a transmission for driving the saw drive arrangement, an electric motor for driving an input shaft of the transmission, and a support structure for holding/carrying the saw structure drive arrangement, the transmission and the electric motor. The front handle and the rear handle are directly connected to each other to form a handle unit, which unit is resiliently connected to the drive unit, so that vibrations from the saw blade and drive unit will be reduced in the handle unit.
