A handheld working tool for treating a workpiece comprises a tool nose provided for contacting the workpiece at a working point, and an indicator provided for indicating a reference point on a surface of the workpiece at a predetermined distance to the working point when the tool nose contacts the workpiece at the working point.

Circular saws with transparent windows that extend within blade guard openings and cover fastening structures. The circular saws include a motor and an arbor configured to operatively attach a circular saw blade to the circular saw. The circular saws also include a blade guard. The blade guard includes a blade guard opening, which is positioned to permit a user of the circular saw to view a leading edge of the circular saw blade as the circular saw cuts a workpiece. The circular saws also include a transparent window, which extends within the blade guard opening, and a cover fastening structure, which is configured to selectively attach a splinter guard to the blade guard while the transparent window extends within the blade guard opening.

Track saws with self-adjusting rib-guide assemblies and methods of operating self-adjusting rib-guide assemblies of track saws are disclosed herein. The track saws include a motor, an arbor, and a base plate. The base plate defines an arbor-facing side and an arbor-opposed side. The base plate includes a rib-receiving channel and a self-adjusting rib-guide assembly. The self-adjusting rib-guide assembly at least partially defines the rib-receiving channel and is configured to automatically accommodate a range of raised rib transverse widths. The methods include positioning a raised elongate rib of the track within a rib-receiving channel of a base plate of the track saw. During the positioning, the methods also include establishing a contact force between the raised elongate rib and the self-adjusting rib-guide assembly. Responsive to the contact force, the methods further include moving at least a portion of the self-adjusting rib-guide assembly relative to a remainder of the track saw.

A reciprocating saw includes a casing, a clamping mechanism, a bracket, a first light-emitting piece, and a second light-emitting piece. The casing extends in a front-and-rear direction and forms an accommodation space. The clamping mechanism is disposed at least partially in the accommodation space and configured to clamp an operation accessory. The bracket is disposed at least partially on a front side of the clamping mechanism. The first light-emitting piece and the second light-emitting piece are disposed on a front side of the casing. The first light-emitting piece fits with the bracket and the operation accessory so that a cutting indicator line distributed in an extension direction of the operation accessory is formed. The second light-emitting piece fits with the bracket so that a cutting indicator region perpendicular to the cutting indicator line and extending in an up-and-down direction is formed.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a saw blade and a lower blade guard covering a lower portion of the saw blade. The miter saw also includes a linkage for raising the lower blade guard to expose the lower portion of the saw blade as the saw unit is lowered toward the base assembly. The linkage is operable to apply a force to the lower blade guard for holding the lower blade guard in a raised position, without any input from the operator of the miter saw and without changing the length of the linkage, to facilitate changing the saw blade.

A cutting length display device for a hand-held machine tool includes at least one display unit that has at least one light source. The display unit is configured to display at least one position of a cutting edge of a machine tool on a workpiece to be machined depending on a set cutting depth of the machine tool by way of a light beam. The display unit has a mirror unit that is configured to deflect the light beam depending on the set cutting depth of the machining tool.

A method of machining at least one concrete part includes providing at least one concrete part; applying at least one marking to the at least one concrete part; arranging at least one machining device for machining the at least one concrete part relative to the at least one concrete part; detecting the at least one marking by at least one marking detection device and transmitting the marking data thus generated to the at least one machining device; and machining the at least one concrete part using the generated marking data by the at least one machining device.

Disclosed is a portable automatic panel cutter (1) comprising one or more remote operator interfaces (2) adapted to receive instructions from an operator regarding dimensional processing of a panel (3) in the portable automatic panel cutter (1). The portable automatic panel cutter (1) is adapted to automatically cutting the panel (3) into two or more panel parts (4) according to the instructions. Furthermore, the portable automatic panel cutter (1) also comprises an automated marker tool (5) configured for marking at least one of the two or more panel parts (4) with one or more identification marks (6) in response to the instructions. A method for marking one or more panel parts in a portable automatic panel cutter (1) and use of a portable automatic panel cutter (1) is also disclosed.

A method of indicating processing steps to be carried out on a workpiece mounted in processing machine, the method comprising a step of visualizing at the same time or sequentially a succession of individual planned processing steps to be applied to the workpiece, prior to execution of said processing steps and a processing machine comprising a processing unit, a moving table and a controller.

A circular includes a housing, a sawing assembly including a motor and a saw blade located at two opposite sides of the housing and connected together so that the saw blasé can be driven by the motor to saw the workpiece and a saw blade shield secured to the housing and covering a part of the saw blade to prevent the saw blade from cutting the surrounding people, and a prism assembly including a protective cover affixed to the front end of the saw blade shield and a prism located in the protective cover to reflect the image of the saw blade sawing the workpiece through a window of the protective cover to the line of sight of the operator. In this way, the operator can clearly confirm whether the sawing path is skewed with the normal operating posture to improve the efficiency.
