There is provided a handheld circular saw comprising a main body. The main body comprises a fixed blade guard configured to receive a circular cutting blade having an axis of rotation. A graspable handle is arranged in a forward position on the main body to enable a user to wield the power tool in use and a movable blade guard is arranged to surround at least a part of the cutting blade. An actuator arrangement configured to move the movable blade guard from a first position to a second position, where a greater proportion of the cutting blade is exposed in the second position than in the first position, the actuator arrangement having an actuator grip to enable the user to activate the actuator arrangement. The actuator grip is located and arranged forwardly of the graspable handle to enable actuation by the fingers of the user's hand which is grasping the graspable handle in use.

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 power tool with a rotatable tool designed as a saw blade or a milling cutter. The power tool includes a sensor device for detecting a mechanical quantity, the mechanical quantity including a force, an acceleration, a velocity, a deflection, a deformation and/or a mechanical stress. The mechanical quantity is dependent on a force emanating from the tool, and a control device communicatively coupled to the sensor device. The control device is adapted to recognize a kickback event based on the detected mechanical quantity, in which the control device is adapted to selectively determine a first recognition function or a second recognition function different from the first recognition function based on a function determination information, and to perform the recognition of the kickback event based on the detected mechanical quantity using the determined recognition function.

A portable cutting device having a cutting tool for cutting a material. The cutting device includes a motor driving the cutting tool and a shroud at least partially enclosing the cutting tool. The shroud defines a debris accumulation chamber for gathering debris created by the cutting tool cutting the material. An impeller is operatively coupled to the motor and driven by the motor to create suction pressure to draw the debris out of the debris accumulation chamber and into a collection bag.

Blade guard (20) configured to partially cover a rear face of a circular saw blade (9) while leaving a front face (9b) of the saw blade uncovered. The blade guard comprises: a guard plate (21) having an inner face (21a) configured to face the saw blade (9); and an elongated shielding unit (50) fixed to the guard plate (21) and configured to cover a part of the peripheral edge (14) of the saw blade.

The shielding unit comprises several shielding elements (52) arranged side by side along the shielding unit, each shielding element comprising a shielding member (53) and a resilient cantilever support member (54), wherein the shielding members are arranged side by side in a row in order to form an elongated barrier (55) capable of stopping cutting debris. The support members (54) allow the shielding members (53) to move in relation to each other and in relation to the guard plate (21).

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.
