A handheld power tool 10 includes a detection signal acquisition unit 31, a determination unit 32, a display unit 24, a display control unit 34, a motor 14, and a drive control unit 13. The detection signal acquisition unit 31 acquires a detection signal that changes according to the detection strength of rebar W1 in concrete W. The determination unit 32 determines the presence or absence of the rebar W1 based on the acquisition result acquired by the detection signal acquisition unit 31. The display unit 24 displays the presence or absence of the rebar W1 by turning on different lights. The display control unit 34 controls so as to switch the color of the light displayed on the display unit 24 on the basis of the determination result by the determination unit 32. The motor 14 rotationally drives a tip tool 18a that works the concrete W. The drive control unit 13 controls the drive of the motor 14.

A metal detector 20 includes a cover 25, a detection signal acquisition unit 31, a determination unit 32, a display unit 24, and a display control unit 34. The cover 25 is removably attached to a tip portion 18 of a handheld power tool 10. The detection signal acquisition unit 31 acquires a detection signal that changes according to the detection strength of rebar W1 in concrete W. The determination unit 32 determines the presence or absence of the rebar W1 on the basis of the acquisition result acquired by the detection signal acquisition unit 31. The display unit 24 displays the presence or absence of the rebar W1 by lighting lamps in different colors. The display control unit 34 controls so as to switch the color of the light displayed on the display unit 24 on the basis of the determination result by the determination unit 32.

Illustrative embodiments of impact tools with impact mechanisms rigidly coupled to electric motors are disclosed. In at least one illustrative embodiment, an impact tool may comprise an impact mechanism, an electric motor, and a control circuit. The impact mechanism may comprise a hammer and an anvil, the hammer being configured to rotate about a first axis and to periodically impact the anvil to drive rotation of the anvil about the first axis. The electric motor may comprise a rotor that is rigidly coupled to the impact mechanism, the electric motor being configured to drive rotation of the hammer about the first axis, The control circuit may be configured to supply a current to the electric motor and to prevent the current from exceeding a threshold in response to the hammer impacting the anvil.

Control method for a dust extraction module (2) for a chiseling tool (5), including the following steps: using a fan (18) of the dust extraction module (2) to draw in an air flow Q from a certain place of a substrate (31) being worked by the tool (5), using a material detector (24) to identify the material M at the place of the substrate being worked by the tool (5), and adapting the suction power of the dust extraction module (2) as a function of the identified material M in order to set the air flow Q. The air flow Q is greater than or equal to a rated value Qo in the case of an iron-free mineral material M1, whereas the air flow Q is less than the rated value Qo in the case of a material M2 containing iron.

A power tool communication system including an external device including a first controller configured to transmit, via wireless communication to a power tool, configuration data including a work light duration parameter value and a work light brightness parameter value. The power tool includes a housing, a brushless direct current (DC) motor, a trigger, a work light, a wireless communication circuit configured to wirelessly communicate with the external device to receive the configuration data, and a second controller configured to control a work light duration of the work light based on the work light duration parameter value, and control a work light brightness of the work light based on the work light brightness parameter value.

A pavement breaker has a housing, a hammer mechanism mounted within the housing, and at least one handle moveably mounted on the housing. The handle(s) can move in a vertical direction when the pavement breaker is orientated in its normal operation orientation. A sensor is mounted within the housing for detecting when the handle(s) is moved towards or at its uppermost position. If the sensor detects such handle position, the hammer mechanism is deactivated.

A programmable power tool and method and systems of programming a power tool using wireless communication. An external device having a processor and a transceiver establishes a communication link with the power tool. The external device receives, with the transceiver, a first mode profile stored on the power tool. The first mode profile is defined by a profile type and a first value associated with a parameter for executing the profile type. The external device displays a control screen including the profile type and the parameter at the first value, and receives a user input. The external device generates, in response to the user input, a second mode profile by modifying the parameter to be at a second value. The external device transmits, with the transceiver, the second mode profile to the power tool.

Provided is an electric tool with which work efficiency can be improved. A controller of an electric tool can execute: a first control, whereby during a non-operating state after a motor has started up and before a tip tool is set to be in an operating state, the motor is driven at a slow idling rotation speed, and when the tip tool is set to be in the operating state, the motor is driven at a normal rotation speed which is higher than the slow idling rotation speed; and a second control, whereby in a case where a trigger switch has been turned off in a state where the motor is being driven at the normal rotation speed and the trigger switch is thereafter turned on again under a prescribed condition, the motor is driven at the normal rotation speed regardless of the state of the tip tool.
