A power tool includes a housing. A motor is housed in the housing. A platen is driven by the motor. The housing includes a first housing part, a second housing part and a third housing part. The housing defines a battery receptacle portion configured to receive a removable battery pack which powers the motor. Each of the first housing part, the second housing part and the third housing part form part of the battery receptacle portion.

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.

A power tool system includes a removable battery pack a first tool and a second tool. The first tool includes a first base housing that is selectively engageable with the removable battery pack and a first tool portion connected to the first base housing by a first connecting section. The second tool includes a second base housing that is selectively engageable with the removable battery pack and a second tool portion connected to the second base housing by a second connecting section. The second tool base housing houses a second controller that provides a proportional power delivery system for the second tool and second tool base housing also includes a second actuator for providing user control of the second tool.

Disclosed is an angle grinder. An operation body is configured to control the polishing of an action head end, one end of a head housing is detachably connected to the operation body, the other end of the head housing is detachably connected to a front cover. One end of a rotor shaft extends out of the head housing and the front cover; a bearing is sleeved on the periphery of the rotor shaft; the front cover is located on the periphery of the bearing; and an installation stopper can be detachably installed on the rotor shaft and can rotate synchronously with the rotor shaft. One side of the bearing is in contact with the shoulder of the rotor shaft, and the other side of the bearing is contact with the installation stopper. The bearing can be clamped by the installation stopper and the shoulder of the rotor shaft.

A tool system includes an image capturing unit, a storage unit, a class identifier, and a spot determiner. The image capturing unit shoots a work spot of a target article and thereby generates captured image data. The storage unit stores a plurality of reference image data items with the plurality of reference image data items classified into multiple groups according to respective classes of the plurality of articles. The class identifier acquires identification information to identify the class of the target article. The spot determiner determines the work spot shot by the image capturing unit by comparing the captured image data with one of the plurality of reference image data items, which belongs to one of the multiple groups that is associated with the class of the target article identified by reference to the identification information.

A portable power tool includes an electromotive drive with an output shaft defining a first axis and having a first end portion and a second opposite end portion. The first end portion is between a mounted machining tool and the second end portion. The electromotive drive is received in a first power tool housing portion and includes a stator having a first stator end defining a first plane and a second stator end defining a second plane, the first plane is located between the first end portion and the second plane. A second power tool housing portion defines a handle gripping portion with a first surface defining a third plane which intersects the output shaft at a location whereat the first plane is between the third plane and the second plane. A second surface portion opposite the first surface portion defines a fourth plane parallel to the third plane.
