A power tool includes a resin member in a rotor that is less susceptible to breaking. A power tool includes a stator, a rotor rotatable relative to the stator at a speed of 30000 rpm or greater, and an output unit drivable by the rotor. The stator includes a stator core, an insulator fixed to the stator core, and a coil held on the insulator. The rotor includes a rotor core having a slot, a permanent magnet received in the slot in the rotor core, and a resin member fixing the rotor core and the permanent magnet. The resin member includes an annular portion protruding from an end face of the rotor core. The annular portion includes a cut portion.

A power tool includes a housing having a motor housing portion and a handle portion coupled thereto, an arbor supported by the housing, a working element attachable to the arbor for movement therewith, a motor positioned within the motor housing portion and configured to drive the arbor, a first lighting element positioned proximate an end of the handle portion, and a second lighting element positioned on the motor housing portion. The first lighting element is configured to illuminate a workpiece behind the working element and the second lighting element is configured to illuminate the workpiece in front of the working element.

A ring saw includes a ring saw blade, a tool holder that guides the ring saw blade in a cutting plane, a motor, and a driving wheel where the ring saw blade is drivable in the cutting plane by the driving wheel and the driving wheel is coupled to the motor. A guide roller is disposed on a first side of the cutting plane where the ring saw blade is guidable by the guide roller from the first side. A guide roll is disposed on a second side of the cutting plane where the ring saw blade is guidable by the guide roll from the second side. The guide roll is disposed in a hood that is pivotable relative to the cutting plane.

Plunge saws with cut indicators and methods of operating plunge saws are disclosed herein. The plunge saws include a motor and an arbor, which is configured to operatively attach a circular saw blade to the plunge saw and to receive a torque from the motor. The plunge saws also include a base plate and a base plate pivot. The plunge saws further include a plunge mechanism, which is configured to be selectively actuated, by a user of the plunge saw and during operative use of the plunge saw to cut a workpiece, to transition the plunge saw from a retracted orientation to a plunged orientation and to plunge the circular saw blade into the workpiece. The plunge saws also include a cut indicator, which is configured to project a light line onto the workpiece to visually indicate, on the workpiece, a location of an edge of the circular saw blade.

A table cutting device includes: a workbench on which a workpiece is capable of being placed; a cutting assembly capable of performing a cutting operation on the workpiece; a drive assembly including a motor and driving the cutting assembly to move; and a power supply connection assembly for connecting a battery pack. The battery pack supplies an energy source to the table cutting device. The table cutting device further includes a display assembly capable of displaying an electric quantity of the battery pack. When the battery pack is mounted to the table cutting device, the distance between the display assembly and the battery pack is greater than or equal to 5 mm. The table cutting device has the additional display assembly so that an operator can observe electric quantity information of the battery pack when operating the table cutting device, thereby greatly improving operation convenience.
