Grinding Tool
18 Jan 24
To reduce wasteful power consumption and noise generation, a control circuit drives a motor in response to a switch being turned on after a handle detector detects attachment of an auxiliary handle and a handle gripping detector detects gripping of the auxiliary handle, controls the motor to rotate at a predetermined first rotational speed in response to the switch being turned on with the attachment and the gripping of the auxiliary handle being detected, and controls the motor to rotate at a second rotational speed lower than the first rotational speed in response to a state of a load on a tip tool being unchanged for a predetermined period of time.
