A power tool including a housing, a motor having a rotor and a stator, at least one grip sensor configured to generate a grip parameter, and a switching network electrically coupled to the brushless DC motor. An electronic processor is connected to the switching network and the at least one grip sensor and configured to implement kickback control of the power tool. The electronic processor is configured to determine a kickback threshold based on the grip parameter, control the switching network to drive the motor, receive a signal related to a power tool characteristic, determine, based on the power tool characteristic being greater than or equal to the kickback threshold, that a kickback event of the power tool is occurring, and control, in response to determining that the kickback event is occurring, the switching network to cease driving of the motor.

Kickback control methods for a power tool including a force sensor

A cut-off saw configured to remove material from a workpiece, the cut-off saw includes a motor, a blade, a drive assembly, a handle, and a coating. The blade is capable of removing material from the workpiece upon contact between the blade and the workpiece. The drive assembly is coupled to the motor and the blade and is configured to transmit torque from the motor to the blade. The handle is configured to be grasped by a user, and includes a surface and a first material having a first surface resistivity. The coating covers at least a portion of the handle. The coating is configured to distribute static electricity away from the surface. The coating is made of a second material having a second surface resistivity less than the first surface resistivity.
