Power tool blade type detection and automatic speed adjustment

A method for controlling operation of a power tool, the method comprising:

• receiving an accessory by an output driver of the power tool, the output driver coupled to a motor of the power tool, wherein the accessory is driven by the motor;
• detecting, by an accessory-type detector, a characteristic of the accessory;
• determining, by a controller, an operational characteristic for the accessory based on the characteristic of the accessory;
• and
• controlling, by the controller, operation of the motor according to the operational characteristic;
• wherein the accessory-type detector includes a magnetic sensor, and
• wherein the accessory includes a magnet that impinges the magnetic sensor such that the magnetic sensor detects a magnetic field.
