Power tool

A power tool comprising:

• a motor;
• a tool accessory-retaining part configured to be driven by the motor;
• a controller configured to control the motor according to at least first and second motor rotational speeds that are manually selectable and at least first and second driving modes that are manually selectable, the at least first and second driving modes differing in a sequence of motor rotational speeds during a fastening operation;
• and
• a display comprising at least first and second LEDs connected to the controller, a motor speed change switch connected to the controller and a driving mode change switch connected to the controller,
• wherein the controller is configured to:
• select the rotational speed of the motor from among the at least first and second motor rotational speeds in accordance with manual operation of the motor speed change switch and to visually indicate the selected rotational speed of the motor by illuminating at least one of the at least first and second LEDs;
• and
• select the driving mode of the motor from among the at least first and second driving modes in accordance with manual operation of the driving mode change switch and to visually indicate the selected driving mode of the motor by illuminating at least one of the at least first and second LEDs.

An impact tool comprising:

• a brushless motor;
• a hammer configured to be driven by the brushless motor;
• an anvil configured to receive rotary impacts from the hammer;
• a hammer case housing the hammer;
• a main housing that accommodates the motor;
• a handle extending from the main housing;
• a power-supply unit disposed at a terminal end of the housing;
• a battery pack detachably attached to the power-supply unit;
• and
• a display disposed on the power-supply unit;
• wherein the display includes a plurality of LEDs configured to selectively visually indicate both a plurality of selectable motor rotational speeds and a plurality of selectable driving modes.

A power tool comprising:

• a main body housing that accommodates a motor;
• a handle extending from the main body housing;
• a power-supply unit disposed at a terminal end of the handle and configured to detachably attach a battery pack;
• a controller disposed within the power-supply unit and including a motor control circuit board configured to control the motor;
• a display provided on the power supply part and configured to visually indicate a selected operating state of the motor controlled by the controller;
• wherein the display includes:
• a first switch;
• a second switch;
• a first light disposed adjacent to the first switch and configured to be turned ON/OFF by manual operation of the first switch;
• a second light disposed adjacent to the second switch and configured to be turned ON/OFF by manual operation the second switch;
• and
• a plurality of third lights disposed side by side and between the first switch and the second switch;
• wherein the controller is configured to illuminate the first light when the first switch is manually operated while illuminating at least one of the plurality of third lights in accordance with a first operation mode selected from a first set of operation modes of the power tool that was manually selected via the first switch;
• and
• wherein the controller is configured to illuminate the second light when the second switch is manually operated while illuminating at least one of the plurality of third lights in accordance with a second operation mode selected from a second set of operation modes of the power tool that was manually selected via the second switch, the first set of operation modes differing from the second set of operation modes.
