Slow Starting Function
Slow speed at the beginning of boring will securely set a hole cutting position.
Two speed electric drill with speed adjustment
Optimum drill speed adjustment can be made to bore a hole on difficult-to-cut materials or to securely set a hole cutting position at the initial cutting stage.
Load Indication and LED Condition
Load Indication
The load indicator (LED) indicates the condition of the load with different colors of LED light.
The LED lights up in green. → The load on the drill motor is normal.
The LED lights up in red. → The load on the drill motor is close to overload.
The LED blinks in red. →The drill motor is overloaded.
Automatic Stop Function
As the drilling load increases, the load indicator will change in color from green to red. In addition, if excessive feeding force is applied, the load indicator will rapidly blink red and the rotation of the drill motor will slow down and stop. After the drill motor has come to a complete stop, the load indicator will slowly blink in green. To resume the rotation of the drill motor, release the load and turn off the switch of the drill motor, and then turn it on.
Automatic Restart Function
If the load is released while the load indicator is blinking red, the drill motor will resume its rotation.
Built-in Motion Sensor
If any lateral movement or excess vibration is detected during drilling a hole, the drill motor stops instantly and the LED blinks red. To resume operation, turn the magnet switch off and on.
Fail-safe Restart
The magnetic field will become active, but the drill will not re-start even if power is re-supplied after accidental shutdown. The LED will blink green at this stage. Drilling can only be continued after turning on the drill switch.
Magnet Open-circuit Sensor
The drill will not start until the magnetic field is active. If a malfunction occurs on the magnet, the LED will blink red slowly and the drill motor will not revolve.
Features
