1. Triple anti-leakage and green design of the machine body, double insulation design of the motor and patented insulation rubber sleeve design of the feed rod.

Designed to prevent leakage caused by drilling into wires or power sources.

2. Automatic trip switch for motor overload: During drilling, if the current exceeds the rated current of the motor load, the motor will automatically cut off the power.

3. Built-in externally adjustable clutch: If the drill bit is stuck in the hole, the clutch of the machine will automatically trip to protect the internal gears of the gearbox.
