It also has advanced features such as Electronic Precision Control, for smoother bit starts; Vibration Control, for extended user comfort; and Electronic Motor and Cell Protection, to avoid overheating and overload. It has an ergonomic L-shaped design for easier horizontal drilling. Includes: (1) GBH18V-26 18-Volt Rotary Hammer, (1) Auxiliary Handle, (1) Depth Gauge.
