ESCO Vibration drill for concrete (long)

Please use with a vibration drill (vibration mode) dedicated to long size vibration. It cannot be used for impact drills and drill drivers. Drilling close to a perfect circle is possible. Positioning performance is improved. Deck plates in which concrete is placed in the drilling of mortar blocks with a vibration drill can be easily drilled with less catching and impact, and stable drilling. Less burden on the body even when used for a long time, reducing fatigue, less catching when contacting the reinforcing bars, and reducing swinging by the motor. Improved safety
