5, electric impact drill: this method is suitable for compacting concrete and drilled hard masonry materials, high speed, high precision, drilling up to 29 mm in diameter.

6, pneumatic impact drill: this is the fastest method, but drilling cannot always meet the requirements of accuracy and shape. This is a way for heavy civil construction drilling large diameter holes.
