ABSTRACT:
A rock drill for drilling a plurality of arrayed continuous bores includes a plurality of rods positioned so as to be able to drill several arrayed continuous bores, a rotating member to give rotation to the rods and a single percussion member which imparts percussive force to the plurality of rods. The plurality of rods may be passed through integrally formed rod guides by connecting several cylindrical members juxtaposed in parallel. The guide rod may optionally include, at its rear end, a swivel which also acts as a rod holder.
