DESCRIPTION<\/div>[vc_column_text]Core bits for dry drilling with dust extraction system. This model, as well as all the others in the dry range, was developed for drilling reinforced concrete without water. For mounting on manual core drills, the rotating head is required (see accessories page). The useful drilling length is 300 mm, the total length, including the attachment, is 370 mm. If necessary, it can be used with water on core drills with direct 1 \u201d1\/4 male connection.[\/vc_column_text]
