According to the manufacturer, the Turbohead Xpro with SDS plus drive has established itself as one of the best hammer drill bits since its market launch four years ago. Its four-sided solid carbide cutting head is shaped in the form of an X and ensures a fast drilling progress even through reinforced concrete as well as producing exact drill holes. The Keil Werkzeugfabrik (Keil Tool Manufacturer) has now further developed the multi-cutter hammer drill bit for percussion drills. The Turbohead Xpro with round-section shaft can be inserted into any three-jaw chuck. Compared with other conventional concrete drill bits with round-section shafts, it is characterised by the fact that wear and tear is considerably reduced.www.keil.eu
