A train is moving on rails like lightning. You can drill just as fast with our TCT core drills especially made for railway tracks. What makes our core drills unique: high concentricity, immediate centering, no 'running' of the drill hole and fast core removal by means of an ejector pin - and all this with very low energy consumption. A further plus point is the Alfra chip breaker system: A three-stage gate with pre-, middle- and re-cutter is dividing the chips and prevents them from jamming. These models of the ALfra series of carbide reinforced core drills are fitting on all portable magnetic drills with 19 mm Weldon shank and especially on rail drilling machines of the brands Cembre, Erico, KKT, Dubuis, Universal, Magtron and Rotabroach.
