Curtain up for the heavy metal experts among the Alfra core drills. With materials such as construction steels, chrome-nickel steels and non-ferrous metals such as aluminum or CuZn alloys, they are running up to top form. What makes them unique: high concentricity, immediate centering, no 'running' of the drill hole and the fast core removal by means of an ejector pin - and all this at a very low energy consumption. The special chip flute shape prevents jamming, while the Alfra chip breaker system is ensuring 'nice chips' in three steps. Our experts fit all machines with Weldon shank, ALFRA-Rotabest, Alfra-Rotaquick quick change system, BDS, Bux, Ruko, Magnetor, Euroboor, Universal, Jancy, Hougen, Magtron, Promac, Rotabroach and others.
