MASTER OF VERSATILITY
Expectations are high and innovation is an obligation at the very top. It is a claim we take very seriously.
The new ALPEN Sprint Master will show you new dimensions of speed and reliability. It reduces drilling time by around a third thanks to optimized drill geometry and the special ALPEN tip shape. And still delivers the customary top-quality result.
Satisfaction is guaranteed further still by a longer service life that has been increased by a factor of 3 through the use of high-quality HSS steel and a special heat treatment process. The speed and long-term efficiency of a champion are words that best sum up our ALPEN Sprint Master.
