The most successful Heller hammer drill bit of all time! The Bionic Pro
SDS-plus dual cutter is extremely robust and very powerful. The patented
carbide drill tip guarantees a long service life and, in combination with the
optimized carbide cutting edge, ensures especially fast drilling. Another
advantage is the Twinmax 3D helix, which very effectively transports drilling
dust away, and thus minimizes the risk of dust 'blow back'
