Heller 16661 4 Bionic-Pro SDS+ 15mm x 450mm Drill Bit

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 optimised carbide cutting edge, ensures especially fast drilling. Another advantage is the Twinmax 3D helix, which very effectively transports drilling dust away, and thus minimises the risk of dust 'blow back'.

• Dual-cutter for concrete and reinforcement steel
• Extremely robust with long service life thanks to the patented drill head
• With recessed carbide tip for extreme resilience in reinforcement steel and powerful drilling progress
• Best drilling process thanks to the optimised carbide cutting edge
• Twinmax 3D helix for highly effective drilling dust transport and minimal dust inflagration even in deep holes
• Low vibration reduces the load on the user
• Particularly easy positioning and avoids spalling even after drilling many holes thanks to double centring tip
