Secure temporary anchoring for diamond drills

Practical benefits
  • Reusable Fischer spindle bolt: You quickly detach the durable spindle bolt after drilling and reuse it on your next job with a fresh expansion element.
  • High shear load capacity: The large steel cross-section withstands intense lateral forces and sudden jolts if the core drill bit binds unexpectedly.
  • Active controlled expansion mechanism: The expansion clip anchors firmly against the borehole wall to keep your heavy drilling rig perfectly stable.

In a nutshell

The right choise for

With the Fischer fdbb 16/50 set, you secure diamond core drills, drill stands, and diamond saws firmly into concrete and natural stone. The large steel cross-section provides high shear load capacity, easily absorbing heavy jolts if the drill bit binds unexpectedly during drilling. Thanks to the active expansion mechanism in a 16 mm borehole, your drilling rig stays completely stable and secure. Once your work is done, you easily dismantle the spindle bolt via the detachable screw connection. Only the expansion element remains in the drill hole, allowing you to quickly reuse the robust spindle bolt on your next job.
