The special FZUB drill enables a fast installation by creating the undercut drill hole (undercut) without a tool change. Suitable for undercut anchors FZA, FZA-I, FZA-D, and FZEA II.
Once the anchor has been placed into the drill hole, the expansion sleeve of the undercut anchor is driven over the cone using the setting tool FZE Plus, and the undercut drill hole is filled with a positive fit.
