Cores through structural concrete. Rebar included.
The CrownForce CF-EC-77 is a rig-mounted wet core bit for the jobs that stop every other bit: cured structural concrete with rebar in it. The 3" (77mm) size cuts the hole for a 2" drain line, the most common core size in slab plumbing.
Built for rig work▼
- Rebar-rated laser-welded segments. Cuts through embedded rebar without stripping segments. Carbide and dry bits can't touch steel. This one goes through it.
- 15" (380mm) barrel. Cores thick slabs, footings, and foundation walls without stopping to clear.
- 1-1/4"-7 thread. Standard US core rig spindle. Mounts on Hilti, Husqvarna, BLUEROCK, VEVOR, and every common rig.
- Wet only. Water keeps the segments cool and flushes slurry for a fast, straight core.
