The 4" core for drain lines through structural concrete.
The CrownForce CF-EC-102 is a rig-mounted wet core bit sized for the hole a 3" drain pipe needs. Cured concrete, rebar, footings. The stuff that kills lesser bits.
Built for rig work▼
- Rebar-rated laser-welded segments. Cuts through embedded rebar without stripping segments. When you hit steel mid-core, you keep going.
- 15" (380mm) barrel. Matches the deepest barrels on the market. Cores thick slabs and foundation walls in one setup.
- 1-1/4"-7 thread. Standard US core rig spindle. Mounts on Hilti, Husqvarna, BLUEROCK, VEVOR, and every common rig.
- Wet only. Water cooling keeps segments alive and cores straight.
