ESCO Helilok dredge points for rock dredging are designed with a trapezoidal bit cross section to maintain sharpness. Chisel and flared points are designed for sand and clay applications.
ESCO Helilok dredge points feature:
- Points that fit onto adapters with a quarter twist and butt fit against the adapter nose to directly take thrust loads
- A helical thread and large stabilizing flat that distributes loads over the entire adapter nose for exceptional strength
- A one-piece lock that provides positive point retention
