Excore Underground

For performance-driven companies, this piston latch head assembly features double seals in front of the latches. The secure latching and the mechanical piston that locks the head in the locking coupling is extremely strong, even in high back pressure holes. Along with primary landing indication, a secondary latching indication will let the driller know if the latches are not fully engaged; signalling that further actions are required.

The Excore Underground head uses a patented design to deliver improved durability and performance when compared to more standard head types available in the market.

Easy conversion to surface applications
