2024 Center Rock 96" & 120" DTH Hole Openers

These are brand new 8ft & 10ft DIA Hole Openers by Center Rock, Inc. Designed for medium to extreme hard rock drilling utilizing air percussion.

Hole Openers are designed to enable large diameter shaft drilling by utilizing the step-out installation method to keep air volume requirements at a minimum. These two units both require a lead shaft to be drilled 72" DIA so they follow the existing 6ft shaft down to depth enlarging to their respective diameters. These two come with cannister, hammers, bits, chucks and calyx baskets.

Both units were purchased NEW and never put to use - not a scratch.
