Engineered for high productivity drilling in tough rock conditions, the ZR122 drill is built to help reduce maintenance costs, support fully autonomous operation, and can be configured for rotary and hammer drilling, diesel or electric power, and single- or multi-pass drilling.

As part of the ongoing process to integrate its legacy brands into One Komatsu, the newest drill model and technology was showcased on the Komatsu ZR122 with the new look and branding at the booth.

Designed to increase drilling time, the rack-and-pinion pulldown system reduces the maintenance time required to support the old cable or chain pulldown and the boxer style mast reduces downtime for structural inspections.

To help reduce bit change downtime and worker risk associated with a manual changeout process, an advanced auto-bit changer carousel helps to flex into a new hole diameter rapidly so operators can seamlessly adapt the drill pattern to reach peak fragmentation quickly. The one-touch, auto-bit operation keeps productivity going with a five-minute change.

Customers can elevate their mine's productivity by improving drilling accuracy with high-precision GPS through auto-navigation capabilities, allowing line-of-sight tele-remote operations from up to one mile away.
