ZT44 Blasthole Drills

The ZT44 is a down-the-hole surface drill rig designed for mining-duty applications. It offers high reliability and production with purpose-built structures, a high horsepower engine and large capacity dual-setting compressor that adapts to varying rock hardness conditions. The ZT44 is a versatile machine, used for pre-split, production, auxiliary and other demanding needs.

ZT44 Blasthole Drills

Dual-pressure air compressor

With both high- and low-pressure drill settings, this compressor can adjust to changing drilling conditions, allowing for optimal performance up to 8.5-inch hammer. This largest compressor in its class can handle challenging elevations where production often drops off.

High tractive force and more

Powerful tractive force and an independent oscillating undercarriage deliver maneuverability on uneven grades and the ability to perform in various settings. That gives your operation more flexibility to determine the optimal use of your machine.

Compact design

The ZT44 blasthole drill adds exceptional versatility to your operation with a compact form that is designed for efficient drilling in tight spaces, while still providing the production capacity of larger machines.
