We moderate reviews before they're published, but we don't fact-check them
Reviews are written by equipment owners and operators. Our team looks over each review before it goes live, and anyone can report a review they think breaks the rules.
We don't verify the claims made in reviews, so each one reflects the reviewer's own experience. Some reviews may have been collected from other public sources. Brands can reply to reviews but can't edit or remove them.

Consistent output, good pace
Posted on Aug, 12 2026
We've been running the ZR122 for six months. It maintains a strong pace, drilling consistent 13 3/4 inch blastholes. I'm still exploring its full capabilities, but the daily output is solid.

Intuitive controls, fast training
Posted on Aug, 12 2026
Our previous drill made training new operators a headache. The ZR122's controls are so intuitive; new hires are productive on 13 3/4 inch holes in days. It's a smooth operation daily.

Simple to operate, good output
Posted on Aug, 12 2026
This Komatsu 320XPC is surprisingly intuitive. Operators pick up the controls quickly, even new hires. Drilling 12-inch holes all day is less fatiguing than on older rigs.

Reliable drilling, decent support
Posted on Aug, 12 2026
After 18 months, this drill consistently hits our 17-inch targets. Parts availability is solid, though a few times we waited longer than ideal.
