Heavy-Duty Kaishan Pneumatic Hammer for Mining and Water Conservancy Construction Works

Basically, what the Y018 does is handle heavy lifting on rock drilling in places like quarries or water conservancy sites—we've seen it punch through granite and limestone without bogging down, and the impact frequency holds steady at 32Hz or higher, which is pretty much what you need for consistent blast hole work at depths up to 9 meters.

On the spec side, it's 18kg and 550mm long, so it's not a lightweight toy, but teh 58mm cylinder diameter gives it that punch—impact energy's around 22J or more at 0.63MPa—and we've tested it with drag bits for rotary drilling at 300RPM no-load, though actual drill hole diameter runs 32mm to 60mm depending on the rock type.

Every unit we ship comes with a video outgoing-inspection—I mean, we actually record the test run and send it to you, so you see it cycle through pressrue ranges form 0.4MPa to 0.63MPa before it leaves the floor, and the batch consistency is tight because we check COAs batch-wise, not just random samples.

Anyway, we'll include the machinery test report with the order, and if you want to retest on arrival, just let us know—we usually have stock, but confirm lead time (roughly 20 days or so) because the MOQ is 5 units for the standdard warranty period of one year.

It's better than most pneumatic hammers for this kind of work—not suited for light-duty chipping or concrete breaking, honestly, but for drilling blasting holes in hard rock, it's what we recommend to contractors who need reliability over speed, and the 0.4-0.63MPa air consumption range means you don't need a massive compressor setup.

You'll get it in a standard plywood crate with the bit set included, and we've had buyers use it for railway construction too—just keep in mind the drag bit design works best in rotary mode, so don't try hammering with it, or you'll wear the cylinder faster than expected.
