High Performance Y19A Jack Hammer with 28-40J Impact Energy for Mining Applications

We've been shiping these Y19A units steady to the US and EU for about two years now, and most buyers go with the 10mg version for general quarry work. It basically runs at 0.4 to 0.5 Mpa working pressure, and the impact energy hits somewhere between 28 and 40J depending on the air supply — pretty typical for a hand-held pneumatic rock drill in this class. impact frequency is ≥28-35 Hz, which is fine for limestone and road construction, but we don't recommend it for very hard granite.

At 19kg and 600mm long, it's compact enough for one person to handle in tight spots, like small quarries or trench work. The cylinder diameter is 65mm with a 54mm piston stroke, and the shank size is H22*108 — that combo gives decent power transfer without being too heavy. Air consumption runs about 37 to 43 L/S, so you'll want a compressor that can keep up, usually with a 19mm inner diameter hose.

Compliance-wise, our company provide the ISO 9001:2008 certificate and a COA with every shipment, so customs in the UK or EU shouldn't be a headache. We've also got teh TDS and SDS ready if needed, and the warranty is one year form delivery. Lead time is typically 20 days or so, but we usually have stock — just confirm before ordering.

Drilling diameter is 34-40mm, and rotation speed is ≥180-200 r/min, which is good for most small-scale blasting holes. The 65mm bore and 54mm stroke mean consistent impact, but it's not meant for continuous heavy production — think more for repair work or small site drilling. We've seen buyers use it in road patching and limestone benches, and it holds up fine.

Anyway, if you're ordering for a US site, make sure the air coupling is compatible — we ship with standerd 19mm fittings, but you might need an adapter. The H22*108 shank is pretty common, but it's worth double-checking your drill steel before you place the order. We don't do custom packaging, but each unit comes in a sturdy cardboard box with basic foam padding.
