Medium-pressure Down-the-hole Impactor
Avoid the "high fuel, low progress" trap If you've ever worked a site where the rock is too hard for low-pressure tools, you know the frustration. You end up burning fuel while the drill barely scratches the surface. Our Medium-pressure down-the-hole impactor is designed specifically for that middle ground—hard enough to handle granite or basalt without forcing your air compressor to run at its absolute limit.
The real-world benefits (No fluff)
Solid penetration, less "bouncing"
We've matched the piston weight perfectly to the drill bit. When it strikes, the energy goes straight into the rock. You'll notice it doesn't vibrate uncontrollably or "dance" on the rock face; it just digs in and stays steady.
Simple internal design means fewer headaches
This is a valveless model. On a dusty site, complex valves are usually the first thing to fail or jam. By keeping the internals simple, we've cut down the parts that can break, making it much easier to clean and maintain in the field.
Thicker walls for a longer life
We use high-grade alloy steel that's been properly heat-treated. If you compare it to cheaper alternatives, you'll feel the weight difference. That extra thickness in the outer cylinder means it won't wear thin after a few weeks of abrasive drilling.
Clears dust fast
The internal air channels are wide enough to flush out cuttings efficiently. This keeps the bottom of the hole clean and, more importantly, prevents the bit from getting stuck in its own dust.
Choosing the right model
BR1 / BR2 / BR3: These are our "workhorses" for blasting holes and water wells. They cover hole diameters from 64mm to 110mm.
M2: If you're working in particularly dusty conditions or deep holes where flushing is a struggle, the M2 has a slightly more aggressive air blast to keep the hole clear.

A few honest tips from our technical team
Don't skip the oil
Most Medium-pressure down-the-hole impactor failures we see are due to dry friction. Spending a few dollars on rock drill oil for your lubricator will save you thousands in replacement parts.
Watch your pressure
Keep it between 0.7 and 1.5 MPa. Pushing it too high won't necessarily make it faster, but it will definitely wear out your internal seals prematurely.
One small downside
It's a bit heavy to haul around. But honestly, if a tool in this industry is too light, it usually means the manufacturer cut corners on the steel. You want that weight for stability when you're hitting hard rock.
Reliable check valve
We've built in a high-quality check valve. If you hit a water table and shut off the air, mud and water stay out of the internal mechanism. It's a small detail that saves a lot of cleaning time.
Who is this for?
If you run a quarry, a foundation piling crew, or a water well business and you're tired of stopping work to fix "budget" tools, this Medium-pressure down-the-hole impactor is the right fit. It's built for heavy lifting and won't let you down when the terrain gets tough.
