If you’re shopping for a jack hammer that’s built for real demolition work (not light chipping), the G16 Pneumatic Air Pick Hammer is the kind of tool that immediately makes sense once you look at the numbers. It’s a hand held jack hammer, but it’s clearly designed for heavy materials—thick concrete, hard pavement, compact surfaces, and industrial breaking jobs where power and stability matter more than “lightweight comfort.”
The G16 keeps a practical overall length of 580mm, runs at a steady 0.63Mpa working pressure, and delivers a strong 55J impact energy through a long 155mm hammer stroke. It’s also a heavier 15KG Pneumatic jack hammer, which sounds intimidating at first, but in real use that weight can actually help the tool stay planted and break faster with less bouncing.
G16 Pneumatic Jack Hammer Specs (and What They Mean in Real Use)
Here are the core specs of the G16 Pneumatic Air Pick Hammer, with some straight talk on why they matter:
Machine length: 580mm
A good working length for control and leverage. It’s long enough to feel stable, but not awkward to handle.Piston diameter: 40mm
This is one of the highlights. A 40mm piston means more driving force behind each strike, which is exactly what you want when material is hard and dense.Hammer stroke: 155mm
The 155mm stroke helps the tool hit “deeper” rather than just rattling the surface. It’s a big part of why the G16 feels aggressive on concrete.Impact energy: 55J
55J is serious power for a hand held unit. It’s the kind of impact energy that helps you crack slabs faster and reduce time spent fighting the same spot.Impact frequency: 16Hz
At 16Hz, the G16 isn’t trying to win with speed alone—it’s more about controlled, heavy hits. That’s often better for thick materials where shallow rapid blows don’t help much.Air hose inner diameter: 19mm
The tool is designed around a 19mm hose for airflow. If the hose is smaller, you’ll feel the tool weaken under load.Air consumption: 28L/s
The G16 needs 28L/s, so it’s not meant for tiny compressors. Give it proper airflow and it performs the way it should.Working pressure: 0.63Mpa
Runs at 0.63Mpa, a common working pressure for heavy pneumatic tools, and stable enough for long work sessions.Chisel shank size: 24×70mm
The 24×70mm shank size is a solid heavy-duty standard—good for matching the impact level without loose fit issues.Total weight: 15KG
This is a 15KG Pneumatic jack hammer, which puts it firmly in the heavy-duty category. It’s not “light,” but it’s stable, and stability is what breaks concrete faster.
Where the G16 Hand Held Jack Hammer Works Best
From the spec combination (55J, 155mm stroke, 40mm piston, 15KG body), the G16 is a great fit for:
Concrete slab demolition (thicker floors, foundations)
Road and pavement breaking work
Industrial repair and maintenance jobs
Heavy site work where stability matters more than portability
Any project where smaller jack hammers start feeling underpowered
If your main job is “break and remove,” this jack hammer is built for it.
Customer Questions (Answered Like a Real Buyer Would Ask)
1) Is the G16 too heavy to be a hand held jack hammer?
It depends on the job. At 15KG, it’s not something you want to hold overhead all day.
But for ground work—breaking pavement, concrete floors, road surfaces—the weight actually helps. A heavier hand held jack hammer tends to stay down, bounce less, and transfer more energy into the material instead of back into your arms.
2) Why choose G16 if it’s 55J but only 16Hz?
Because not every job needs maximum speed. The G16 delivers 55J impact energy at 16Hz, which usually feels like “slower but heavier” hits.
That’s often better for thick concrete where fast light impacts don’t bite deep enough. It’s a more controlled demolition style.
3) What air setup do I need for this Pneumatic jack hammer?
To get full performance, you should match the tool requirements:
Working pressure: 0.63Mpa
Air consumption: 28L/s
Air hose inner diameter: 19mm
The 19mm hose matters more than people expect. If airflow is restricted, the tool won’t hit like a 55J unit anymore.
4) Does the 40mm piston really make a difference?
Yes. The 40mm piston diameter helps deliver strong driving force per cycle.
Combined with the 155mm stroke, it’s one of the reasons the G16 feels like a “real breaker,” not just a surface chipping tool.
5) How do I keep the G16 running strong over time?
From practical jobsite experience, pneumatic tools stay healthy with simple habits:
Add pneumatic oil before starting work
Oil again every 2 hours during continuous operation
Keep the air line clean and dry
Use the correct 24×70mm chisel shank
Avoid running the tool without load (dry striking)
A strong Pneumatic jack hammer like this depends on lubrication and clean air. That’s where long service life comes from.
Final Summary: Who the G16 Pneumatic Air Pick Hammer Is For
The G16 Pneumatic Air Pick Hammer is a heavy, powerful jack hammer designed for demanding demolition work. With 55J impact energy, a long 155mm stroke, a strong 40mm piston, and a stable 15KG body, it’s built to break hard material efficiently—not just make noise.
If you want a hand held jack hammer that feels planted, hits deep, and performs best with proper airflow (0.63Mpa, 28L/s, 19mm hose), the G16 is a solid choice for construction and industrial breaking jobs.
