Demolition Breaker 38mm Petrol Jack Hammer 52cc 2.4hp

A petrol demolition breaker built for heavy breaking and chipping work where mains power is not practical. With a 52cc 2.4hp 2-stroke engine and 38mm fitting, this jack hammer is suited to demanding site, groundwork and outdoor demolition jobs.

Used for breaking up concrete, brick, block and slabs, it is a practical option for trenching, foundation removal, hole breaking and general demolition work. Useful on jobs where you need to move around freely without trailing cables, it suits builders, groundworkers, contractors and serious DIY users tackling outdoor renovation or site clearance work. The supplied flat and pointed chisels give you the choice of broader breaking or more focused chipping depending on the surface and the task.

The 1.7 litre fuel tank gives you petrol-powered operation for remote or open-site use, while the listed fuel consumption of up to 0.6L/h helps buyers gauge running time between refills. Impact frequency is stated at 770 to 1500 bpm, with impact energy up to 55J, giving the machine the force needed for tough masonry and concrete work. Max speed figures are listed up to 6500rpm, and the unit is supplied with both flat and pointed chisels so you can get started on common demolition and trenching jobs straight away. For repeated breaking work, having both chisel types included is useful and helps keep the machine ready for different surfaces.
