The most powerful (70 J) oil-cooled (5W30) demolition hammer in its class. Designed for the demolition of reinforced concrete, such as footings and slabs reinforced with A-III and A-0 steel, it can also be used for scraping ceilings or compacting soil, with the appropriate tip (YT-47385 sold separately). It passes the test when forging horizontally, thanks to its short piston stroke and high impact frequency, which prevents the operator from being pushed away from the wall when holding the hammer horizontally—a common issue with many hammer designs on the market. Effective oil cooling protects the machine from overheating during heavy work and, due to its lower viscosity compared to grease, results in less friction resistance in the mechanism, significantly extending the machine's lifespan. The anti-vibration handle protects the hammer operator from the adverse effects of vibration and reduces fatigue caused by holding the hammer during operation. The large diameter of the piston in the electropneumatic mechanism guarantees high energy for a single blow (up to 70J), allowing for the effective demolition of a significant volume of concrete in a short period of working time. The hex chuck (30 mm diameter) works with self-sharpening chisels for reinforced concrete, shovels for digging in hard soil, a rammer for soil, and classic chisels ranging from picks to wide chisels (35, 75, 125 mm). Yato index ranges from YT-47370 to YT-47385.
