The most powerful (70 J) oil-cooled (5W30) demolition hammer in its class. Designed for demolition of reinforced concrete, such as footings, slabs reinforced with A-III and A-0 steel, scraping ceilings or compacting soil, with the appropriate tip (YT-47385 to be purchased separately). passes the test when forging horizontally, thanks to the short piston stroke and high impact frequency (not causing the effect of pushing the operator with the hammer away from the wall when held horizontally, instead of forging, which is characteristic of many hammer designs on the market) effective oil cooling protects the machine from overheating during heavy work and, thanks to its lower viscosity than grease, causes less friction resistance in the mechanism, significantly extending the life of the machine anti-vibration handle protects the hammer operator from the adverse effects of vibration and reduces fatigue caused by holding the hammer in operation large diameter of the piston of the electropneumatic mechanism guarantees high energy of a single blow (as much as 70J), which allows to effectively hammer a significant volume of concrete, per unit of working time Hex chuck (diameter 30 mm) works with self-sharpening chisels for reinforced concrete, shovels for digging in hard soil, rammer for soil, and classic chisels from picks to wide chisels (35, 75, 125 mm). Yato index range from YT-47370 to YT-47385).
