As my tests showed this chisel hammer steel from Bosch provides incredibly powerful blows for effortless chiseling in concrete and masonry.The tapered design contributes to precision and control, while the heat-treated steel construction ensures durability. The only downside is that it may be a bit heavy for prolonged use, but the exceptional results justify the weight. Highly recommended for professionals and DIY enthusiasts who demand outstanding performance from their industrial HAND tools..
