The tubular head of the SUPERCRAFT mallets is filled with steel shot. The resulting effect is that the energy of the steel shot is transferred with a slight delay when the mallet's contact surface hits the workpiece. The reduced rebound allows the impact energy to be absorbed with perfect efficiency. The result is an impact of exceptional magnitude. What is more, SUPERCRAFT mallets allow for work with greatly improved safety, reduced strain on the joints, and greater noise-dampening when compared to ordinary steel mallets. The replaceable inserts offer outstanding impact qualities and are guaranteed to combine maximum strength with unique durability. They consist of extruded and extremely homogeneous materials. Compared to injection molded plastic inserts, they are therefore considerably more wear-resistant and durable and will never chip even in sub-zero temperatures. This version comes with a break-proof steel tube handle and an ergonomically shaped non-slip rubber grip. All weld joints are completely robot-welded. Extremely tight and of premium quality, a welded connection between impact plate and hammer head keeps the steel shot filling from escaping even under maximum load. The wear-resistant powder coating prevents corrosion.
