The head tube of the Supercraft hammers is filled with steel shot. This causes the shot filling to follow with a delay upon impact of the striking surface on the workpiece. The reduced rebound allows for optimal utilization of the striking energy, enabling very powerful blows. Furthermore, working with Supercraft hammers is significantly safer, gentler on the joints, and quieter than with conventional steel hammers.

The interchangeable striking inserts offer outstanding striking properties and guarantee maximum strength with the highest durability. They are made from extruded, extremely homogeneous material. Compared to injected plastic inserts, they are significantly more wear-resistant and robust, and they do not splinter even at low temperatures.

The 3-component handle contains a break-resistant, flexible fiberglass core, wrapped in ergonomically shaped polypropylene and an elastomer layer that ensures a secure grip even with oily and greasy hands. The durable powder coating of the head protects against corrosion.

All weld seams are completely robot-welded. An extremely dense and high-quality weld connection between the impact plate and hammer head prevents the escape of the shot filling even under maximum load.
