Dera 1800W electric demolition hammer

Key Specifications

• Power Input: 1800 Watts.

• Impact Energy: Usually rated in the 40–50 Joules range, providing the force needed to crack high-strength concrete.

• Chuck Type: Most models in this power class utilize a 30mm Hex (hexagonal) shank system, which is standard for heavy-duty demolition hammers to prevent the bit from twisting under high torque.

• Blows Per Minute (BPM): Typically around 1400–1800 BPM.

• Weight: Generally ranges from 15kg to 18kg. This weight is intentional—it provides the downward force necessary to break through materials without the operator having to force the machine.
