DOA DHW9512 Hydraulic Impact Wrench – 9,500 Nm High-Torque Industrial Hydraulic Wrench

The DOA DHW9512 Hydraulic Impact Wrench is a heavy-duty industrial hydraulic fastening tool designed to deliver exceptional torque for the toughest bolting applications. Producing up to 9,500 Nm (7,006 ft-lbs) of maximum torque, the DHW9512 is engineered to loosen seized fasteners and tighten large bolts with consistent hydraulic power. Designed and manufactured in Italy, this professional-grade hydraulic impact wrench is built for industries that demand reliability, durability, and maximum performance in harsh working environments.

Powered by a hydraulic power unit rather than compressed air, the DHW9512 provides smooth, consistent torque without the pressure fluctuations associated with pneumatic tools. Whether working in construction, mining, oil & gas, marine, railroad, or heavy equipment maintenance, this hydraulic impact wrench delivers dependable performance day after day.

Built for High-Torque Industrial Fastening

The DOA DHW9512 is specifically engineered for fastening and loosening large industrial fasteners ranging from M24 to M56. Its heavy-duty 3-jaw hammer impact mechanism efficiently transfers striking force while minimizing internal wear, making it ideal for demanding industrial maintenance and construction applications.

With its 1-1/2" square drive, the DHW9512 easily accommodates large impact sockets used for structural steel, bridge construction, heavy equipment repair, pipeline flange assembly, and industrial plant maintenance.

Consistent Hydraulic Performance

Unlike pneumatic impact wrenches that lose power as air pressure drops, hydraulic tools provide continuous, dependable torque throughout operation. Operating on a hydraulic flow range of 20–30 L/min (5.3–7.9 GPM), the DOA DHW9512 maintains consistent performance even during prolonged use.

The integrated manual forward/reverse inverter allows operators to quickly change rotation direction, improving productivity during repetitive fastening and maintenance operations.

Engineered for Operator Comfort

Despite its impressive power, the DHW9512 is designed with operator comfort and safety in mind.

• Lightweight Ergal aluminum ergonomic handle
• Integrated hydraulic oil flow through the handle
• Mechanical trigger with built-in safety lever
• Heat-dissipating hydraulic motor housing
• Excellent tool balance for reduced operator fatigue
• Optional T-handle configuration for additional control

These ergonomic features allow technicians to work comfortably during long maintenance shifts while maintaining excellent control of the tool.
