Technical Features and Advantages of the Sumake ST-5578H Impact Wrench
Developed for high productivity and durability in machine shops and maintenance departments, the Sumake ST-5578H 3/4" square drive impact wrench combines a balanced construction with exceptional breakaway power. The compact pistol-grip design with an overall length of just 220 mm allows for agile work even in tight operating spaces.
Dual Mass Mechanism and Power Control
- Twin Hammer Impact Mass: The double hammer mechanism ensures immediate and uniform torque delivery, reducing the vibrations perceived by the operator.
- Power and Reverse Selector: The rear control allows you to easily set 3 progressive power levels during the screwing phase and to engage reverse at the maximum power output (1,356 Nm) for the removal of stuck bolts.
- Air Exhaust from the Handle: The exhaust duct positioned at the base of the handle channels the air downwards, avoiding turbulence or lifting of dust into the work area.
Air Supply Specifications
The tool requires a 3/8" threaded air connection and a recommended 13mm internal diameter air hose to ensure proper airflow (up to 540L/min at full load).
