The SUMAKE STC575 is a powerful 3/4" pneumatic impact wrench designed for demanding fastening and loosening applications in automotive workshops, commercial vehicle service centres, industrial facilities and maintenance operations.

With a maximum torque of 1695 Nm and a free speed of 8000 RPM, this tool is suitable for working with heavily loaded fastening components.

The wrench features a Twin Hammer impact mechanism, delivering powerful rotational impacts to help loosen tightly fastened or seized nuts and bolts.

Its composite housing helps reduce overall tool weight while maintaining a robust construction. Weighing just 2.70 kg, the wrench is convenient to handle during repetitive maintenance tasks.

The tool operates at 6.3 bar air pressure and has a manufacturer-specified average air consumption of 540 L/min. A suitable air compressor and correctly sized pneumatic supply system are required for optimal performance.

Powerful 1695 Nm Maximum Torque

The 1695 Nm maximum torque makes the wrench suitable for demanding loosening applications.

It can be used for servicing vehicle chassis, wheels, mechanical assemblies and other fastening systems.

The supplier does not separately specify working tightening torque and maximum breakaway torque.

Twin Hammer Impact Mechanism

The Twin Hammer mechanism uses two hammers to deliver rotational impacts.

Its advantages include:

• powerful impact action;

• efficient torque transmission;

• suitability for intensive maintenance;

• effective loosening of tightly fastened components.

3/4" Square Drive

The wrench features a 3/4" (19.05 mm) square drive compatible with suitable impact sockets.

This drive size is commonly used for larger fastening components requiring higher torque.

Only use sockets specifically rated for impact wrench applications.

8000 RPM Rotational Speed

The 8000 RPM rotational speed allows fast running down and removal of fasteners when high impact force is not required.

This helps improve efficiency during repetitive assembly and repair tasks.

Lightweight Composite Housing

The wrench features a composite housing and weighs 2.70 kg.

Its relatively low weight improves handling and helps reduce operator fatigue during extended use.

Pneumatic Operation – 6.3 Bar

The tool requires 6.3 bar operating air pressure.

The manufacturer specifies an average air consumption of 540 L/min.

Ensure the compressor, air hoses, fittings and pressure regulator can provide adequate airflow.
