Sumake pneumatic wrench: reviews, specifications, descriptions of models
User reviews of the SUMAKE ST 5540K impact wrench note the tightness of the pneumatic line, the excellent price-quality ratio, and the ease of adjusting the rotation speeds.
The power source in a pneumatic threaded service device is the energy of compressed air generated by a compressor and supplied through a hose to the equipment. The Sumake impact wrench, manufactured at a high-tech enterprise in Taiwan, proved to be an excellent example of pneumatic tools.

Average price category, but the quality is high. The parts fit well, there is little noise. Recommend.
Impact wrench SUMAKE ST-M1001
The model is aesthetically attractive, has an impeccable pistol shape. The dimensions of the unit with a weight of 2,1 kg are 215x208x72 mm. The body is made of durable metal, which reliably protects internal components from mechanical damage.
The Rocking Dog impact mechanism produces a series of pulses on the head of the element being processed, intensively influencing and quickly screwing the fastener. The reverse function facilitates the reverse operation. It takes 5 seconds to process one, even an old hardware. The tightening torque, based on the needs, can be adjusted by the master with the button on the handle.

Vasiliy:
The torque is weak, but this is not the fault of the manufacturers. The model must be selected according to the type of work.
Impact wrench SUMAKE ST-5544
The aluminum body of the tool is covered with a modern composite material, which in combination ensures the durability of the equipment. The powerful thread wrapper is ready to do its job for hours without overheating the 6-blade rotary motor.
Sumake Air Tool Set
First you need to attach the nozzle to the spindle, then attach it to the head of the fastener and pull the trigger. Compressed air from the compressor through a sealed pneumatic line will go to the rotor, the spindle will begin to rotate. Next, the shock function is connected: with a torque of 624 Nm, a threaded connection of any complexity (but not larger than M16 mm) will be undermined and successfully unscrewed.

Anton:
This item is not for home use. But in a car repair shop, it's the most important piece of equipment. Works non-stop for the entire shift. A very interesting development is the SUMAKE ST 5554 pneumatic angle wrench. The unit performs specific narrowly focused tasks, since the spindle in the design is located perpendicular to the rotor. Such equipment is good to use in places with difficult access to fasteners. I recommend both models.
Impact wrench SUMAKE ST-55443
To work with threaded parts up to M16 mm, a reliable SUMAKE ST-55443 device has been created. The high performance of the equipment is ensured by the 2-hammer Twin Hammer percussion mechanism. Already at the start, it creates a powerful power moment (813 Nm) and a balanced impact. Thanks to this circumstance, the SUMAKE ST-55444 wrench successfully works in heavy duty, copes with tight, soured hardware.
The well-thought-out pistol shape and the handle covered with a non-slip pad make it easier to return the tool to the operator's hand without causing physical fatigue for a long time. For the material of the case, metal is taken that is resistant to mechanical stress and corrosion.

Garik:
Really good device, works for a year without any complaints. Before that, there was a SUMAKE ST 5549AK pneumatic wrench, which did not suit the low torque. And here is strength and power.
Impact wrench SUMAKE ST-5544SH
The device of a thread wrapping machine is simple: a housing that houses an air motor, a switch, a reverse rotation mechanism, and a speed controller (this model does not have it). In front of the pistol type of the device is a spindle in the form of a 4-sided half-inch.
A 1 mm air hose is attached to the bottom of the gun handle with a 4/9,5F female thread. Nearby is an exhaust valve with a silencer. The latter reduces the noise level produced by the unit to 93-96 dB.
Sumake pneumatic ratchet
Simple equipment does not require special operator skills: the SUMAKE ST-5544SH nutrunner is easy to operate, maintenance is rarely required. It is important to combine the hardware maintenance device with the compressor station: the compressed air consumption of the pneumatic wrench should not be higher than the performance of the gas blower.
