Pneumatic impact wrench 1/2" STT-17

Ideal for the workshop

STT-17 is a 1/2" pneumatic wrench powered by compressed air at 6.3 bar. It is designed for screwing/unscrewing screws and nuts during various types of workshop work. It will be perfect for automotive service shops, for example for mounting/removing wheels of cars and vans.

Twin hammer – instant power

The wrench is equipped with a solution known as "twin hammer" - a double hammer, or double impact mechanism. Its design is based on the use of a double hammer, which, striking simultaneously from both sides, generates a balanced and powerful impact. As a result, the maximum torque of the wrench is released as soon as it starts working - with the first revolutions of the 6-blade rotor.

Maximum efficiency

The wrench's maximum torque is 1,700 Nm, which enables fast and secure loosening of even the most caked-on and corroded threaded connections. 1/2" square driver allows the use of a wide range of professional 1/2" impact sockets. The tool maintains efficiency and performance in the toughest operating conditions, while always ensuring precision and accuracy.

Torque adjustment

The STT-17 wrench offers a total of 4-stage torque level adjustment:

• 3-stage tightening torque adjustmen,
• 1-stage loosening setting (loosening is done at full power).

Professional functionality

The STT-17 impact wrench was prepared for professionals looking for proven solutions, so the STT-17 has a number of advantages typical of high-end professional pneumatic tools, such as:

• stable operation of the mechanism,
• ability to carry heavy loads,
• repeatable torque value,
• self-lubrication.

Robust and lightweight design

The mechanism of the STT-17 wrench is enclosed in a compact "pistol" housing, made of durable glass-fiber-reinforced composite, well able to withstand contact with lubricants and workshop "chemistry". The design of the wrench makes it possible to service and replace parts. The small weight of the wrench - only 2.1 kg - and perfect balance significantly facilitate the free operation of the tool.

Comfort of use

The ergonomic, properly shaped handle is covered with a soft non-slip material that is pleasant to the touch. It is a so-called soft grip, which helps dampen vibrations, insulates the hand well from low temperatures and provides a more secure grip on the tool. The trigger switch built into the handle sits perfectly under the finger. It moves with just the right, slightly perceptible resistance, so that the actuation and operation of the wrench remain under the user's control.

Components of the set

The wrench is packaged in an aesthetically pleasing cardboard box, in which the buyer will find, in addition to the wrench, the following equipment: quick-connector and user-manual.
