The Tagred TA8557 is a 1" pneumatic impact wrench with 4200 Nm breakaway torque at 8 bar and a Twin Hammer mechanism, designed for professional use in heavy-duty applications — ideal for truck services, construction machinery, and industrial equipment where access to tight spaces can determine the speed of intervention.

The Twin Hammer mechanism with two hammers simultaneously striking the shaft from both sides produces exceptionally high torque from the first turns — the real advantage over a single hammer mechanism becomes evident when dealing with rusted or overtightened nuts, where initial shocks are critical. With a maximum speed of 6000 rpm, the TA8557 is also one of the fastest impact wrenches in its category.

The impact wrench features 3 independent adjustable tightening and loosening settings, allowing precise control of the force in each direction — torque is independently adjustable for tightening and loosening. The 14mm socket connection with a recommended 12mm diameter hose ensures sufficient air flow to achieve the maximum torque of 4200 Nm.

• 4200 Nm breakaway torque at 8 bar
• 6000 rpm maximum rotational speed
• Twin Hammer — 2 hammers simultaneously
• 34 cm total length

The TA8557 allows access to areas where longer impact wrenches cannot reach, offering maximum torque from the initial impacts and 3+3 adjustable levels. It is mainly used in truck services, construction and agricultural machinery, and heavy industry.

Advantages include:

• Short length of 34 cm — access to narrow spaces
• Twin Hammer — torque from the first impact
