Gedore R78900550 Tool Set Gedore 3301220 High Quality Durable

Gedore R78900550 adjustable torque wrench (MPN 3301220) provides controlled screw tightening from 5 to 550 N·m with repetition-accurate, precision-like performance. The instrument gives a clearly heard and felt torque trigger and supports both clockwise and anti‑clockwise tightening by switching the mushroom head/push-through square. Supplied with a test certificate in accordance with DIN EN ISO 6789 and operating instructions, this torque wrench is designed for professional use where reliable torque control and durability are required.

Advantages

The torque wrench combines an integrated ratchet-head function with a square drive and ratchet mechanism for flexible use. Torque is set by turning the handle and the selected value is locked at the end of the handle to prevent accidental changes. An easy-to-read scale with a magnifying glass shows values in N·m and includes a 1/10 scale for precision setting. The working accuracy is ±3% of the scale set torque, ensuring consistent results across repeated operations.

Suitable for

• Controlled tightening of screws and bolts in automotive maintenance and repair
• Assembly and production tasks requiring repeatable torque application
• Maintenance work on machinery and industrial equipment
• Situations demanding both clockwise and counterclockwise torque application

Key specifications

• Model: Gedore R78900550 (MPN 3301220)
• Torque range: 5–550 N·m
• Drive type: square drive with ratchet mechanism
• Accuracy: ±3% tolerance of scale set torque
• Scale: N·m with 1/10 precision scale and magnifying glass
• Delivery: torque wrench with test certificate (DIN EN ISO 6789) and operating instructions

How to use

Set the required torque by rotating the handle to the desired value on the N·m scale, using the magnifying glass for precise alignment with the 1/10 scale. Lock the selected torque by engaging the lock at the end of the handle. Attach the appropriate socket to the square drive; select clockwise or anti‑clockwise operation by switching the mushroom head/push-through square. Apply force until the torque trigger is felt and heard, then stop tightening to avoid exceeding the set value.

Recommendations

For consistent accuracy, calibrate the torque wrench periodically and avoid using it as a breaker bar. Store the wrench with the torque set to its lowest value when not in use and follow the supplied operating instructions and test certificate guidelines for maintenance and verification.
