Adjustable torque wrench is suitable for fastening and tightening nuts and Spring collets properly. Use them every day in order to reach a longer tool life and better cutting performance.

While setting a tool it is extremely important to tighten it appropriately. If not effectively tight indeed, cutting tool could slide away from the tool holder during the working process. On the other side an excessive tightening can cause damages to the tool holder or spring collet or the tool itself.

The wrench indicates when the torque (40-70Nm for DR1 and 60-70Nm for DR2) is reached with a strong noise.
