Power Torque Tools

Tohnichi’s lineup of power torque tools includes pneumatic torque screwdrivers and pneumatic torque wrenches. Our pneumatic torque screwdrivers are equipped with a torque control mechanism we developed and perfected ourselves to promote precision torque control. Our lineup of power torque screwdrivers includes both pneumatic and electric models. Our lineup of power torque wrenches includes pneumatic semi-automatic models, electric semi-automatic models, fully automatic pneumatic models, and fully automatic electric models.

U/UR

• Application: For plastic screws and tapping screws.
• For large volume tightening of machine screws (M2-M6) requiring high torque accuracy.
• Straight version of AUR model.
• High speed and high accuracy tightening with lever activation.
• Torque setting is easy to adjust by knob and scale.
• Torque remains stable regardless of fluctuations in air pressure.
• Small reaction force when set torque is reached.
• UR / ULR operates bi-directionally.

AC2

• Application: For assembly and mass-production.
• Provides high speed and high accuracy by applying provisional tightening with air motor, followed by conventional torque wrench work to complete tightening.
• Regular tightening tasks using an impact wrench plus a torque wrench become part of a single process, greatly improving task efficiency.
• Provisional tightening is applied using the air motor operation, and completed in high accuracy by manual torque wrench operation.
• Accuracy improved with final tightening completed by manual torque wrench work.
• Changing tightening torque is easy with the N･m unit scale.
• Easy calibration with torque wrench tester.
