Area of application

The torque adapter is suitable for low torques. Thanks to the BERNSTEIN bit adapter, it can easily be clamped between any commercially available holding tool and a 4 mm bit. This turns every bit holder into a torque screwdriver.

Technical description

Precise and accurate, for 20,000 clicks. Adapters are mainly suitable for manual operation. In conjunction with power-tool we recommend max. a speed of 100 rpm, with minimal click repetition. Higher speed as special model on request.
