Screwdriver Bit Holder Wiha 2970

The Wiha 2970 torque adapter converts compatible slimVario and LiftUp screwdrivers into a torque-controlled tool for safe work on live parts up to 1,000 V AC. Individually tested to 10,000 V AC and manufactured to IEC 60900, this adapter delivers a release accuracy of ±10% and a torque limit that prevents over-tightening and material damage. It is compatible with the Wiha slimBit system and holds 75 mm slimBits securely; bit holders or blades are not included.

Advantages

The adapter reduces costs by preventing warranty claims through correct torque application and increases efficiency by avoiding damage that would require rework. It is fully compatible with the Wiha slimBit system and provides electrical protection through individual high-voltage testing, enabling safe use on live electrical parts.

How to use

Attach the easyTorque adapter to a compatible slimVario or LiftUp screwdriver and insert a suitable slimBit (75 mm slimBit recommended). Tighten screws until an audible click is heard and the yellow ring and red adapter rotate in opposite directions, indicating the preset torque has been reached. The adapter will release at the set torque, ensuring controlled tightening with a tolerance of ±10%.

Usage recommendations

Use the adapter only with compatible Wiha slimVario or LiftUp screwdrivers and appropriate slimBits. Do not use bit holders or blades that are not specified for the system. Verify the required torque range for your application and ensure the adapter’s maximum torque fits the task. Regularly inspect the adapter for damage and follow IEC 60900 guidelines when working on live parts.
