Wiha TorqueVario-S ESD Torque Screwdriver (28500) with Wiha 4 mm Micro Bit Set (75968)。

Support Q&A
1

------Question for 28500 Please Put your question below------

  1. Can the TorqueVario-S (28500) directly accept the 4 mm hex micro-bits from the 75968 set?

  2. If not directly compatible, does Wiha offer an official adapter that allows the TorqueVario-S to use 4 mm micro-bits?

  3. For achieving a precise torque setting (e.g., 2 in-lbs / 0.226 Nm), does Wiha recommend using the standard Torque Interchangeable Blades instead of micro-bits?

  4. Is there a recommended Hex bit/blade option specifically designed for the 28500 for torque-critical applications?

I would appreciate your guidance so I can select the correct accessories for my torque screwdriver.

Thank you very much.

Hello hsueh-han_chen and welcome to the DigiKey TechForum.

From what I can see on the manufacturers page it does appear that the 28500 is compatible with the bits from the 75968. There is part number 28895, which is a set that includes the 28500 handle and that includes some of the same if not all the same bits as the 75968.
Being that the set that they offer includes the microbits, my assumption would be that those are the recommended bits for that handle.
