I do not own any Wiha magnetic screwdrivers but I do own the Wiha bit you are asking about and I am very pleased with he quality and performance of the bit  The bit works with any of my "standard" magnetic drivers or bit extensions (e.g. Dewalt).  Please be aware that there are some specially produced magnetic drivers that may have a shorter or longer magnetic "shaft seat" in the driver that standard length bits may not work.  I am only sharing this because I wold not be surprised if the the bit does not work in ALL Wiha magnetic screw drivers.  You may need to adjust your question to a specific Wiha magnetic driver.
