The Koswork Quick Release 1/4″ Drive Hex Driver Set KOS13210 is a high-quality professional tool set designed for demanding RC racers and competitive drivers . It combines multiple functions in a single tool , enabling particularly fast and efficient work at the racetrack and in the workshop.

Thanks to the quick-release mechanism, the bits are not only held magnetically but also mechanically locked. This ensures the bits are absolutely secure – even during fast-paced work or when using electric screwdrivers . The 1/4″ hex bits are fully compatible with cordless screwdrivers and power tools.

The lightweight aluminum handle fits comfortably in the hand and offers optimal control. A particularly practical feature: unused bits can be stored inside the handle , keeping things tidy and making transport easier. A well-designed, robust tool for anyone who refuses to compromise in RC sports.
