The Bosch Custom Case System works with Impact Tough™ Bits, providing the best case for the best bits. The durable, well-designed case houses clips that allow bits to tilt-in/tilt-out. This makes it convenient and easy to access to the bits. The clips snap in/snap out of the case for easy access to carry only the bits needed. This customizable organization system helps user increase productivity by reducing time searching for the right bit.
