This on tool storage solution is made with non-marring rubber to protect the work surface from scratches and damage. The accessory bit holder also provides reliable retention, making sure the bits are accessible when needed and not lost during the workday. Versatility of the bit holder allows the capability of holding up to 4 1/4" shank bits at one time.
