The Klein Tools Ratcheting Fastbit Tru-Grip Screwdriver enables forward, fixed, and reverse ratcheting for faster driving. The Fastbit collar on the handle quickly releases the double-ended bit, allowing you to flip between the #2 Phillips and the 6 mm slotted-end quickly and easily. Compatible with most 1/4-Inch bits longer than 1-1/2-Inch in length, its passive locking mechanism securely locks bits into handle.
