Pachmayr's 10-piece screwdriver set is designed specifically for gunsmiths and firearms enthusiasts. The grips feature a unique three-wing, Torq Grip design. The wings provide a superior gripping surface for maximum turning power while preventing the driver from rolling away. The tips are magnetized and parallel ground for an exact fit for most rifle and handgun slotted screws. In addition, the set includes T-10 and T-15 size 6-lobe drivers as well as a 5/32" hex driver.
