Lyman�s screwdriver sets provide all the bits needed by gunsmiths and all those who work on firearms. These complete sets come with bits for slotted screws, hex screws, Torx screws, and Phillips screws; in addition to an assortment of specialty bits. The specialty bits include a Weaver scope ring bit, Glock front sight bit, 1911 grip bushing bit, as well as .062�, .093� and .118� pin punches. The sets also include a ratchet wrench so the maximum torque can be applied to those tough-to-remove screws. The bits for slotted screws are hollow ground, so they properly fit screw slots and prevent cam-out which creates ugly, damaged screw slots. The sets are packed in compact, convenient storage cases.
