Lyman™ Tool Kit 68 Piece - 7991361 Pachmayr’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, 6-lobe 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.
