Wheeler’s Deluxe Gunsmithing Screwdriver Set belongs on every gunsmithing bench. The bits are made from S2 tool steel and hardened to 56-58 Rockwell “C”. The 54 Hollow-ground flat bits range in size from .120″x.020″ to .360″x.070″ and includes doubles in the thinnest sizes. This set includes two each of the very thinnest bits, a complete selection of Phillips, Allen and Torx bits to cover scope rings, bases, recoil pads. The 15 “specialty bits” that are included are great for installing scope bases. The set comes with two handles made from overmolded plastic, a regular size handle that’s good for most jobs and a slimmer, shorter “Close Quarters” handle that is good for finesse work with smaller bits.
