Wheeler's Deluxe Gunsmithing Screwdriver Set is the kit that belongs on every gunsmithing bench the well thought-out bit selection will put an end to burred, buggered, busted up screw slots on any gun that comes your way. The bits make up the heart of any screwdriver set, and Wheeler's are the finest available. They're 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, which means you'll never be stuck in the middle of a job without the proper bit. The set also includes a complete selection of Phillips, Allen, and Torx bits to cover scope rings, bases, recoil pads, and the like. The 15 "specialty bits" that are included are great for installing scope bases. Set comes with two handles made from comfortable overmolded plastic, the first is a regular size handle that's good for most jobs, and the second is a slimmer, shorter "Close Quarters" handle that is good for finesse work with smaller bits.
