Screwdrivers are the most important and most-used gunsmithing tools. Wheeler’s® Deluxe Gunsmithing Screwdriver Sets belong 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. These bits are made from S2 tool steel and hardened to 56-58 Rockwell “C”. Unlike other screwdriver suppliers,Wheeler’s engineers measured the screws on over one hundred modern and antique firearms to make sure that we offered bits for every situation. Whether you’re working on a Browning® Superposed, a Remington® 700, a Smith & Wesson® revolver, or a Colt® single action, you’ll find that there’s a bit to fit every screw on your gun. Any gunsmith will tell you that you’re occasionally going to break the ultra-thin bits on stubborn screws. The 89 and 72 Piece sets include 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 sets also include a complete selection of Phillips, Allen, and Torx bits to cover scope rings, bases, recoil pads, and the like. The difference in the 72 pc. and the 89 pc. set lies in the 15 ingenious “specialty bits” that are included in the 89 pc. set. These bits are great for installing scope bases, getting you out of a pinch by providing a small pin punch when you really need it, and keeping once-in-a-while lifesaver tools at your fingertips.
