Screwdrivers are the most important and most-used gunsmithing tools. 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.” 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. Keep your gun looking and operating as good as new! Avoid costly damage that ruins the look and value of your guns! 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. The 54 Hollow-ground flat bits range in size from .120″x.020″ to .360″x.070″, and includes doubles in the thinnest sizes. (Any gunsmith will tell you that you’re occasionally going to break the ultra-thin bits on stubborn screws. 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 difference in the “basic set” and the “professional set” lies in the 15 ingenious “specialty bits” that are included in the “professional” 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.
