Screwdrivers are one of the most important and most used gunsmithing tools. Wheeler's 43 Piece Gunsmithing Screwdriver Set belongs on every gunsmithing bench. 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 are working on a Browning Superposed, a Remington 700, a Smith & Wesson revolver or a Colt single action, you will find that there is a bit to fit every screw on your gun. Features: Hollow-ground flat bits create precise fit to prevent damage to screws and firearms Textured rubber handles for enhanced comfort and grip Molded case organizes bits and drivers Bits are coated in black phosphate to prevent rust
