Whether you are a professional or in-home gunsmith, the WheelerA(R) 89 Piece Professional Gunsmithing Screwdriver Set is a must-have staple in your toolset. Unlike other screwdriver suppliers, Wheeler's engineers measured the screws on over one hundred modern and antique firearms to ensure that we offered specialty bits for every situation. Whether you are working on a BrowningA(R) Superposed, a RemingtonA(R) 700, a Smith & WessonA(R) revolver, or a ColtA(R) single action, you will find that there is a bit to fit every screw on your gun. The two included drivers feature magnetized tips and rubber over-molded handles that improve ergonomics and grip while reducing hand strain. The driver shafts and bits all have a black phosphate coating that prevents rust and corrosion and extends tool life; guaranteeing that your tools will look great for years to come. All the contents are neatly organized and secured in a premium latching hard case that easily stacks on top of other Wheeler screwdriver sets for smart, convenient storage.
