Wheeler 89-Piece Professional-Plus Gunsmithing Screwdriver Set - Precision Tools for Firearm Maintenance

The Wheeler 89-Piece Professional-Plus Gunsmithing Screwdriver Set is purpose-built for anyone who maintains, repairs, or restores firearms. Whether you're a professional gunsmith, a serious hobbyist working on your own rifles and shotguns, or someone who wants to avoid stripping fasteners on a valuable gun, this set contains the bits and handles you need to work safely and precisely on any firearm—from modern tactical rifles to antique shotguns and revolvers.

The heart of any screwdriver system is the bit selection, and Wheeler engineers invested real time here: they measured fasteners on over one hundred different firearms, modern and vintage, to ensure this set covers everything you'll encounter. The result is 54 hollow-ground flat bits (ranging from .120"×.020" to .360"×.070"), including duplicates of the thinnest sizes—because quality gunsmith work sometimes calls for a replacement if a delicate bit breaks on a frozen screw. Add eight Allen bits, four Phillips bits, and three Torx bits for scope rings, bases, and other hardware, and you're prepared for most standard fasteners across the gun cabinet.

What sets the Professional-Plus apart from basic gunsmithing kits is the 15 specialty bits included here. These tackle less common screw profiles, help with scope base installation, and include a small pin punch function for times when you need a precision tool that's not quite a traditional punch. Two driver handles—a full-size handle for leverage and a shorter "Close Quarters" handle for finesse work in tight spaces—plus a 3-inch extension with magnet and a hex-to-square adapter give you flexibility on the bench or at the range. Both handles feature magnets to hold bits secure. All bits are forged from S2 tool steel and hardened to 56–58 Rockwell C for durability and edge retention. Everything ships in a durable custom storage box sized for the bench or a range kit.

This is the set that prevents costly mistakes: stripped screw slots diminish a gun's value and require expensive professional correction. The Wheeler Professional-Plus gives you the right tool for every screw you're likely to encounter, so your work stays clean, your firearms stay pristine, and your maintenance stays productive.

Frequently Asked Questions

Will this screwdriver set work on all my firearms?

Wheeler designed this set by measuring fasteners on over one hundred modern and antique firearms. The 54 flat bits, combined with Allen, Phillips, and Torx options, cover the vast majority of screws you'll encounter on rifles, shotguns, revolvers, and vintage guns. However, if you own obscure or specialized firearms, you may occasionally need an uncommon bit not included here.

Why are there two of the thinnest flat bits?

Professional gunsmiths know that ultra-thin bits can break when working on corroded or extremely tight fasteners. By including duplicates of the thinnest sizes, you won't be left stranded mid-job if one breaks. Replacement bits are also available in three-packs at modest cost.

What's the difference between the regular handle and the "Close Quarters" handle?

The full-size handle is ideal for general gunsmithing work where you need leverage and control. The shorter, slimmer "Close Quarters" handle is designed for finesse work in tight spaces or with smaller bits where a full-size handle would be awkward. Both include magnets to hold bits securely in place.

What are the specialty bits used for?

The 15 specialty bits handle less common screw profiles found on certain firearms and accessories, assist with scope base installation, and include a pin punch function for precision work when you need a tool beyond a standard screwdriver.
