Description
Anyone who has ever slipped a hardware-store screwdriver out of a tight receiver screw and left a nasty burr behind knows why a proper gunsmithing set matters. The Wheeler 89-Piece Professional Gunsmithing Screwdriver Set (2023 Edition) tackles that problem head-on with hollow-ground flat bits that seat all the way into the slot for maximum contact. Wheeler's engineers measured screws on over a hundred modern and antique firearms while building this lineup, so there's a bit to fit just about everything from a Remington 700 to a Smith & Wesson revolver to an old Colt single action.
What You Get in the Wheeler 89-Piece Set
Inside the custom-molded case you'll find 54 hollow-ground flat bits, 15 specialty bits, 8 Allen bits, 4 Phillips (#0 through #3), and 3 Torx (T10, T15, T20). The specialty bits cover the odd stuff that usually sends you hunting for a one-off tool, including Weaver and Ruger scope ring clamp bits, Redfield and Leupold windage screw bits, a Mauser stock cross bolt bit, and the Ruger/Colt single action base pin latch nut bit. There's also a 2-1/4 inch shaft extension and a hex-to-square drive adapter tucked in for good measure.
Why the Hollow-Ground Bits Make a Difference
Every bit is machined from S2 tool steel and finished in black phosphate to fight rust and stretch out the tool's life. The hollow-ground grind means the tip stays parallel where it meets the screw slot instead of tapering like a common wedge-shaped driver, which is what keeps it from camming out and marring your gun. Both the short and long 1/4-inch drivers carry rubber over-molded handles and magnetized tips, so bits swap fast and stay put while you work.
The hinged case includes a bit location guide so you always know where each piece lives, and it's built to stack alongside other Wheeler sets on the bench. Whether you're mounting optics, adjusting a stock, tightening grips, or doing a full teardown, this is the kind of set that lives on the workbench and earns its keep.

Frequently Asked Questions
What makes the Wheeler 89-Piece set better than a regular hardware screwdriver for guns?
The flat bits are hollow-ground, meaning the tip stays parallel where it contacts the screw slot instead of tapering to a wedge like a common driver. That flush fit spreads the load across the whole slot and keeps the bit from camming out and burring up the screw head. On a firearm, where a marred screw is both ugly and hard to fix, that extra contact is the whole point.
Does the Wheeler 89-Piece Professional Gunsmithing Screwdriver Set come with a torque wrench?
No, this kit does not include a torque driver. It comes with two standard magnetized 1/4-inch drivers, the bit assortment, an extension, and an adapter. If you want to torque scope rings or action screws to spec, Wheeler's FAT Wrench is a separate tool that uses the same 1/4-inch bits.
Will this set fit both modern rifles and older firearms?
That's exactly what it's designed for. Wheeler measured screws on more than a hundred modern and antique firearms when they laid out the bit selection, so you'll find sizes for guns ranging from a Remington 700 to a Colt single action. The 15 specialty bits also cover things like scope ring clamps and windage screws that trip up a lot of generic sets.
What are the bits made of and will they rust?
The bits are machined from S2 tool steel and hardened to 56-58 Rockwell C, so they hold up to real use on stubborn fasteners. Every bit and driver shaft wears a black phosphate coating that resists corrosion and helps the tools last. Keeping them in the fitted case between jobs goes a long way too.
