Galvanox 21PC Flat Bit-Kit Designed for Leatherman Multi-Too
✅ PROS
- Fits Leatherman's flat bit driver snugly with zero wobble — no adapter needed
- Includes Torx and security Torx bits, which most generic kits skip
- Bits are S2 steel with a proper 1/4-inch hex shank, not cheap stamped metal
❌ CONS
- No carrying case included — bits arrive loose in a plastic sleeve
- Flat bits only; won't work with Leatherman's older round-bit models
The Verdict
Let me save you the headache I had three years ago. I bought a “compatible” bit kit for my Leatherman Wave off Amazon, and the bits wobbled like a loose tooth in a hurricane. The Galvanox 21PC Flat Bit-Kit is not that kit. At 4.8 stars from 240 ratings, this is the one Leatherman owners keep coming back to.
What’s Actually in the Box
You get 21 bits total: 10 flathead sizes (3mm to 8mm), 4 Phillips (PH0–PH3), 3 Torx (T10, T15, T20), 2 security Torx (with the hole in the middle), and 2 hex sizes. All bits use the standard 4mm flat format that Leatherman adopted for their newer tools like the Wave+, Charge+, and Surge. The packaging is minimal — a clear plastic sleeve with a cardboard header. No case, no organizer. That’s the first thing you’ll want to address.
Build Quality and Real-World Testing
The bits are machined from S2 steel, which is the same alloy used by premium screwdriver manufacturers like Wera and Wiha. I’ve put about four months of daily use on mine — everything from tightening eyeglass screws to rebuilding a deck gate latch. None of the bits have snapped or rounded off. The Phillips heads bite properly without cam-out, and the flatheads are ground square, not tapered like cheap stamped bits.
The critical spec here is the 4mm flat shank. Leatherman’s flat bit driver uses a spring-loaded ball detent to hold bits in place. The Galvanox bits have a proper detent groove machined into the shank, so they lock in with a satisfying click. No wobble, no accidental drops. One reviewer put it perfectly: “Finally a bit set that doesn’t feel like I’m using a butter knife. These lock into my Wave+ like they were made by Leatherman themselves.”
Where It Falls Short
Two honest complaints. First, the lack of storage is a genuine annoyance. The provided sleeve is flimsy, and bits have a habit of sliding out if you toss them in a backpack. I ended up buying a cheap canvas roll-up organizer for mine. Second, this kit is useless if you own an older Leatherman (pre-2015 models like the original Wave or Charge) that uses the round 5mm bits. Check your tool before ordering.
Also worth noting: the bits are slightly shorter than Leatherman’s own branded ones (about 0.5mm less usable length). In practice, this rarely matters, but if you’re reaching into a deep recessed screw, you might feel the difference.
Who Should Buy This
This kit is for anyone who owns a modern Leatherman and wants to stop carrying a separate screwdriver. It’s especially good for:
- EDC carriers who want a compact bit set for their pocket organizer
- Bike mechanics who need Torx and security Torx for brake rotors and derailleurs
- Office workers who just want to tighten glasses and laptop screws without hunting for the toolkit
Skip it if you need hex bits larger than 4mm (the included hex sizes are tiny) or if you work on appliances with mixed drive types — the missing Phillips #1 and #2 coverage is fine, but you won’t get Robertson or Pozidriv here.
FAQ
Q: Will these bits fit my Leatherman Skeletool? A: No. The Skeletool uses a standard 1/4-inch hex driver, not the flat 4mm format. You need a different bit set for that tool.
Q: Are these bits magnetic? A: The bits themselves are not magnetic. The driver on your Leatherman holds them mechanically, so that’s fine. But if you’re working in tight spaces, you’ll want to add a magnetic bit holder.
Q: How do these compare to Leatherman’s official bit kit? A: The Galvanox kit costs roughly 40% less and includes security Torx bits that Leatherman’s own kit omits. The steel quality is comparable. The main advantage of the official kit is the included nylon case.
The Verdict
Buy it if you own a modern Leatherman and want a reliable, affordable bit set that actually stays put. The S2 steel and precise machining make this a genuine upgrade over generic Amazon bits, and the security Torx coverage is a thoughtful addition.
Skip it if you need a storage case, own an older round-bit Leatherman, or require specialty drives like Robertson or Pozidriv.
Rating: 4.6/5 — loses half a star for the flimsy packaging, but the bits themselves outperform their price point. For under $20, this is the flat bit kit I’d buy again without hesitation.
