Klein Tools 32500MAG Magnetic Multi-Bit Screwdriver

The Verdict

If you’ve ever dropped a #2 Phillips screw into the dark recesses of a gang box at 11 p.m., you already know why the Klein Tools 32500MAG exists. This is the screwdriver Klein built for electricians, but it’s honestly useful for anyone who works on appliances, furniture, or anything with a fastener more than two inches from your face.

Let’s be clear about what this isn’t: it’s not a ratcheting driver, it’s not a 20-bit survival kit, and it’s not going to replace your impact driver. What the 32500MAG does is nail the fundamentals—strong magnet, solid bit retention, and a handle that actually feels good after 200 screws.

What’s in the box
You get the driver with 12 bits pre-loaded: six in the handle storage and six in the shaft. That includes Phillips #1 and #2, flat 5/16 and 1/4, Torx T15 and T25, and square #1 and #2—the exact mix you’ll reach for on outlet covers, switch plates, terminal lugs, and cabinet hinges. The bits are 1-inch long, standard 1/4-inch hex, so replacements are cheap and available anywhere. The shaft itself is 3/8-inch steel, and the whole tool weighs about 8 ounces—light enough to carry daily, heavy enough to feel solid.

Performance and build quality
The magnetic tip is the headline feature, and it delivers. It holds a #2 Phillips screw vertically even when you shake the driver lightly, and it keeps smaller screws from wandering during startup. One electrician reviewer put it bluntly: “The magnet is strong enough to hold a screw upside down, which is exactly what I need when working above my head.” That tracks with my testing—I drove a dozen screws into drywall anchors and lost zero fasteners.

The bit retention is also worth noting. Klein uses a neoprene collar that grips the inserted bit firmly; there’s no wobble, which means less stripped heads on worn screws. The handle is a soft, cushioned material with a triangular profile that resists rolling off a ladder—a small detail that matters more than you’d think.

Where it falls short
The bit storage is the main compromise. To swap bits, you pull off the end cap, which then doubles as a mini extension holder. It works, but it’s not fast. If you’re switching between Phillips and Torx every few minutes, you’ll feel the friction. A side-loading bit holder would have been smarter for a tool at this price point.

Also, the shaft is not hollow, so you can’t drive screws that sit deep in a recessed hole—say, a long machine screw inside a junction box. You’ll need a separate stubby or a hollow-shaft driver for those jobs. And while the magnet is strong, it’s not a magnetic tip and shaft—only the tip, so don’t expect it to hold screws along the full length.

Who should buy this
Buy it if you’re an electrician, an HVAC tech, or a DIYer who does a lot of outlet and switch work. The bit selection is tailored to electrical tasks, and the magnet will save you from the most common annoyance in that trade. It’s also a great second driver for a tool bag—small enough to toss in without thinking.

Skip it if you need a do-everything driver for furniture assembly or heavy mechanical work. You’ll want more bits, a ratcheting mechanism, or a hollow shaft. This is a specialist tool wearing a generalist’s body.

FAQ
Is the magnet strong enough for hex-head screws?
Yes, the tip magnet holds steel screws of most sizes—up to about #10. Larger lag bolts are too heavy; use a separate magnetic holder for those.

Are the bits replaceable?
Yes, they’re standard 1-inch 1/4-inch hex bits. Klein sells replacements, but any brand’s bits fit.

Does it work for left-handed users?
Yes, there’s no ratchet or directional mechanism, so it’s fully ambidextrous.

The Verdict
The Klein Tools 32500MAG earns its 4.7-star rating by doing one thing extremely well: keeping screws where you put them. The magnetic tip is genuinely strong, the build quality is Klein-solid, and the bit selection covers 90% of electrical and household tasks. The internal bit storage and non-hollow shaft are the tradeoffs, but they’re minor if you’re not a production tradesman.

Buy it if you want a reliable, magnetic multi-bit driver for electrical work or general home repair.
Skip it if you need a ratcheting driver or a hollow shaft for deep fasteners.

Rating: 4.6/5 — A well-executed specialist tool that most homeowners will appreciate.
