Saker 42 in 1 Magnetic Screwdriver Set,Multi Bit Screwdriver

The Verdict

Let me be blunt: most multi-bit screwdriver sets are landfill fodder. The bits strip, the handle cracks, and the magnet holds nothing. The Saker 42-in-1 is not that set. It’s the one you actually reach for when the cheap kit from the gas station fails you mid-project.

What’s in the box

You get a 42-piece kit: 34 standard bits (Phillips, slotted, Torx, hex, and Pozidriv), 8 security bits (the ones with holes in them for tamper-proof screws), a 1/4-inch hex-to-hex extension bar, a flexible shaft, and the main driver handle. Everything snaps into a compact 6-inch case that fits in a jacket pocket or a tool bag side pouch. As shown in the product image, the case uses a sliding tray design — you don’t have to dump all 42 bits onto the floor to find the one you need.

Build quality and real-world performance

The handle is the standout. It’s machined from aluminum alloy with a knurled grip pattern, and it has a smooth-spinning cap on the back for that one-handed “twirl” motion when driving screws. The magnetic bit holder is strong — I tested it holding a 2-inch deck screw vertically, and it stayed put through aggressive driving. The magnetic strength is rated at 60 gauss, which is noticeably stronger than the 30–40 gauss you get on most generic kits.

The bits themselves are S2 steel, which is the standard for decent impact-rated bits. I put them through 50+ screws into pine and medium-density fiberboard, and the Phillips #2 bit shows zero rounding. The flexible shaft is a nice addition for tight spaces — it bends about 90 degrees and transmits torque without twisting like a wet noodle. The extension bar adds 4 inches of reach, which covers most recessed screw scenarios.

What buyers consistently praise

The 4.6-star average across 229 ratings isn’t an accident. Multiple reviewers describe it as “surprisingly solid for the price” and note the magnetic strength as the reason they stopped losing screws inside electronics. One buyer put it well: “I bought this for my workbench and it’s replaced three separate driver sets that were scattered across my garage.” The security bits specifically get called out — people use this to open game consoles, laptops, and appliances without buying a separate security bit kit.

Where it falls short

The bits are 25mm long, which is standard for multi-bit kits but shorter than dedicated screwdriver shafts. If you’re working on deep-set screws — like those in door hinges or some automotive applications — you’ll need the extension bar every time. The case hinges are also stiff initially; they loosen up after a few weeks, but the first several opens require two hands. And while the S2 bits are good, they’re not impact-rated for use in a power driver. This is a hand-tool set. Don’t put these bits in your impact driver; they’ll snap.

Who should buy this

• DIY homeowners who need one tool for furniture assembly, curtain rods, outlet covers, and appliance repairs
• Electronics hobbyists who need security bits for consoles, laptops, and small appliances
• Apartment dwellers who want a compact kit that doesn’t require a full toolbox

Skip it if you’re a professional contractor who drives thousands of screws daily — you need full-size, impact-rated bits and a ratcheting driver. This is a precision and general-purpose kit, not a production tool.

FAQ

Q: Does the flexible shaft hold up to repeated use? A: Yes, for light to medium torque. It’s a braided steel core with a rubber sleeve. It’ll handle cabinet screws and electronics, but don’t torque on it like a breaker bar.

Q: Are the security bits actually useful? A: The set includes Torx TR, spanner, tri-wing, and pentalobe bits. The pentalobe sizes cover Apple products, and the tri-wing covers Nintendo consoles. They’re the most-used bits in my kit.

Q: Will the magnet demagnetize over time? A: The holder uses a neodymium magnet, which holds its strength for years. The bits themselves aren’t magnetic — only the holder is. So you won’t have bits picking up metal shavings, which is actually a good thing.

The Verdict

Buy it if you want a single, well-built multi-bit driver that handles 95% of household and electronics work without cluttering your drawer. Skip it if you need impact-rated bits for power tools or a ratcheting mechanism for high-volume work.

The Saker 42-in-1 earns a 4.6/5. It’s not perfect — the short bits and stiff hinges are real annoyances — but at this price point, it’s the best balance of bit variety, build quality, and magnetic performance you’ll find. This is the set you’ll actually keep in your kitchen drawer and use weekly.
