Magnetic PH2 Screwdriver Bits for $1.64 — Worth It?

The bit that keeps slipping out of your screw head

If you've ever stripped a screw because a worn-out bit lost its grip, you know how frustrating it is. And if you've ever dropped a tiny screw into the gap behind a wall panel because your bit has no magnet, you really know. These are small irritations that add up fast on any DIY project.

I came across this set of magnetic PH2 screwdriver bits from Deli while looking for a budget replacement after my last set gave out. The price — $1.64 after a 64% discount — made me skeptical. That's less than a cup of coffee for a multi-length bit set. I dug into the reviews and specs to figure out if this was actually worth ordering.

What you actually get

The set includes bits in lengths of 25, 50, 65, 70, 90, and 150 mm — a wider range than most budget sets, which typically stop at 50 mm. The longer 150 mm bit alone is useful for recessed screws or tight angles that a short bit can't reach.

The material is S2 hardened steel. This matters more than most people realize. S2 is a tool steel with higher torsional strength than the generic chrome-vanadium steel in cheap sets — it resists deforming at the tip under load, which is exactly what causes cam-out and stripped screws over time. Multiple reviewers across different countries mentioned the bits held up well after weeks of regular use, which is consistent with what you'd expect from S2 steel at this price point.

The magnetic grip is genuinely functional. One reviewer from the UK noted they only had to replace the head after a few weeks of use — not days — which suggests the magnet isn't just decorative. When you're driving screws overhead or in a tight cabinet, a magnet that actually holds is the difference between a five-minute job and a twenty-minute one.

The anti-slip design on the shank helps with manual grip when you're not using a drill.

The honest limitations

These are not impact-rated bits. If you're running a high-torque impact driver all day on a construction site, these will not hold up the way dedicated impact bits would. The internal structure of impact bits is specifically designed to absorb sudden torque spikes — standard bits, even good ones, are not built for that.

Also worth noting: quality control on AliExpress orders can vary. The vast majority of reviews are positive, but with a budget product from a Chinese manufacturer, occasional batch variation is a real possibility. For most people ordering one set for home use, this is unlikely to be an issue — but it's honest to mention it.

What else would $1.64 buy you?

At this price, in a hardware store, you're looking at a single generic bit — no material spec, no magnet, no length variety. On Amazon, a comparable multi-length magnetic bit set from a recognizable brand runs $8 to $15. That's five to ten times the price for a product that, in everyday home use, will perform similarly.

What surprised me when I looked at competing AliExpress listings in the same price range is that most don't specify S2 steel — they just say "chrome steel" or give no spec at all. The Deli branding here and the explicit S2 specification gives this set a credibility edge over anonymous alternatives.

The 10,000+ orders and 4.8 rating across that volume is also a genuine signal — not a handful of inflated reviews, but consistent feedback from a large number of buyers.

Buy it if / Skip it if

Buy it if:

• You do regular home DIY, furniture assembly, or light electrical work
• You want multiple bit lengths without paying for a full kit
• You need a backup set to keep in a toolbox or car
• Your current bits are worn and you want a cheap, decent replacement

Skip it if:

• You're using a high-torque impact driver professionally
• You need bits rated for construction or heavy-duty daily use
• You require a warranty or brand support for professional work

My honest take: this is a straightforward product that does what it says. The S2 steel is real, the magnet works, and the range of lengths is genuinely useful. It's not a professional-grade set and it doesn't pretend to be. For the price, the value-to-risk ratio is about as low as it gets.

If you go through bits regularly or just want a functional backup set, this is the most sensible option I found at this price.
