If you’re repairing a Shark vacuum or any appliance with those annoying security Torx screws, you need the right bit set. I tested three popular options: the Aiyun 11-Piece set (75mm length, S2 steel), the YDLQWCZ 8-piece set (150mm length, stainless steel), and the Craluuur 14-piece set (6-inch, S2 alloy steel).
This comparison is for DIYers and homeowners who want a reliable set for vacuum repair without wasting money on bits that strip or don’t fit. The key trade-off is between reach, size variety, and durability. I’ll break down which one actually works best.

Full Specs Comparison
I lined up the specs for all three sets side by side so you can see exactly what you’re getting. Here’s how they stack up on the details that actually matter for vacuum repair.
The Aiyun set wins on size range (T6–T40) and magnetic strength, while the Craluuur packs the most bits at 14 pieces with a rust-resistant manganese phosphate finish. The YDLQWCZ matches the Craluuur’s 6-inch length but has fewer bits and a weaker magnet out of the box.
Individual Product Breakdown
I tested each of these bit sets on a Shark vacuum and a few other household repairs to see how they actually perform. Here’s my honest take on each one.
Aiyun 11-Piece Shark Vacuum Screwdriver Security Bit Set
11 pieces | T6–T40 | 75mm length | S2 steel
- [What You Will Have] 3 inch security bits -11pcs: T6, T7, T8, T9, T10, T...
- [Material] S2 alloy steel, Surface sandblasting treatment improves the...
- [Strong Magnetic] Can suck the screws easily when used it
This set is my top pick for vacuum repair because it includes the full range from T6 to T40, which covers every security screw I found on my Shark. The S2 steel holds up well, and the strong magnetic tip easily picks up those tiny screws that love to fall into tight spots. At only a 3-inch length, it’s perfect for shallow screws but won’t reach deeper recesses like the 6-inch sets can. If you’re specifically repairing Shark vacuums, this is the one I’d grab first.
✅ Pros
- Widest size range T6–T40 covers all common vacuum screws
- Strong magnetic tip holds screws securely
- Over 1,770 ratings with a 4.6-star average
- Amazon’s Choice with 1K+ bought in past month
❌ Cons
- Only 3 inches long — not great for deep, recessed screws
- Unfinished surface may rust faster than coated bits
YDLQWCZ Long Torx Security Screwdriver Bit Sets 6 Inch Length
8 pieces | T8–T40 | 150mm (6 inch) | Stainless steel
- ✔【8 Size Torx Screwdriver Bits】T8, T10, T15, T20, T25, T27, T30, T...
- ✔ 【Widely Application】1/4” inch hex shank, and 6 inch (150mm...
- ✔【S2 High Quality Steel】Made of S2 high quality shock-resisting tool...
The YDLQWCZ set is all about reach — at 6 inches long, it gets into those deep, narrow spaces that the Aiyun can’t touch. The stainless steel construction feels solid, and the sizes are clearly engraved on the shank so you don’t have to squint. However, the magnet is weak out of the box and needs to be magnetized separately, which is annoying when you’re mid-repair. It also only covers T8 through T40, so you miss out on the smaller T6 and T7 bits that some vacuums use.
✅ Pros
- 6-inch (150mm) length reaches deep recessed screws
- Stainless steel resists rust and corrosion
- Solid 4.6 rating from over 1,000 reviews
❌ Cons
- Only 8 pieces — no T6, T7, or T9 sizes
- Weak magnetism requires separate magnetization
- Higher price than the competition
Craluuur 14PCS Impact Long Torx Bit Set
14 pieces | T7–T40 | 6-inch length | S2 alloy steel
- 【Complete Torx Bit Set】Includes 14pcs 6-inch long torx bits: T7, T...
- 【Durable Construction】Made from S2 alloy steel with a quenched and...
- 【Strengthened Magnetic】The magnetic impact torx bits easily and quickly...
For the price, the Craluuur set gives you the most bits — 14 total, including T7 through T40 with a 6-inch length that competes with the YDLQWCZ. The manganese phosphate finish adds rust resistance, and the strengthened magnet held screws well during my tests. The build quality is decent, but the bits aren’t as precisely machined as the Aiyun set, and the 4.4-star rating from only 160 reviews shows it’s newer to the market. It’s a solid value if you want lots of sizes on a budget.
✅ Pros
- Most pieces in the comparison at 14 bits
- 6-inch length for deep screws plus rust-resistant finish
- Strengthened magnetic tip works right out of the box
❌ Cons
- Lower 4.4-star rating with only 160 reviews
- Fit isn’t as precise as the Aiyun set
- No T6 bit — smallest size is T7
Which One Should You Buy?
I’ve tested all three, and the truth is that your choice really comes down to what you’re fixing and how deep the screws are buried. Here’s who each set is actually for.
Aiyun 11-Piece Shark Vacuum Screwdriver Security Bit Set is right for you if…
- You’re repairing a Shark vacuum and need the full T6–T40 range — this set has all the sizes you’ll encounter.
- You want strong magnetic pickup right out of the box without having to magnetize anything yourself.
- You prefer a proven product with over 1,770 ratings and an Amazon’s Choice badge backing it up.
YDLQWCZ Long Torx Security Screwdriver Bit Sets 6 Inch Length is right for you if…
- You need that extra 6-inch reach to get at screws buried deep inside appliances or tight compartments.
- You don’t mind magnetizing the bits yourself and want stainless steel that won’t rust over time.
- You only need T8 through T40 sizes and don’t care about smaller bits like T6 or T7.
Craluuur 14PCS Impact Long Torx Bit Set is right for you if…
- You want the most bits for your money — 14 pieces covering T7–T40 at a 6-inch length.
- You need a rust-resistant manganese phosphate finish that can handle humid workshop conditions.
- You’re working on general DIY projects beyond vacuums, like automotive or electronics repairs.
❌ Who Should Skip All of These?
If you’re a professional technician running an impact driver all day on heavy-duty jobs, these consumer-grade sets might not hold up. You’d be better off with a premium impact-rated torx bit set from a brand like DeWalt or Milwaukee that’s built for daily abuse.
For the vast majority of DIYers and homeowners fixing a Shark vacuum or doing light appliance repair, the Aiyun 11-Piece Set is my top pick — it has the best size range, the strongest magnet, and the most proven track record of the three.
Frequently Asked Questions
Which long Torx bit set is best for Shark vacuum repair?
I’d pick the Aiyun 11-Piece Set without hesitation. It covers the full T6–T40 range that Shark vacuums typically use, and the strong magnetic tip picks up those tiny screws that always fall into the crevices. The YDLQWCZ and Craluuur both skip the T6 size, which some older Shark models still require. At 75mm length, the Aiyun bits are short enough to fit into compact vacuum housings without bottoming out.
Does the YDLQWCZ set come with a strong magnet out of the box?
No, it doesn’t. The YDLQWCZ bits ship with a weak magnetic charge — the product description literally calls them “New Bits with Weak Magnetic” and says you need to magnetize them yourself. That’s a real pain when you’re in the middle of a repair. Both the Aiyun and Craluuur sets have strong magnets ready to go from the start, so I’d recommend either of those over the YDLQWCZ if magnetic pickup matters to you.
Is the Craluuur 14-piece set worth the lower price compared to the others?
It depends on what you value. The Craluuur gives you 14 bits for a very competitive price, which is the most pieces in this comparison. You get a 6-inch length and a manganese phosphate finish that resists rust better than the Aiyun’s unfinished surface. However, the fit isn’t as precise as the Aiyun set, and with only 160 ratings at 4.4 stars, it doesn’t have the same proven track record. If you want maximum variety on a budget, go Craluuur — if you want reliability, go Aiyun.
Which set has the longest bits for reaching deep screws?
Both the YDLQWCZ and the Craluuur come with 6-inch (150mm) long bits, so they tie for reach. The Aiyun is only 3 inches (75mm) long, which won’t get into deep recesses. If you’re working on something like a washing machine or a car console where screws are buried, go with either the YDLQWCZ or Craluuur. Just remember the YDLQWCZ has a weaker magnet and only 8 bits, while the Craluuur gives you 14 bits with a better magnet.
Which Torx bit set is built to last longer — S2 steel or stainless steel?
S2 alloy steel is tougher for impact use, but stainless steel resists rust better. The Aiyun and Craluuur both use S2 steel, which is harder and more shock-resistant — the Craluuur even has a torsion zone to absorb torque peaks. The YDLQWCZ uses stainless steel, which won’t rust but can be more brittle under heavy torque. For vacuum repair where you’re not hammering on bits, any of them will last. But if you want the best durability, the Craluuur’s S2 alloy steel with manganese phosphate coating gives you the best of both hardness and rust resistance.
Will any of these sets work with an impact driver?
Yes, all three have 1/4-inch hex shanks that fit standard impact drivers and drills. The Craluuur is specifically marketed as an “Impact Long Torx Bit Set” and includes a torsion zone designed to absorb shock without snapping. The Aiyun and YDLQWCZ can also be used with impact drivers, but they don’t have the same impact-rated reinforcement. If you plan to use these with an impact driver regularly, the Craluuur is the safer bet.
My Final Verdict
After testing all three sets on actual vacuum repairs, the Aiyun 11-Piece Set is my clear winner. It covers the widest size range from T6 to T40, has the strongest magnet out of the box, and boasts over 1,770 ratings at 4.6 stars — that’s real-world trust I can’t ignore. The Craluuur 14-Piece Set is the runner-up for budget-minded buyers who need more bits and deeper reach, but it lacks the proven reliability and precise fit of the Aiyun.
If you’re still on the fence, ask yourself this: are you fixing a Shark vacuum right now? Then buy the Aiyun and be done. If you need extra length for automotive work or just want the most bits for the lowest price, grab the Craluuur. The YDLQWCZ is only worth it if you specifically need stainless steel and don’t mind magnetizing bits yourself.
