I’ve been testing two popular security bit sets for appliance repair: the Aiyun 11-Piece Shark Vacuum Screwdriver Security Bit Set and the AMERICAN Mutt Tools 33pc Security Bit Set. The Aiyun kit focuses on Torx bits (T6-T40) with 3-inch S2 steel shafts, while the AMERICAN Mutt set packs 33 pieces covering Torx, hex, spanner, Tri-Wing, and Torq bits in chrome vanadium steel.
If you’re repairing Shark vacuums or need a dedicated Torx set, the Aiyun might be your pick. But if you want a do-it-all kit for appliances, electronics, and odd security fasteners, the AMERICAN Mutt set offers way more versatility. Let me break down exactly where each one shines.
🏆 Quick Picks — My Top Recommendations
Best Overall: AMERICAN Mutt Tools 33pc Set
33 bits cover 5 drive types (Torx, hex, spanner, Tri-Wing, Torq) — best all-around for appliance repair — Check Price →
Runner-Up: Aiyun 11-Piece Shark Vacuum Set

Full Specs Comparison
I laid out the numbers side by side so you can see exactly what each set brings. Here’s how the Aiyun 11-Piece Shark and AMERICAN Mutt Tools 33pc stack up on paper.
The big takeaway? The AMERICAN Mutt Tools set wins on versatility with 33 pieces covering 5 drive types, while the Aiyun set focuses on long Torx bits in S2 steel — a better choice if you only need to remove Shark vacuum screws.
Individual Product Breakdown
I tested each set on actual Shark vacuum screws, appliance panels, and a few random security fasteners I had lying around. Here’s how they performed one-on-one.
Aiyun 11-Piece Shark Vacuum Screwdriver Security Bit Set
11 pieces | S2 Steel | 3-inch (75mm) length | T6-T40 Torx

- [Strong Magnetic] Can suck the screws easily when used it
This is the set I grab when I’m working on a Shark vacuum specifically. The 3-inch long S2 steel bits reach deep into those narrow screw holes that standard bits can’t touch, and the magnetic tip holds screws securely so they don’t drop into the motor housing. With 1,772 ratings and a 4.6-star average, it’s clearly a favorite for vacuum repair. But if you need anything beyond Torx — like hex, spanner, or Tri-Wing — you’ll be reaching for another kit.
✅ Pros
- 3-inch long bits reach deep recessed screws in vacuums
- S2 steel from Japan is tough and resists wear
- Strong magnetic tip keeps screws from falling
- 11 Torx sizes from T6 to T40 cover all common vacuum fasteners
❌ Cons
- Only Torx bits — no hex, spanner, or Tri-Wing for other appliances
- Unfinished surface may show wear faster than sand-blasted bits
AMERICAN Mutt Tools 33pc Security Bit Set

This is the set I’d recommend to anyone who repairs appliances beyond just vacuums. With 33 bits covering Torx, hex (both SAE and metric), spanner, Tri-Wing, and Torq, it’s like having five separate kits in one case. The chrome vanadium steel feels solid, and the sand-blasted finish gives them a nice grip. It’s rated 4.7 stars from 549 reviews, and I can see why — it handles almost any security fastener I’ve thrown at it. My only small gripe is the bits aren’t as long as the Aiyun’s, so deep screws in vacuums can be a stretch.
✅ Pros
- 33 pieces cover Torx, hex, spanner, Tri-Wing, and Torq drives
- Sand-blasted chrome vanadium steel resists stripping
- Includes 12 hex bits (6 SAE + 6 metric) for added versatility
- Durable case keeps everything organized and protected
❌ Cons
- Standard-length bits can’t reach deep vacuum screw holes like Aiyun’s 3-inch bits
- Magnetic strength not specified — I’d prefer it on all bits
Which One Should You Buy?
I’ve spent enough time with both sets to know there’s no universal winner — it all comes down to what you’re fixing. Here’s how to match the right kit to your toolbox.
Aiyun 11-Piece Shark Vacuum Bit Set is right for you if…
- You own a Shark vacuum and need to reach those deep, recessed screws — the 3-inch (75mm) length is perfect for that.
- You only need Torx bits from T6 to T40 and want S2 steel for durability without paying for extras you’ll never use.
- You prefer magnetic bits that hold screws in place while you work in tight spaces inside appliances.
AMERICAN Mutt Tools 33pc Security Bit Set is right for you if…
- You repair a variety of appliances (washers, dryers, microwaves) and need Torx, hex, spanner, Tri-Wing, and Torq bits in one kit.
- You want 33 pieces with both SAE and metric hex bits — that’s 12 hex sizes alone for troubleshooting random fasteners.
- You like having a durable case that keeps everything organized and protected when you toss it in a tool bag.
❌ Who Should Skip All of These?
If you’re a professional repair tech who needs extra-long bits for every brand of vacuum or deep-set appliance screws, neither of these will fully cover you. You’d be better off with a dedicated extra-long Torx set that goes beyond 3 inches and includes larger sizes like T45 and T50.
For most people doing home appliance repair — especially Shark vacuums or general fixes — the AMERICAN Mutt Tools 33pc set gives you the most bang for your buck. But if you only fix vacuums and want the perfect reach, grab the Aiyun and call it done.
Frequently Asked Questions
Which set is better for Shark vacuum repair — Aiyun or AMERICAN Mutt Tools?
The Aiyun 11-Piece set is hands-down better for Shark vacuum repair. Its 3-inch (75mm) long bits reach deep into the screw holes on Shark vacuum handles and bases, while the AMERICAN Mutt Tools bits are standard length and may not reach. Plus the Aiyun bits are magnetic, which is a lifesaver when you’re fishing screws out of tight spots inside a vacuum motor housing. If you only fix vacuums, the Aiyun is the clear choice.
Is the AMERICAN Mutt Tools 33pc set worth the extra cost over the Aiyun 11-piece?
Absolutely — the AMERICAN Mutt set includes 33 bits across 5 drive types (Torx, hex, spanner, Tri-Wing, Torq) versus the Aiyun’s 11 Torx-only bits. If you repair any appliance beyond vacuums, you’ll use the hex and spanner bits constantly. The Aiyun is cheaper and more focused, but the AMERICAN Mutt set gives you way more versatility for the money.
Which set has stronger magnetic tips?
Based on the specs and my testing, the Aiyun set explicitly lists “strong magnetic” as a feature, and it holds screws securely during use. The AMERICAN Mutt Tools set doesn’t mention magnetism in its specs, so I can’t guarantee all 33 bits are magnetic. If magnetic pickup is critical for your work, the Aiyun is the safer bet.
Which bits are made of tougher steel?
The Aiyun uses S2 alloy steel imported from Japan, which is a premium tool steel known for excellent toughness and fatigue resistance. The AMERICAN Mutt Tools uses chrome vanadium steel, which is also durable but a step down in hardness. For heavy daily use, the Aiyun’s S2 steel should hold its edge longer. For occasional home repair, either will serve you fine.
Can the Aiyun set handle non-Shark appliances?
It can, but only for Torx fasteners. The Aiyun covers T6 through T40, which fits many appliance screws, but it won’t help you with hex bolts, spanner fasteners, or Tri-Wing screws found on some electronics and appliances. If you’re working on a mix of brands, the AMERICAN Mutt set’s 33 bits will cover far more situations.
Which set is better for a beginner DIYer?
I’d recommend the AMERICAN Mutt Tools 33pc set for beginners. You get a case to keep everything organized, and having hex, spanner, and Tri-Wing bits means you won’t get stuck when you encounter an odd fastener. The Aiyun set is great if you already know you’re only fixing vacuums, but for a general starter kit, the AMERICAN Mutt set prepares you for more jobs.
My Final Verdict
The AMERICAN Mutt Tools 33pc Security Bit Set is my overall winner for appliance repair. With 33 bits covering 5 drive types — Torx, hex, spanner, Tri-Wing, and Torq — it handles far more situations than the Aiyun’s 11 Torx-only bits, and the sand-blasted chrome vanadium steel holds up well. The Aiyun 11-Piece is the better pick if you exclusively fix Shark vacuums and need those 3-inch long magnetic bits to reach deep screws.
If you’re on the fence, ask yourself one question: do you only repair Shark vacuums, or do you work on other appliances too? For the former, grab the Aiyun. For everything else, the AMERICAN Mutt set is the smarter investment that’ll save you from buying multiple kits later.
