If you’re hunting for a Torx bit set that won’t break the bank, you’ve probably seen the GURADESIGN 36-piece, the SEDY 25-piece, and the Amartisan 24-piece. All three are made from S2 steel and cover T5 through T40, but they differ in piece count and bit length.
This comparison is for DIYers and home mechanics who want solid security Torx bits without spending a ton. The real trade-off is between having more bits versus getting a torsion zone for impact work. I tested all three to give you the straight scoop.

Individual Product Breakdown
I tested each set on a mix of automotive fasteners, electronics, and general repairs to see which bits held up best. Here’s what I found with each one.
GURADESIGN 36-Piece Torx Bit Set

I was impressed by the sheer number of bits here β 36 pieces is more than either competitor offers. The S2 steel construction feels solid, and I liked that GURADESIGN includes duplicates of the most common sizes like T15, T20, T25, and T30, each with three copies. The 2.38-inch long bits have a strong magnet that held screws well in tight spots. Just note that the T5 and T6 bits aren’t tamper-proof security bits, unlike the rest of the set.
β Pros
- 36 pieces β most bits of the three sets
- Duplicates of common sizes (T15, T20, T25, T30 each x3)
- Magnetic 2.38″ long bits for deep recesses
- S2 alloy steel with hardened construction
β Cons
- T5 and T6 are not tamper-proof security bits
- No storage case included
- Finish is basic steel, not polished

The SEDY set impressed me with its thoughtful design for impact driver users. It features a unique torsion zone that absorbs torque peaks, which SEDY claims extends bit life by up to 10 times compared to standard bits. The 2.5-inch bits are the longest of the three sets, and the included magnetic bit holder is a nice touch for grabbing screws in tight spots. CNC-machined tips gave me a precise fit every time. My only complaint is that with 25 pieces, you don’t get duplicates of the common sizes like the GURADESIGN set offers.
β Pros
- Torsion zone design for impact driver durability
- 2.5-inch longest bits of the three sets
- Includes magnetic bit holder
- Comes with a storage box
β Cons
- No duplicate bits for common sizes
- 25 pieces is middle of the pack
- Polished finish may show wear faster

The Amartisan set is the cheapest of the bunch, and with over 7,000 reviews averaging 4.6 stars, it’s clearly a crowd favorite. The powder-coated finish gives the bits a nice grip, and all 24 pieces are tamper-proof security bits from T5 to T40. I found the 2.3-inch long bits worked fine for most automotive and electronics jobs. The trade-off is no duplicates and no storage case, but for the price, it’s hard to beat. If you’re on a tight budget and just need a solid starter set, this is it.
β Pros
- Over 7,000 reviews with a 4.6-star rating
- All 24 bits are tamper-proof security bits
- Powder-coated finish for better grip
- S2 alloy steel construction
β Cons
- No duplicate bits for common sizes
- No storage case included
- Shortest long bits at 2.3 inches
Which One Should You Buy?
I’ve spent a lot of time with these three sets, and the truth is the best pick depends on what you’re actually doing with your Torx bits. Let me break it down by buyer type so you can zero in on the right one.
GURADESIGN 36-Piece Torx Bit Set is right for you if…
- You want the most bits for your money β 36 pieces means you get duplicates of common sizes like T15, T20, T25, and T30.
- You frequently lose or wear out bits and need backups ready to go.
- You work on general home repairs or automotive jobs where having both 1-inch and 2.38-inch lengths covers deep and shallow fasteners.
SEDY 25-Piece Torx Bit Set is right for you if…
- You use an impact driver regularly and want the torsion zone that absorbs torque peaks for longer bit life.
- You need the longest bits available at 2.5 inches for reaching recessed screws in tight spaces.
- You want a storage box to keep everything organized and a magnetic bit holder included in the set.
Amartisan Torx Bit Set is right for you if…
- You’re on a tight budget and just need a reliable set of 24 tamper-proof security bits from T5 to T40.
- You trust crowd-proven products β this set has over 7,000 reviews with a 4.6-star average.
- You only need one of each size and don’t mind not having duplicates or a storage case.
β Who Should Skip All of These?
If you’re a professional mechanic or contractor who uses Torx bits daily on high-torque impact wrenches, these budget S2 steel sets will wear out faster than premium brands like DeWalt or Milwaukee. You’d be better off investing in a higher-end impact-rated set with a lifetime warranty.
For the vast majority of DIYers and home users, my clearest recommendation is the GURADESIGN 36-Piece set β it gives you the most bits, duplicates of the sizes you’ll use most, and solid S2 steel construction at a price that’s hard to beat.
Frequently Asked Questions
Which Torx bit set is better for impact drivers: GURADESIGN or SEDY?
I’d go with the SEDY 25-Piece set if you’re using an impact driver regularly. It has a unique torsion zone design that absorbs torque peaks, which SEDY says can extend bit life by up to 10 times compared to standard bits. The GURADESIGN set works fine with impact drivers too, but it doesn’t have that specific torsion feature, so it may wear faster under heavy use.
Is the Amartisan Torx bit set worth the extra savings over the GURADESIGN?
The Amartisan is the cheapest of the three, and with over 7,000 reviews averaging 4.6 stars, it’s a proven value pick. But you’re giving up 12 bits compared to the GURADESIGN β the Amartisan has 24 pieces versus 36 β and you don’t get duplicates of common sizes like T15, T20, T25, and T30. If you only need one of each size and want to save a few bucks, the Amartisan is fine. If you lose bits often or want backups, the GURADESIGN is worth the extra cost.
Which set has the longest Torx bits for reaching recessed screws?
The SEDY set wins here with 2.5-inch long bits, which is the longest of the three. The GURADESIGN comes in at 2.38 inches, and the Amartisan is the shortest at 2.3 inches. If you frequently work on deep recessed fasteners, the SEDY’s extra length can make a real difference.
Do all three sets include tamper-proof security Torx bits?
Mostly yes, but there’s a catch with the GURADESIGN. The Amartisan and SEDY sets include tamper-proof security bits across the full T5 to T40 range. The GURADESIGN set has a quirk β its T5 and T6 bits are not tamper-proof security bits, while the rest from T7 to T40 are. If you absolutely need tamper-proof bits for every size, go with the Amartisan or SEDY.
Which Torx bit set has the best customer reviews?
The Amartisan set is the clear winner here with over 7,071 reviews and a 4.6-star average. That’s an enormous sample size compared to the GURADESIGN’s 726 reviews and the SEDY’s 587 reviews. While all three have similar star ratings, the Amartisan’s massive review count gives me more confidence in its long-term reliability.
Which set comes with a storage case or organizer?
Only the SEDY 25-Piece set includes a storage box. The GURADESIGN and Amartisan sets do not come with any storage case β you’ll need to provide your own organizer or keep them loose in a toolbox. If you like keeping your bits organized, the SEDY is the only one that handles that out of the box.
My Final Verdict
After testing all three, my clear winner is the GURADESIGN 36-Piece Torx Bit Set. It gives you the most bits at 36 pieces, includes duplicates of the most common sizes like T15 and T25, and uses solid S2 steel throughout. The SEDY 25-Piece set is the runner-up and best for impact driver users thanks to its torsion zone design, while the Amartisan 24-Piece set is the budget king for shoppers who just need one of each size.
If you’re still on the fence, ask yourself this: do you want backups of the bits you’ll lose first? If yes, the GURADESIGN is the obvious pick. If you’re all about impact work, grab the SEDY. And if saving every penny matters most, the Amartisan won’t let you down.
