GURADESIGNTorx Bits Set,36PCS Tamper Resistant Star Bits Set,Security Torx Bit Set, T5 - T40, S2 Steel, 1" and 2.38" Long

I do a lot of handyman projects. We recently moved into a new place, and one of the items here was an old pergola that had some rotting wood. It might have been salvageable. Instead, we decided to remove it. I found while starting the removal that most of the fasteners were torx of some size. It had many T25s, a few T30s, and some of the larger lumber was affixed with T40s. This set had them all. Some of the bolts were torx-fitted sleeves, so I needed a bit on both sides. This set had multiple bits, so I had all of the bits I needed.Note that this set is tamper-proof which means the torx bit has a hole in the middle. You'd think that would make the bit less sound, but these bits held up as well as "normal" torx bits could be expected to.The pergola had been up about 15 years or so. Most of the bolts - there were also some hex bolts and philips - were rusted, but not all of them. I used these bits to remove as many as I could, which was probably 95%+ of them. Some of the torx bolts stripped anyway, but none of the bits showed any significant damage.These bits are as good as any I own, and better than many that I own. These are worth the price. If you need tamper-proof or even non-tamper-proof torx bits, these are a good buy.

Lo use una vez y la punta que estaba usando no aguanto el primer trabajo, se rompió 😩

I build E-scooters for a living and every bolt on them is a tamper resistant torx head bolt. Unfortunately, my company doesn't have enough tools to go around at the moment but they're working on it. However logistics can be slow so I decided to get my own set of tools. So far I have built over 100 scooters to date. That's a total of nearly 4,000 screws torqued with these bits up to 11 newton meters. Not one of them broken or worn down. These are high quality bits and compared to others this was the better value. They're also way easier to use than philips, hex, or flat head screws.

Except for the minor hiccup with the initial shipment not having the 60mm T25 or T8 bits but rather in their spots were an extra T9s and T10sEverything about these bits have been great with no noticeable wear after heavy use disassemblying my 8 year old rather large raised garden/greenhouse.Good price for what you receive, hiccup was quickly handled. I would definitely buy these bits again

Half the problem with bits is that they're hard to keep organized. These bits are nice, but I wish the case they came in was more functional. It should open easy, close securely and make taking bits in/out easy. It should also be clearly marked with the bit type. The orange part of these bits is just a sticker, which seems weird.
