10PCS Torx Head Screwdriver Bit Set, VAKOGAL S2 Steel Magnetic Security Tamper Proof Star 6 Point Screw Driver Kit Tools, 1/4 Inch, Hex Shank T7-T40

These are Torx bits which have a shank so you can chuck them into your drill or similar driver. The usual bits have about 1/4" shoulder to fit into an adaptor which you then use in your drill or manual driver. When you use them if you get a little bit of cant the bit falls out. These bits do not fall out since they be secure in your drill chuck. My only complaint is why did it take so long for someone to create this easy fix? It is a pleasant surprise to find a fix for a too common problem.

Good purchase. A must have for the 'not-so-common' Torx.

Works as advertised. Medium quality but good for the average person.

So far goodbye for your money

The bit sizes are engrave on the side of each bit, but the text can be hard to read. I needed to disassemble a the rotating head assembly on a Shark vacuum cleaner, which requires several different sized Torx security bits. So this kit fit the bill. I did not observe any wear on these bits after use. The magnetic strength of these bits is not that strong, but it was not a significant issue.

If you own an out-of-warranty Mercedes Benz, you need these. This set comes with all the sizes you'll need to perform any repairs in your Mercedes, because they use hex head screws a lot! The set is very well-priced, and seems to be very durable.

Strong and good variety of sizes, sturdy and fits great

When you need a certain size screw driver bit, nothing else will do. These are excellent bits and in a full size range. I never hesitate when purchasing tools. They will last forever and as long as I keep them all in their tight grip holder, they will be at my ready, when I need them. I hate starting a project only to find I don't have a certain size tool I need. I can use them in a magnetic screw driver holder or in my electric drill/screw driver. I had a big project and they stood up well, show no wear and should last a lifetime.
