12-Pack Impact Security Torx Bit Set (T5-T40) 3-Inch Long, S2 Steel, Professional Tamper Proof Star Bits Set, with 1/4" Hex Shank, Magnetic & High Torque for Automotive/Electronics/DIY

I tear down a lot of power tool batteries for testing and quite often screws are deeply recessed, too far for a regular 1/4" bit to reach in holes too small for such bits and cordless screwdriver shafts. I got these bits for the exact purpose of reaching those specific torx screws. On the plus side is that these bits also have the center hole so they work for "security" torx screws as well. I've been using this set for about a week now, mostly just the T10 size, and I'm very happy with their performance so far. The bits still look new. The included storage strip has held up well also, it holds the bits but not so tightly that they're hard to remove when you need them.

These are great. Even the smaller sizes are hard enough to withstand the pressure of turning a stubborn bolt.

Super nice quality didn’t strip any of my ps4 bolts and the magnetic strength came in clutch a lot and if you thing it’s week we used one to unscrew a rusted bolt with a impact and after a minute if letting it eat the bolt finely let go

Nice quality

These stupid "security screws" are a curse and a huge inconvenience! This is the cheapest and most effective way to deal with them.

I have many Torx bits, but all required a bit driver to fit a deep narrow hole. My bit drivers were too wide. This 12-pack had the sizes, longer bit length, and shaft width I needed for my application.

Just what I needed, hard to find at local stores, also good price.

Great set , had to take apart my hedge trimmer to sharpen . Needed to take it apart . Worked great .
