12-Pack Torx Bit Set 3 inch, Impact Security Torx Bit Set (T5- TT40) Profession Torx Bits, Magnetic Star Bits Set, Tamper Proof Torx Bit Set Premium S2 Steel, Torx Bit 1/4'' Hex-Shank, Star Bits

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.

Work good built a room addition with them

Great set. Well worth the money. Made of strong metal so u won't have to worry about breaking tips i don't think.

very small, but they get the job done

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