Torx 扳手，旗型，單一尺寸

The flag tip is a lifesaver when I’m swapping inserts on my turning tool holder—no more stripped screws from my own torque-happy hands. It fits snugly and the metal feels solid, not flimsy like a hex key. Definitely grabbing a few more sizes for the rest of my kit.

Used a few of these to swap out the inserts on my lathe tools and the flag shape really locks in your grip, no slipping. The cut is precise enough that they fit snug without stripping the tiny screws. Exactly what I needed for those finicky set screws.

The flag handle makes torquing these tiny screws in tight spots much easier than with a standard L-key. I bought a T15 to replace a stripped one in my boring bar set, and it fits perfectly without any wobble.
