螺紋切削套件 — 7 件迷你螺絲攻與螺絲板組，1.2–1.6mm 金屬線螺紋加工

Finally got around to chasing a stuck thread on a vintage clock plate, and the 1.4mm die worked perfectly without chewing up the brass. The whole set fits neatly in my bench drawer, too.

For threading those tiny 1.2mm screw holes in model parts, these mini taps cut cleanly without binding. Each die is clearly marked, making it easy to pick the right size. The flat screw plate sits stable while you work, which saved my frustration.

Was fixing a tiny watch clasp and these mini dies cut the threads perfectly on the first try—the 1.2mm tap is exactly the right size for the job. The taps feel solid and the threading is surprisingly precise for such small pieces.
