鑽頭組，19件公制標準長度高速鋼

Needed a precise set for small electronics work, and the fact that it includes every half-millimeter from 1 to 10 mm covers everything I use. The high-speed steel cut clean through aluminum without any binding.

I was drilling through some mild steel today and these bits cut cleanly without any binding. The 0.5 mm increments between sizes are exactly what I needed for precise work.

The Huot case keeps everything organized, and having sizes from 1.0mm up to 10.0mm in 0.5mm steps means I rarely need to hunt for the right bit.
