ottime punte !!! robuste in un pratico contenitore di plastica
Exactly what was looking for. Set of very small drill bits perfect for drilling into PCBs and making Jewelry and small projects. The bits are sharp and stay centered in the drill/rotary tool. Have tried in both a 3/8" chuck and a Smaller Rotary tool without any issues. Size is printed on shaft of bit. Bits are fragile so go slow and careful when drilling!
