A precision drill bit set from DSPIAE made from tungsten steel, covering sizes from 0.3mm to 1.2mm for fine detail work on plastic models, resin, and similar hobby materials. The tungsten steel construction provides greater hardness and durability compared to standard high-speed steel bits, helping maintain a sharp cutting edge through repeated use.
