This is a set of ground HSS (High Speed Steel) micro twist drill bits for drilling holes in metal, wood and plastics. There are 20 sizes in the set, 0.3mm - 1.60mm, all with a straight shank. The box allows you to dispense one drill at a time, keeping all others securely in place.

HSS or high Speed Steel can sustain high temperatures, is non-brittle and is therefore suitable for metals as well as wood and plastics. Ideal for drilling holes into driftwood for your coastal creations.
