Description
Ten essential drill sizes in one set. The Proxxon HSS twist drill set covers the ten most useful small-diameter sizes from 0.3mm to 3.2mm — spanning wire gauge sizes #80 through #30 — for drilling in steel, sheet metal, cast iron, non-ferrous metals, wood, and plastics with Micromot rotary tools and drill stands. HSS (High Speed Steel) construction delivers the hardness and heat resistance needed for clean, accurate holes across a wide range of materials.

Frequently Asked Questions
What rotary tools are these compatible with?
These drills are compatible with any Micromot tool that accepts the appropriate collet size, including the IBS/E and IBS/A. For precise vertical drilling, pair with the MB 200 Drill Stand.
Are these standard wire gauge sizes?
Yes — the set uses standard US wire gauge (AWG) drill numbering (#80 through #30), with metric equivalents listed for each size. Both systems are widely used in precision machining and electronics.
What's the smallest drill in the set?
The smallest is #80 at 0.3mm — suitable for very fine pilot holes in PCBs, jewelry, and precision model components.
