Best for

Model makers, jewelers and electronics hobbyists who need tiny holes.

Things to consider

  • Bits this small break easily, so use a pin vise or a rotary tool at low speed and keep the drill straight rather than pushing hard.
  • The shank size is not stated, so check that the shanks suit your pin vise or chuck, because many micro bits have a 1/8 inch or 2.35 mm shank.
  • Delivery from overseas takes roughly one to three weeks, and the 93.8% positive feedback is a little lower than average, so check recent comments.

Skip it for anything safety-critical, brand-name or urgent. Check the seller's feedback score, the delivery estimate and the import-charge line at checkout before you pay.
