These 0.4mm PCB drill bits are solid tungsten carbide micro drills made for clean, accurate through-holes in printed circuit boards. Each box holds 10 identical bits, so you always have a sharp spare on hand for prototyping or small production runs.

Specifications

  • Drill diameter: 0.4mm (0.016 in)
  • Cutting length: 9mm; overall length: 38mm
  • Shank: 1/8 in (3.175mm), fits CNC routers, PCB drilling machines and rotary tool collets
  • Material: solid tungsten carbide with polished flutes for fast chip clearing
  • Symmetrical cutting edges help prevent drill wander
  • Materials: FR-4, CEM-3, carbon fiber, plastics and molds; also clears 3D printer nozzles
  • In the box: 10 bits

FAQ

Can I use these in a hand drill?
Carbide micro bits are hard but brittle. Use them in a CNC, drill press or rotary tool on a stand; side load from a handheld drill can snap a 0.4mm bit.

Do they fit a Dremel?
Yes, with the 1/8 in collet that comes with most rotary tools.
