These PCB drill bits are 1.0mm solid tungsten carbide micro drills for clean, accurate through-holes in printed circuit boards. The 10-pack uses the standard 1/8 in (3.175mm) shank found on PCB drilling machines and desktop CNC routers.

1.0mm is a common hole size for through-hole component leads, pin headers and connectors. Carbide stays sharp in abrasive glass-fiber board, but it is brittle: run the bits in a drill press, CNC or PCB drill stand rather than freehand.

Specifications

  • Type: carbide PCB micro drill bit
  • Drill diameter: 1.0mm
  • Shank: 1/8 in (3.175mm)
  • Cutting length: 9mm
  • Overall length: 38mm
  • Material: solid tungsten carbide
  • Pack: 10 drill bits
  • Materials: FR-4, CEM-3 and other circuit board laminates, plastics and composites

Compatibility

Fits CNC router collets, PCB drilling machines and rotary tools that take a 1/8 in (3.175mm) shank.

FAQ

Can I use these in a handheld drill?
Not recommended. Side load from a handheld drill snaps carbide micro drills. Use a drill press, CNC or a rotary tool in a drill stand.

What spindle speed should I use?
Carbide micro drills work best at high speed with a slow, steady feed. Follow your machine's guidance for 1mm bits in FR-4.
