Fortex CBD3818/040 is a high-quality 0.4 mm solid carbide PCB drill bit designed for precise and repeatable circuit board drilling. Solid carbide ensures long tool life, clean holes and excellent dimensional accuracy even on multilayer and high-density FR4 boards.

The bit is fitted with a 3.17 mm (1/8”) standard shank, so it fits directly into most CNC and PCB drilling machines. An excellent choice for electronics manufacturing, prototyping and drilling very small through-holes.

Key features:

• Hole diameter: 0.4 mm
• Solid carbide
• Shank diameter: 3.17 mm (1/8”)
• Very precise and long-lasting
• Suitable for FR4 and multilayer PCB materials
