  • Size - Drilling diameter: 1.45mm (0.0571"); round shank diameter: 3.175mm (1/8"); drilling depth: 12mm (0.472"); total length: 38mm (1.5").
  • Material - Micro drill bit set for PCB is constructed of Tungsten steel material, featuring high hardness, high strength, heat resistance, resistance to deformation, and ensuring long-lasting performance. The smooth chip discharge also reduces friction, ensuring faster drilling processes.
  • Features - Precision-honed cutting edges diminish required cutting force, thereby decreasing drill failure incidents and enhancing the overall integrity of the drilled hole. The meticulous symmetry of these edges is great for promoting cutting actions and avoiding any lateral displacement during the drilling process.
  • Applications - Tungsten steel Carbide drill bit set is specifically designed for PCB, CNC engraving and other high-precision hole required equipment, suitable for electronic boards, SMT, amber, hardware and other precision parts of the drilling process.
  • Note - Ensure the drill bit with spiral flute is appropriate for the material you're drilling into. Apply lubricant, such as cutting oil or coolant, especially when drilling metal which reduces friction, heat, and prolongs the bit's life.
