Solid Carbide Micro Drills for Precision Machining

Explore BB Tool micro drills for small-diameter, precision hole machining. This collection brings together dedicated micro-drilling solutions for steel, aluminum, PCB and other precision applications, with multiple diameter ranges and shank configurations for CNC and precision drilling equipment.

  • Application-specific options: Choose dedicated micro drills for steel, aluminum, PCB and other precision machining applications.
  • Wide diameter selection: Small-diameter options are available across multiple product series for different hole sizes and machining requirements.
  • Multiple shank formats: Select from 3mm, 3.175mm and 4mm shank configurations depending on the product series.
  • Solid carbide construction: Designed for precision machining where rigidity, dimensional control and wear resistance are important.
  • Specialized configurations: The range includes standard micro drills, long-flute designs and internal-coolant options.

Choose by workpiece and application first. Steel and aluminum micro drills are separate product families and should be selected according to the material being machined. For very small diameters, use a stable machine setup, suitable toolholding and controlled cutting conditions.
