Precision Carbide Drill Basics (Applies to All Drills Below)

Originally designed for PCB fabrication, these precision carbide drills are widely used for micro-drilling in plastics, composites, thin metals, and other materials where accuracy and tool rigidity matter. Offered in both new and factory-resharpened options.

  • Solid Carbide Construction
    Designed for precision drilling in FR-4, G-10, phenolic, and other abrasive materials. Significantly harder and longer-lasting than HSS.
  • 1/8" Shank (3.175 mm)
    Industry-standard shank size compatible with most small CNC spindles, drill presses, and depth-stop systems.
  • 1.50" Overall Length
    Standard short-length design for consistent consistent tool stick-out (how far the drill extends from the holder) and predictable depth control.
  • Depth Stop Rings 
    Allow precise control of drilling depth and repeatability in manual and semi-automatic setups.
  • Size-Specific Cutting Diameter
    Shank size remains constant — only the cutting diameter changes.
