Drill Bits Unlimited – Carbide Drill Basics

• Solid Carbide Construction
  Engineered for high-precision drilling in abrasive materials such as FR-4, G-10, and phenolic, while also being suitable for plastics, wood, composites, and non-ferrous metals when proper feeds, speeds, and handling are used. Significantly harder and longer-lasting than HSS.
• 1/8" Shank (3.175 mm)
  Industry-standard size compatible with most PCB drill presses, CNC spindles, rotary tools, and depth-stop systems.
• 1.50" Overall Length
  Standard precision length providing consistent tool stick-out and predictable depth control.
• Depth Stop Rings (When Included)
  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 between tools.
