📏 Wire Gauge Reference

Why Wire Gauge Reference Matters

Wire gauge sizes show up in machining more than you'd think — EDM wire selection, spring wire diameters, gage pins, and electrical wiring for machine tool installations all reference AWG or SWG sizes. This chart gives you the decimal diameter instantly.

• AWG numbers are inversely proportional to diameter — a lower gauge number means thicker wire (10 AWG is larger than 18 AWG)
• EDM wire is commonly 0.010 inch (brass) or 0.004-0.012 inch range — knowing the gauge helps when ordering or specifying
• Gage pins and plug gages follow similar sizing conventions — cross-reference with decimal equivalents for drill selection
