Key specifications

Selecting the right option

Wire gauge numbering runs from #80 (0.343mm) to #1 (5.791mm) — the higher the number, the smaller the diameter. Tap drill charts for inch threads specify the correct wire gauge drill. These drills are used in engineering and toolmaking; for general trade work, fractional or metric drills are more practical.
