What Size Is a 7 Drill Bit in March?

What size is a 7 drill bit? It may seem like an easy question, but the answer can differ. Let’s look at the measurements and variations of size 7 drill bits.

Wire gauge sizes are used to size drill bits. Lower numbers mean larger diameters – so, a 7 drill bit has a diameter bigger than lower numbered bits. The size 7 drill bit usually measures 0.201 inches or 5.1 millimeters. This is standard for most drilling activities. However, measurements can differ across manufacturers and materials.

Drill bits have been used for centuries. Primitive versions were made with stones or bronze. As technology and metalworking improved, more precise and durable drill bits were created.
