What is a 5m tattoo needle used for?

Answer 1

I assume you're referring to a 5 Magnum needle configuration. 5 Mag's are used for shading and coloring or "filling in". It is a very versatile configuration that also allows a lining ability it the machine is held at the proper angle. Basically, the configuration is 3 needles across the bottom and two needles stacked on top of those.

We use them all of the time at our shop and they work well but will take some practice for someone new to the technique.

Color with a small circular pattern to fill in areas.
