A robust and reliable tattoo machine, typically constructed primarily of iron, is often favored for its durability and consistent performance. These machines are often chosen for lining and shading due to their power and stability. An example would be a classic coil machine built with a solid iron frame and core.
The sturdy construction of these machines makes them suitable for extended use and capable of handling various needle configurations. Their longevity contributes to a lower cost of ownership over time, and their consistent function allows artists to achieve predictable results. Historically, iron has been a prevalent material in tattoo machine construction, giving rise to the “workhorse” designation due to its dependable nature.
