Tattoo Machine
The device that drives the needle in and out of the skin to deposit ink. Main types: coil machines (electromagnetic), rotary machines (motor-driven), and pen-style rotary machines.
In detail
Coil machines produce a distinctive buzz and are preferred by many traditional tattooers for their tactile feedback. Rotary machines are quieter and more consistent — widely used in fine line and realism. Pen machines are ergonomic and popular for detail work. Machine type affects the feel of tattooing but doesn't determine quality.
