FK Irons One Adjust Tattoo Machine with Adjustable Stroke - Gunmetal

The FK One Adjust brings a groundbreaking upgrade to the FK One series: a patented rotary mechanism that, for the first time, allows the stroke length to be efficiently changed in 0.5 mm increments between 2.0 mm and 5.0 mm. It has never been easier to spontaneously adapt the machine to any situation – enabling tattoo artists to precisely execute any technique and style.

With a specially developed motor, this innovative machine sets new standards in adaptability and ease of use. The fixed-stroke cam is coupled to a paddle connection, while a rotating slider adjusts the stroke length by moving closer to or further from the center of the paddle. This reduces friction and wear, ensuring consistent, long-lasting performance in every session.

All the familiar features of the FK One are retained – but the FK One Adjust goes a step further, offering additional flexibility and precision. Whether you're an experienced artist with many years in the business or a beginner looking for a high-quality, versatile machine: this tattoo pen delivers smooth, controlled work at every level.

The FK One Adjust features an integrated digital display for real-time readings of volts or hertz, with a touchscreen interface that responds smoothly even with gloves, ensuring a clean and efficient workflow throughout the session. The machine can also be configured for both right- and left-handed users.

Designed for long-lasting durability, the precision-engineered motor delivers consistently strong performance. The machine also comes with two dual-rechargeable Panasonic batteries in a drop-in design. The 18500A short-cap battery (0.25" depth) provides up to 5.5 hours of runtime. The 18650A long-cap battery (0.75" depth) achieves up to 6.5 hours. Please note: Actual runtime may vary depending on voltage, stroke, and other operating parameters.

The newly designed anti-roll cap ensures the machine sits securely on your work surface, while the ergonomic shape reduces hand fatigue. For added comfort and hygiene, it is compatible with Ergo Shield disposable handles.
