The Filter X30 is an adjustable-stroke wireless rotary built around a high-RPM coreless motor and one of the widest stroke ranges in its price class. Stroke adjusts from 2.0mm (PMU/fine detail) all the way to 4.2mm (heavy colour packing) on the machine itself — one tool, every technique. What 2.0–4.2mm stroke range covers: 2.0mm — PMU work (brows, lip blush, eyeliner), microblading combo, finest line 2.5–3.0mm — fine line tattoo, single-needle, SMP density 3.5mm — versatile middle for line + shade 3.8mm — confident lining, mid-density colour 4.0–4.2mm — bold lining, traditional colour packing, dense saturation Most adjustable-stroke machines max out at 4.0mm or top out at 5.0mm. The X30's 2.0mm low end makes it one of the few "single machine" options that genuinely covers PMU through tattoo work. 9500 RPM coreless motor. The coreless construction means no traditional iron core inside the motor, which delivers: Lower vibration during long sessions Smoother, more consistent torque under load Less internal heat buildup (better for marathon sessions) Longer motor service life 4-12V wide voltage range. Most wireless pens operate in 5-9V or 5-12V range. The X30 extends down to 4V, which gives you finer control on the soft end (gentle PMU, delicate shading) without compromising the upper end. Adjustable needle depth 0-4.5mm. Dial needle protrusion via the front housing — useful when switching cartridges or moving between line work and shading mid-session. Specs: Motor: Coreless brushless, 9500 RPM Stroke: 2.0–4.2mm (adjustable on machine) Voltage: 4–12V Needle depth: 0–4.5mm adjustable Weight: 242g (8.53oz) Dimensions: 146 × 36mm Body: Aircraft-grade aluminum Connection: Wireless Best for: Artists wanting one machine for both PMU and tattoo work Studios needing maximum stroke versatility Mixed-technique workflows (line + shade + pack in one session) Apprentices testing stroke preferences before specializing
