The world's smallest and feather-light ultrasonic cutter weighs just 4.4oz (124g) without battery and 6.7oz (190g) with battery, making it lighter than any ultrasonic cutter. Power in your hand, freedom in your moves—cut anywhere, create everywhere. 40W auto power adjustment: intelligent control automatically adapts output for different materials, giving you smooth, precise cuts without overheating or stalling. 40kHz high ultrasonic vibration: the blade vibrates at ultra-high frequencies, creating micro-cuts that let you slice through materials like a hot knife through butter—perfect for ABS, PC, PLA, SLA resin, acrylics, wood, plywood, FDM prints, leather, cardboard, PCB, carbon fiber, clays, and more. Built-in turbo cooling for cleaner cuts: 13,000 RPM turbofan keeps the blade cool while you work, preventing heat buildup and ensuring every cut is smooth and precise. Dual exhaust vents balance airflow for equal comfort and performance, right- or left-handed. The gentle hum on startup is the fan at work. Includes 6 SK5 steel blades: standard, long, chisel, mini chisel, curved, and double edge. Lasts 2–3× longer than regular carbon steel, stays hard under heat, and features a rounded tip and magnetic quick-swap design for fast, safe change. True wireless and replaceable battery: twist and swap design for power on/off. 1300mAh pack fully charges in 30 mins and swaps in seconds. Pair with TurboDock (sold separately) for nonstop cutting—free from tangled wires. 2 cutting modes: press and hold for precision mode, perfect for trimming, deburring, fine-tuning, and detailing delicate parts. Toggle down for continuous mode, ideal for splitting, carving, grooving, and chiseling large projects. Wide application range: perfect for 3D printing support removal, DIY projects, household repairs, woodworking, prototyping, product design, model mods, garage kits, figurine processing, leather cutting, car modifications, jewelry making, and Gundam model building. Operation note: switch the battery to on; the fan will start automatically after 30 seconds, and the blade will heat up after about 1 minute of vibration — please do not touch. User notice: this ultrasonic cutter operates at 40kHz (vibration is not visible). The blade may become warm during use—do not touch the blade while operating.
