Jakemy UC02 Cordless Ultrasonic Cutter and Polisher is a 2-in-1 handheld tool using 40 kHz vibrations to cut, grind, and polish materials like 3D prints and PCBs quickly and cleanly.

• 40kHz Ultrasonic Cutting: True 40 kHz output delivers continuous high-frequency vibration, so cuts stay smooth and require less manual force, which speeds work on plastics, PCBs, and 3D print parts.
• Two Functions in One: A swappable holder lets you switch between blades and grinding sticks, so the same tool cuts then polishes without separate devices, reducing bench clutter and setup time.
• Three Modes and Feedback: OFF, ON, and AUTO modes fit short or long jobs; LED and buzzer confirm output and an auto-standby saves battery when left horizontal.
• Cooling and Replaceable Battery: Choose fanless or fan-cooled handles; the temperature probe and automatic fan keep run time stable while a replaceable 1000 mAh LiPo battery gives 45–60 minutes of working time.

UC02 fits hobbyists and small workshops needing precise, faster cutting and polishing; add blades, holders, or a benchtop rack.
