The bits keep falling out while engraving. How do I install them securely?
Hold the bottom part of the chuck firmly while unscrewing the top cap. Insert the bit, continue holding the bottom part, and tighten the top cap securely. Never twist the top alone.
How do I turn the pen on and change the speeds?
Use light touches, no hard pressing! Long press the lower Power Button to start or close the pen. Single press the upper Gear Button to cycle through the 5 speeds (10,000-30,000 RPM).
Can this tool handle heavy-duty drilling on metal?
No. This mini tool is engineered for precision detailing, micro-engraving, and polishing. It is perfect for delicate tasks on jewelry, 3D prints, glass, and wood, but not for heavy grinding.
How long does the battery last, and how to charge?
Charge via the universal Type-C port. The TUV-certified 500mAh battery fully fast-charges in 80 mins, providing up to 2 hours of continuous crafting depending on speed and material.
Which bit should I use? Is it beginner-friendly?
Yes! It includes 30 CNC precision-machined bits. These versatile tips are perfect for etching glass, sanding 3D prints, wood carving, and polishing jewelry. Great for beginners out of the box!
