Mijia Rotary Tool Kit - Xiaomi

Yes, it is capable of engraving glass when using the appropriate diamond-tipped bits at a low-to-medium speed.

The Mijia Rotary Tool Kit is designed for portability, though you should check your specific regional variant for battery charging instructions.

It is best suited for light cutting of thin gauge sheet metal; it is not recommended for heavy structural metal work.

Verify that the collet nut is tightened securely and that the bit shank diameter matches the collet size.
