Description
The Proxxon GG 12 is a featherweight precision engraver that punches well above its size. At just 50g (under 2 oz) and spinning at 20,000 RPM, it delivers the fine motor control needed for detailed work in glass, metal, wood, and plastic — without the fatigue of a heavier rotary tool.

Power Requirements
The GG 12 requires a 12–18V DC power source — an AC adapter is not included. We recommend the Proxxon NG 2/S AC Adapter (No. 38706) for standard use, or the Proxxon NG 5/E with Electronic Speed Control (No. 38704) if you want variable speed control for different materials.
Frequently Asked Questions
Does this come with an AC adapter?
No — the GG 12 requires a separate 12–18V DC power source. The Proxxon NG 2/S or NG 5/E adapters are fully compatible.
Can I use other bits with the GG 12?
Yes — the GG 12 accepts standard Micromot-compatible bits. Additional diamond, carbide, and HSS bits are available separately.
Is this the same as the 38635 kit?
The No. 38635 Complete Glass Engraving Set includes the GG 12, a transformer, and a full set of bits — ideal if you're starting from scratch.
