Overview
Running on shop air rather than a battery, Gunpla's AT-010K reaches 58000 RPM while weighing just 150 grams for one-handed detail work.
Pneumatic die grinders can spin far faster than electric ones because their speed is not limited by battery voltage or motor torque curves, and 58000 RPM sits well above what a cordless grinder can reach. At 150 grams, this reads as a small pencil-style unit meant for fine detail rather than heavy grinding.

Who it's for
Fits hobbyists and technicians doing detail grinding, deburring, or polishing on small parts, provided they already have a shop air compressor. Not useful without a compressed air line, since it has no battery or cord option.
Pros and cons
