Overview
Compressed air, not a battery or cord, drives the Ingersoll 3101G to a 20,000 RPM free speed.
Running on shop air rather than a battery, this grinder needs a compressor to operate, which suits garage and shop setups more than cordless portability. At about 1.3 pounds it's light enough for one-handed work on deburring or light grinding tasks.
- 20,000 RPM free speed
- Pneumatic, air powered
- About 1.3 pound weight
Who it's for
Shop and garage users who already run a compressed air line will get the most from this grinder's light, fast-spinning design. Without a compressor on hand, it isn't really an option, since there's no cord or battery version.
Pros and cons
- Spins to 20,000 RPM
- Weighs about 1.3 pounds
- Compact footprint for tight spaces
- Requires a compressed air supply, not cordless
- No collet or accessory size listed
Performance notes
The pneumatic motor free-spins to 20,000 RPM, fast enough for removing burrs and light material shaping, though it needs steady air pressure to sustain that speed. Its roughly 1.3 pound weight and compact 9.5 x 6 x 2 inch footprint make it easier to control in tight spaces than a heavier corded grinder.
