Overview
The Ingersoll 409 is an air-powered die grinder, spinning at up to 27000 RPM in a body that weighs just 1.2 pounds. It runs on shop compressed air rather than a battery or cord, and its speed class suits deburring and detail grinding work.
Ingersoll's pneumatic tools are built around shop air rather than batteries, which keeps the tool body light since there is no motor or cell to carry. At 27000 RPM this sits at the fast end of die grinders, a speed suited to quick material removal on small areas.
- Air powered, not battery or corded
- Up to 27000 RPM top speed
- 1.2 pound body weight
Who it's for
Users with a shop air compressor doing deburring, porting or detail grinding work. It is not an option for anyone without a compressed air source, since it cannot run without one.
Pros and cons

Performance notes
