Overview
The Chicago CP860 is an air powered grinder that runs at 24,000 RPM with a 400 watt motor. It weighs 1.26 pounds and measures 5.75 by 2 by 4 inches, listed under Tools and Grinders.
The combination of high spindle speed and a compact, sub-1.5-pound body points to a die grinder built for detail work rather than heavy stock removal. It runs on compressed air rather than a plug or battery, so it needs a compressor to operate, and the listing does not detail hose fittings or air consumption.

Who it's for
Buyers who already have a shop compressor and need a light, high speed grinder for deburring, polishing or detail work in tight spaces fit this listing. Anyone without a compressor, or who wants a corded or battery-powered grinder, should look at other options.
Pros and cons
- High 24,000 RPM spindle speed
- Compact and light at 1.26 pounds
- Small 5.75 inch body fits tight spaces
- Requires a separate air compressor
- Hose fitting and air consumption not published
Performance notes
24,000 RPM is a high spindle speed suited to fast work on small bits, deburring and polishing rather than heavy material removal. The 1.26 pound weight and compact 5.75 inch body support extended one-handed use in tight spots, though actual output depends on the connected compressor supplying enough air pressure and volume for the tool.
