Overview
Not a rotary buffer, this DeWalt is listed as a random orbit polisher for car, headlight and windshield glass work. The listing calls it battery powered while also showing two mains voltages.
Random orbit action is gentler on paint than a fixed rotary, and cordless use helps around a car. The listing gives no pad size or battery details, and the mixed voltage figures need checking. Treat the specs as a starting point.
Who it's for
Detailers and car owners who polish paint, lenses and glass at home may use it. Anyone who needs to confirm the power system before buying should ask the seller.
Pros and cons
- Random orbit is gentle on paint
- Cordless operation listed
- Listed for glass and headlights
- Pad size not listed
- Voltage figures conflict
- Battery inclusion not stated
- Weight heavy for a cordless polisher
Performance notes
Random orbit motion stops the pad staying in one spot, so heat and swirl marks build more slowly than with a fixed rotary. Results depend on the pad and compound chosen, since none is listed. Speed is set by the listed rating.
