The DWP849 is DEWALT's corded 7-in./9-in. variable speed rotary polisher with a 12-amp motor producing up to 3,500 RPM. Soft start technology prevents initial pad spin-up slinging compound, and an electronic speed control dial maintains consistent speed under load. Ball-bearing construction provides durability for professional detailing and paint correction work.
What is the soft start feature on the DWP849?
Soft start gradually ramps the pad speed up from zero when the trigger is pressed rather than jumping immediately to the set speed. This prevents compound and polish from being slung off the pad at startup, keeping the work surface and surroundings clean.
What pad sizes does the DWP849 support?
The DWP849 supports both 7-in. and 9-in. backing pads via the standard 5/8"-11 spindle thread. Using a 9-in. pad increases coverage area for faster polishing on large flat panels such as hoods and roofs.
How does the DWP849 maintain speed under load?
An electronic speed control circuit monitors motor load and adjusts power delivery to maintain the dial-set speed even when pressure is applied to the pad. This helps deliver consistent results when working through polishing compounds.
Is the DWP849 suitable for professional detailing?
Yes. The 12-amp motor, variable speed range, soft start, and ball-bearing construction make the DWP849 a professional-grade corded polisher. It is widely used by detailing shops and body shops for paint correction and finishing work.
Does the DWP849 require a battery?
No. The DWP849 is a corded electric polisher that plugs directly into a standard 120V outlet. No battery or charger is needed, and the full 12-amp power is always available regardless of battery state of charge.
