Categories : tools
SKU : WOR-TOO-063
The DEWALT DWP849X 7-Inch/9-Inch Variable-Speed Polisher is made for serious detailing work—from removing oxidation and swirl marks to applying polish and wax. Its 12-amp motor spins 7- and 9-inch pads up to 3,500 RPM, while a variable speed dial and trigger let you dial in the exact aggressiveness for each step.
If the pad isn't spinning or stops under pressure, first check that the backing pad is tight on the spindle. Use the spindle lock to secure it while tightening. Also make sure you're not pressing too hard—this polisher is designed to work with light-to-moderate contact. If the pad slips, reseat it and verify the backing plate is rated for the pad size you're using. Always start with the variable speed dial low and increase gradually to avoid stalling.
Whether you're a professional detailer or a weekend enthusiast, the DWP849X gives you a smooth, controllable finish on paint, gel coat, and metal.

Start with low speed (800–1,200 RPM) for applying polish or wax, then increase for compounding or cutting. The variable dial lets you set a top speed, and the trigger allows momentary control.
Always use a backing pad that matches the size of your disc. Never force the pad against a curved surface at an extreme angle. Make sure the wool pad is properly installed and not worn.
The replaceable wool ingestion shield stops fibers from being pulled into the motor housing. Check it periodically and replace it if it becomes threadbare to keep airflow strong and protect the armature.
Excessive pressure can stall the motor. Ease up on the pad and use a lower speed setting. Also make sure the backing pad is tightly secured.
Use the spindle lock to hold the spindle still, then rotate the backing pad counterclockwise to remove.
It accepts 7-inch and 9-inch backing pads, and the included pads are compatible with either size depending on the attachment.
Yes, it's ideal for paint correction, polishing, and waxing with wool or foam pads.
Yes, with appropriate sanding backing pads, it can be used for dry sanding.












Great polisher. Smooth.
I used this to polish my car. The variable speed is really helpful. It's a bit heavy but manageable.
I've been detailing cars for 25 years and this is one of the best polishers I've used. The soft start prevents sling, and the 0-3500 rpm range gives me total control. I can do a full correction in half the time. The build quality is solid. Definitely worth the money.
This thing rips. Made my boat look brand new. No swirls left.
Works well. A little loud.
I bought this for my son and he loves it. He does car detailing on the side. The case is nice and it feels sturdy. I'm told it's the best on the market. Happy with the purchase.
It's a good polisher but I expected more power at lower speeds. The handle gets hot after long use. Still got the job done.
I'm a beginner and this was easy to handle. The variable speed let me start slow and build confidence. My paint looks better than the dealer's. Very happy.
No nonsense tool. Does exactly what it should.
This replaced my old polisher that finally died. The difference is night and day. It's quieter, smoother, and I can actually feel the variable speed making a difference. I've already used it on three cars. Highly recommend.
Good tool. I wish the cord were longer.
Used it on my Jeep and it did amazing. The soft start is a game changer. No more compound splatter. Definitely a keeper.
