Rated 4.7 out of 5 by 23 reviewers.
Rated 5.0 out of 5.0 by High Quality, Tough Construction I purchased this Dewalt DWP849X Variable Speed Polisher with Soft Start last month for two jobs. First, I needed a 7 in, grinder to remove excess concrete on our patio slab for proper drainage. Standard grinders don't have soft start or variable speed which I needed for greater control of the $100 diamond grinding wheel. The DWP849X soft start, variable RPM, power and internal electronics to HOLD that RPM under load were invaluable and impressive. The unit sustained several days of grinding and sanding with the vibrations, dust, and heat generated from the heavy work loads. I covered the lint screen air intakes with a cotton cloth to filter some of the dust that wasn't blown away by my fans. It was the perfect grinder for the job. Afterwards, I cleaned the unit with compressed air, and she looks, starts, stops, and operates like new. Very tight and rugged unit. The primary purpose for the unit will be to clean, polish and buff our 26 gel-coat boat. I have no doubts that it will handle that duty with ease. The rubber head cover is a big plus and the large rounded head handle makes all the difference in control and user comfort. A great buy!! February 11, 2015
Rated 5.0 out of 5.0 by Dewalt buffer delivers productivity The Dewalt buffer certainly held up to its description. Meeting all expectations and completion the job with no issues made my week. The Dewalt buffer was used for 3 days straight and preformed well during every hour of operation. April 8, 2014
Rated 5.0 out of 5.0 by great product Polisher is much quieter than what I expected from the other reviews. Great trigger, everything works as expected. I believe this product will last a long time seems to be built well July 21, 2015
Rated 5.0 out of 5.0 by GREAT PIECE OF EQUIPMENT It does have a bit of a jump in RPM when you first start working with it. But in no time I was more than used to it and enjoyed working with several types of polishes and compounds. Great range of RPM's. All the power you'll ever need. March 25, 2015
Rated 5.0 out of 5.0 by converted it to a wet grinder This grinder is awesome, you can run it hard for hours and it never even get hot. Makitas version of this ismt rated for quite as many amps and just cant take the heat.. I let the smoke out of one right before i bought the dewalt. The cord is two feet longer than makitas and a heavier gauge right where it goes into the handle the sleeve is thicker and doesnt delaminate quite like the makita did and i like the filters on the vents that kept all the material out of the motor. I would definately buy it again given the choice between this and any other grinder November 14, 2014
Rated 4.0 out of 5.0 by If pnematic isn't an option; this is it. It's a little bulky. It is built to last though, and the variable speed is torquey compared to running air. The pad is small and stiff, but that's replaceable. Don't try to use the extremely cheap wool cover's on it, for compounding it will burn right through the edges after a minute of use. April 16, 2013
Rated 4.0 out of 5.0 by Good purchase The polisher Works great, it has a sottstart feature, and also it can keep a constant speed without load or under load... Sincé it has a hook & loop pad, It's kind of difficult to center the buffing pad... You'll see that the polisher kind of jumps when polishing at moderate speeds and higher.... September 23, 2014
Rated 3.0 out of 5.0 by Dewalt DWP849X is poorly advertised and is an incomplete tool as sold. This product is stated as a 7 in. and 9 in. polisher, but does not have any 9 in. pad. Dewalt does not offer a hook and loop polishing bonnet to go with the 7 1/2" hook and loop pad provided. I bought your bonnets, and that required me to buy an additional 7 1/2" rubber pad (dw4990). Your bonnet do not work with the hook and loop pad provided. If I want to use a 9" bonnet, I will have to purchase more accessories. The only hook and loop bonnet that might work is provided by Makita. April 29, 2014
