Despite its power, the 7424XP Polisher also offers high precision, thanks to its variable-speed motor. At the base of the unit, there is a dial control, making it easy to place the speed wherever you want it. The variable speed ranges from 2,500 to 6,800 orbits per minute (opm). This wide range gives you precise control for a delicate finish.

Easy to Use

All the while, the 7424XP Polisher is easy to use. The speed control dial means that you can easily and comfortably adjust the speed to the job. Beyond that, the publisher also includes a two-position removable side handle, making it comfortable for both right handed or left handed users alike.

You can also use this polisher with a variety of pads and accessories. The 7424XP Polisher except 5/16 to 24 spindle thread accessories, making it versatile too.

Porter-Cable has been producing durable tools for decades, and the 7424XP Polisher is no exception. This polisher is designed with a full ball and roller bearing construction. This ensures that the tool can withstand heavy-duty or industrial-weight loads.


Potentially the only drawback with this model is the vibration. Under a higher speed, the tool vibrates so much that the front cover can actually fall off. This makes a tool kind of inconvenient when used at higher powers.

Issues with vibrations can also make the tool more difficult to use. Especially if you want to use this polisher for long periods of time, expect your hand to get tired after a while from all of the vibrations.

What is the warranty like on the 7424XP Polisher?

The tool is backed with a 3-year limited warranty. This includes any defects due to faulty materials or workmanship by the manufacturer. On top of that, it also comes with a 90-day money-back guarantee and a 1-year free service contract. Under this contract, Porter-Cable will repair the tool and replace worn parts for free.

Is this tool good for beginners?

Yes, the 7424XP Polisher is good for beginners, but it is also a tool that will last you as you get more experienced with polishing and sanding.

Can I use this tool as a sander?

Yes. You can change the backing head and include a sandpaper disc.

With that being said, you might not want to sand with the same tool you polish your car. You run the risk of getting sawdust and other particles of grit on your polisher. When this happens, you can accidentally rub it into the car surface, scratching the paint in the process. For this reason, it may be best to use this tool strictly for polishing purposes.

If you are on the lookout for a sander, Porter-Cable actually sells a sander/polisher version of this tool under model number 7346SP.

What the Users Say

We wanted to compare our findings with that of others. Almost all users were excited with the power and usability that came with the 7424XP Polisher. Still, there were a few negative comments, mainly regarding the vibration and pads sent with the polisher.


As for the benefits of this tool, many users were happy to admit that they were amateurs and had never used a polisher before. Yet, they found this tool incredibly helpful and easy to use. Several people noted that it was a game changer for those who had been polishing their cars by hand.

The durability of the 7424XP Polisher was noted too. Out of the box, most reviewers said that the tool felt like it would last a long time. These expectations were matched by people coming back 3 or so years after the initial purchase to say that their polisher still works just as good as it did when they first bought it.


As for the drawbacks, several people noted that the tool vibrated pretty heavily. Our own model vibrated a lot. So, we completely agree with this drawback. If you intend to use the tool for a long amount of time, expect to have to use a little bit of muscle.

Users were also generally displeased with the sponges and pads that came with the model. Most recommended buying separate pads or sponges because the ones included are simply cheap garbage. Though we wouldn’t say that they are garbage, you certainly won’t be upset getting separate sponges.

Although the 7424XP Polisher is technically suitable for professional use, we recommend it being used for beginners and amateurs. The power matched with the precision and easy-to-use features make it a no-brainer and game changer for those who have never used a polisher before. You just might want to prepare for the vibration and buy separate sponges.
