PORTER-CABLE 7424XP Variable-Speed Polisher Review

Best-selling Polisher/Buffer

The Porter Cable 7424XP is one of the most popular polishers. But do you really get good value for your money? The short answer is yes!

Without slightest doubt, the Porter Cable 7424XP is a very good polisher. It is easy to use and thanks to the dual action, the risk of swirl marks or burning the paint is minimized. At 5.5 pounds, the Porter Cable 7424XP polisher is lightweight, making it easy to use also for longer periods of time. It does not vibrate much and it is relatively quiet.

The Porter-Cable 7424XP has a number of useful features. For example, variable speed, 2,500-6,800 OPM, with 12 different speed settings. Additionally, it includes a 5 inch proprietary counter balance and has a two-position (left or right) removable side handle for greater comfort and control. Thanks to the 4.5 Amp motor, getting rid of light swirl marks or scratches is quick and easy. But for heavier tasks, you may prefer a more powerful polisher.

The 7424XP comes with a 5 inch counter weight but no backing plate. If you want to use hook and loop pads, you need to buy a hook and loop backing plate.

The Porter-Cable 7424XP polisher is backed by a one year warranty.

Dual action means that the head spins on a central spindle, and this spindle rotates around an eccentric offset. This is why it is also called a random orbital polisher. As mentioned, the advantage of the dual action is that risk of swirl marks or burning the paint is minimized.


  • Safe and easy to use, also for beginners
  • Compact and lightweight design
  • Excellent value for the money


  • Not powerful enough for heavier tasks

This buffer using the Astro 4606 6-Inch PU Velcro Backing Pad and Hex-Logic Buffing Pad Kit becomes a complete package for maintaining your vehicle. This buffer will run at low rpm as an orbital buffer spreading the wax smoothly and evenly over the paint, then increase the rpm to medium or high and it becomes a high speed polisher.”

“This machine is the real deal! It is durable and very easy to use, and best of all it really does wonders on your vehicles paint. The 12 speed settings (1-6 at 1/2 increments) make this polisher so dynamic and great for any project. With the right product & pad combination, almost any paint defect can be removed. I highly recommend the PC7424xp to anyone who is looking for a high quality dual-action polisher.”

“I use this polisher on my car and couldn’t be happier. It’s nice to know I won’t burn the finish due to my inexperience. The results are amazing. I’ve had this for a few years now and it still runs like new.”
