PORTER-CABLE 7424XP Polisher Review

Porter-Cable-7424XP Variable-speed Polisher

The Porter-Cable 7424XP 6-Inch Variable-Speed Polisher is latest version of the excellent Porter-Cable 7424 random orbital polisher that was introduced ten years ago. It has been very popular ever since. The main reason for its popularity is that it offers very good value for the money. Additionally, the Porter-Cable 7424XP is easy to use and thanks to the random orbital motion it can be used also by beginners without causing any damage.

The Porter-Cable 7424XP makes it easy to remove swirls, polish paint and apply wax. It saves a lot of time and is reasonable lightweight to make it possible to use the polisher for longer periods of time. The new 4.5 Amp motor is powerful, which makes it possible to finish the job quickly.

The Porter-Cable 7424XP features variable speed (2,500-6,800 OPM) and random orbit, swirl-free polishing action. It includes a 5″ proprietary counter balance and accepts 5/16 – 24 spindle thread accessories. The 7424XP has a two-position (left or right) removable side handle for greater comfort and control. The compact and lightweight (5.5 pounds) design makes it easy to operate. It is also relatively quiet.

A dual-action polisher, such as the Porter-Cable 7424XP, is characterized by the motion of the head. It spins on a central spindle, and this spindle rotates around an eccentric offset. This is why they are also called random orbital polishers. Thanks to the dual action, the risk of burning the paint is minimized.

The Porter-Cable 7424XP polisher comes with a one year warranty. Note that while the 7424XP comes with a 5″ counter weight, no backing plate is included. If you want to use hook and loop pads, you need to buy a hook and loop backing plate. Only one small polishing pad is included with 7424XP. Also note that this is a dual-action polisher, not a circular polisher.

“Use this buffer on three of my vehicles,held up great,worked great. Went to chemical guys on line to see which speed for which wax and sealers to set speed for buffer. Very happy with results.”

“I’ve always been a “by hand’ purist but after reading all the positive reviews, I decided to try this thing out. I must say that I am totally impressed. It makes the entire job so much easier and the product goes on so much more evenly. The machine is maneuverable enough to get to almost any area of the car and controllable enough to do exactly what you want. The results are impressive due to the evenness of the application.”

“I have been using the porter cable for a couple of years and I have to say that I love it. I would never go back to hand polishing again. I love the fact that this machine makes it 10 times faster when making corrections and it kinda makes it hard for you to dig too deep into the paint. I would recommend this to any newbies like myself that just want to do some polishing”
