We will be comparing the Porter Cable 7424xp vs 7346sp. These two sanders need a detailed review to choose the one that meets your requirements. Porter Cable is a leading brand with high-quality and professional-grade orbital polishers. This article follows a thorough review of both products, explaining the pros and cons so you can choose the one that works for you.
Overview of the Porter cable 7424xp
The Porter Cable 7424xp is a random-orbit machine powered by 4.5Amp. The speed varies from 2,500 to 6,800 OMP. It accommodates 5/16-24 spindle thread accessories. It comes with two removable handles that make handling the tool easy. The roller bearing construction makes the machine durable. The size and weight are perfect for the position you will be working on. You can use both hands but with ease.
If you do not use the screw on the handle, it will not compromise your production. The sander is comfortable to use and reaches small corners in a car. These include under the mirror, and it remains effective. The sander does not require a lot of maintenance. You do not have to lubricate it since it is lubricated by high-quality lube that lasts for life. However, it would help if you remembered that it is also an industrial tool that occasionally needs cleaning and checking parts. That is for safety and performance.
There are a few drawbacks when it comes to the tool. When you are operating at low speeds, it becomes difficult to control the tool. It tends to slow down a bit. The pad comes with cheap foam that does not last long. However, polishing pads are easy to buy at an affordable price. You may even get them with some accessories.
- Speed variance
- Compact size
- Zero maintenance
- It is tricky to control at low speeds
- Cheap foam pad
Key Features of the Porter cable 7424xp
The 4.5Amp motor is powerful in the way it enhances speed. The Dual Action polisher has a better switch design that makes it durable. The Porter Cable motor does not give a biased performance when using the other option. The speed and quality performance remain the same during sanding and polishing. A faster removal rate is what comes with the machine.
The machine comes with two removable handles. They have an ergonomic design that makes them comfortable to handle. The handles allow you to move the sander with ease on tricky corners.
The polishing pad works on surfaces with scratches or unwanted paint. It gives you a beautiful excellent gloss finish. Unlike the SP series with a sanding disc, the XP model only has a polishing pad. However, you can still get a sanding disc that comes with an extra cost.
Rotations per minute
The Dual action process produces a small amount of heat you might withstand. It has a speed variance of 2,500 to 6,800 OMP. That is faster than what the 7424 gives. The aggressiveness that comes with the sander makes it efficient, effective and reliable. That makes it ideal for tough surfaces.

It comes with a 6-inch proprietary counterbalance that you use with the 6-inch sanding pad. It is compatible with 5/16-24 spindle thread accessories. It works in two positions as it comes with two removable side handles.

Key features of the Porter cable 7346sp
A sander is a machine that has a speed variance. It varies from 2,500 to 6,800 opm, which is the ideal speed range for tough surfaces. It easily maneuvers in tricky corners at a higher speed. More speed does not mean you will not experience heating, but it is minimal.
The tool has two side handles that help you carry the machine around. There are tricky areas where you need control from both hands. The ergonomic design gives you a good grip. You can hardly handle the sander with uneasiness.
A fast removal rate and a smooth polish on swirls, spots and scratches require safety features to avoid injuries. The power that results in that has to be protected from hurting the user; hence the orbital motion does not burn the user.
The switch design that comes with the SP model I clearly defined. It deactivates the motor as soon as you press the button. You will not have a running machine without activating the On button. That keeps you safe from the aggressive tool.
The SP has a feature that makes the polishing process exceptional. It comes with both the polishing pad and the sanding disc. The fast speed that comes with the 4.5 amp motor makes the tool efficient. The saw is tailor-made for high overload protection. It makes the sander ideal for polishing and sanding automotive and marine projects.
- Both products have an electronic variable-speed dial of 2,500 to 6,800 OPM.
- A 4.5 amp motor powers them.
- They have a wheel diameter of 6 inches.
- The SP series is ideal for more serious polishing than the XP model.
- Both products are for sanding and polishing.
Differences between Porter Cable 7424xp and Porter Cable 7346sp
- The Porter Cable 7424xp has a polishing pad, whereas the 7346sp comes with a sanding disc and a polishing pad.
- The XP version is more affordable than the SP.
- The SP series works as a sanding tool; hence it is named sanding pad since it comes with a sanding pad and a polishing pad.
- The SP series is ideal for more serious polishing than the XP model.
They are in the same price range. That is due to more similarities that come with both polishers. However, the XP model helps you save a few bucks.
If you are looking for a model with a polishing pad only, you can go for the Porter Cable 7424xp model. Although both products fall under the same price range, the Porter Cable 7424xp model will help you save some cash due to the sanding disc that it does not include inside the package. I recommend the same model if you want to save extra money.
However, if you need both the sanding and polishing pad in one tool, I advise you to go for the SP model. You can still use the XP model with an additional polishing pad. It is a 2-in-1 model that comes at an extra cost.
