Also, the build quality is exceptional. People love how durable it is, and porter stands behind there product offering a full one year warranty with a limited three year one. This means if any issues come about you shouldn’t have any problem getting them resolved. Some people have had issues with the bearings going bad in newer models.

Now we will look at the Porter Cable7424XP. It is similar to the porter cable 7346SP. The motor is of the same high quality, and it comes with the same warranty plan. The motor still runs off 120 volts and at a variable speed of 2500-6800 OPM.

It even comes with similar things out of the box such as the wrench, handles, and polishing pad. However, one thing it does not come with is a sanding pad. This means if you want to sand you will have to buy a sanding pad separately.

Like the 7346SP the 7424XP can take any pads and accessories that have a 5/16 – 24 spindle thread meaning that getting other pads isn’t an issue, but it is annoying that you can’t sand right out of the box.

This model is also easy to use and balanced well, especially when using the two position handle attachment. The size of this unit is very similar. It is lighter at 5.75 pounds, but it is longer measuring 14”x6.5”x6”. This extra length has made it harder for some people to stick it in there bag and take it on the go.

This still is a good variable speed orbital sander though. The pads still work just as well an is swirl free. The build quality is also just as good. Many users are happy with how long this model has lasted for them.

It is a workhorse and can do any sanding or polishing you need. The fact that you can use it without the handle attachment is helpful and cuts down some of the size and weight. If you like switching hands for different angles, then you probably won’t want to use the handle.

Also, the speed controls being a wheel makes it very easy to choose the speeds you want. This is handy because you don’t have to guess what rate you have it set too.

Which Should You Get?


Choosing between the two can be hard because they are so similar, but the porter cable 7424XP is the better option for most people.

The fact that it is lighter means that it is easier to control and also easier to take with you. On top of this, it is the more durable option. While the 7346SP is a good sander, it usually doesn’t last as long as the 7424XP. When buying a tool you want one that is top quality and can be a workhorse for you. The 7424XP is just that.

Also, when it comes to speed controls, the 7424XP is more comfortable to set.

Lastly, you are probably going to want to buy new pads anyways, so the fact that the 7424XP doesn’t come with a dedicated sander pad isn’t that big of a deal. The pads out of the box are cheap, and while they can work to get the best results and no swirls or marks left behind, you will want to get some better pads.

However, they will both do the same job, so you can choose the 7346SP because cuttingly it cost less and comes with a sanding pad.

Uses for Orbital Sander

After comparing the sanders though you should probably have a rough idea of the uses for one. Well, you can do all kinds of things with an orbital sander, and sanding is only one of those things.

They are suitable for sanding wood to get a smooth finish before staining or removing the old stain, but you can also use them on other surfaces besides timber. You can use them to sand down paint on your car for example if you want to repaint it or you can even smooth down other metal.

Outside of sanding you can also polish things with an orbital sander. The rapid circular motion with the right pad can brighten up metal services or even painted ones. With an orbital sander, you can get a bright shiny finish fast on things.
