You can even use them to polish the bottom of your kayak if it’s becoming a little scuffed up. Porter-Cable sanders are among the top names you can find in power tools.

Why You Need a Good Porter Cable Random Orbit Sanders? 

The sanders in this test are all a random orbital sander and have a fitted random orbit pad that measures around five or six inches across. The sanding pads spin and oscillate randomly rather than just in a circular motion. With a random orbital sander, you get less of the swirl marks showing on your workpiece. Also, with a controllable pad speed, you can get the finest finish possible as you move the sander across the grain or body filler.

The sanding tools may offer a slower maximum sanding speed than other sanders, yet they can be more flexible using the hook and loop system to connect the sanding pads onto the base of the sander. We initially questioned whether cordless sanders would be viable for most operations, assuming that their batteries would not give enough charge to complete the task and that the tools would be too cumbersome.

However, we discovered that cordless sanders perform admirably and work several advantages over their corded counterparts. When you need a great finish or need to get rid of sharp plastic edges on something you’ve just cut, then a powerful sander in this range can suit you.

3. PORTER-CABLE Random Orbit Sander with Polishing Pad, 6-Inch  

It’s no surprise that many people, including woodworking professionals and DIY enthusiasts, like Porter-Cable 7346SP because the supplied polishing pad may be used for sanding and polishing.

Because it comes with a polishing pad beside the 6-inch sanding disc, the Porter-Cable 7346SP offers good versatility in that it can be used not just on wood but also on automotive and marine projects. You have variable speed from the start-up at 2,500 to 6,800 orbits per minute from the 4.5-amp motor to get the best finish.

This sander incorporates an adjustable side handle besides the polishing pad for enhanced comfort and control. Unfortunately, the sander lacks any dust control, which can be key factors in using this orbital action sander.

Best Porter Cable Random Orbit Sander Buying Guide 

It’s a good idea to consider your needs before beginning your search for a Porter cable orbital sander. There are various random orbital hand sanders available, and while one sander is suited to one type of work, another may be suited to another. (Read Polishing Concrete Countertops with Orbital Sander)

To pick the best palm sander, ask the following questions:

What do you need the random orbit sander for? If you have a one-time job, a low-powered orbital sander is better suited. A more robust sander, or portable cordless sander, may be required if you have more work. What are the surfaces you’re sanding? If you’re sanding drywall plastered wall, a low-powered sander is maybe enough, but, if sanding a large piece of woodwork or polishing a car, then a more powerful sander is required.

How frequently will you use the sander? Are you planning on doing lots of sanding or using the sander occasionally? Evaluating orbital sander costs and characteristics is important.

RPM vs. OPM sanding pad speed

When comparing random orbit sanders, the speed at which the sanding pad spins is the first consideration.

  • RPM – RPM means the rotations per minute of the random orbit sander.
  • OPM (orbits per minute) are measurements other than RPM. Random orbit sanders are typically measured in OPM, and ones with an RPM rating are hard to compare to those with an OPM rating.

Some orbit sanders can spin on a fixed axis, and you can measure these orbit sanders using the RPM figure.


The motor Amp rating typically determines an orbit sander’s power rating. Most orbital sanders have a motor Amp rating ranging from 2.5 to 3.3 amps or more, although battery-powered variants appear. There are sanders with a more powerful motor, although some sanders with a lower spinning speed (OPM) can be more powerful than sanders with a faster spinning speed.

Dust Collection

When shopping for an orbital sander, the sander’s dust collection should be an important priority. The ability of an orbital sander to collect dust is perhaps the most talked-about function. While most orbital sanders on the market today contain a dust collection unit, not all of them are created equal.

For dust collection, the following are the key features to look for:

  • The size of the dust collection unit varies between sander models.
  • How simple are the dust collection methods to empty?
  • The efficiency of dust collection. Many collect dust in a bag, while some also allow you to connect a hose for total dust removal as you work.


A random orbit sander’s warranty usually spans one and three years. This makes a difference, especially when you look at the size of the sander and how much you will use it.

In addition to the regular warranty, Porter Cable orbital sanders offer a significant warranty and customer support, no matter how you use your sander.
