Best Random Orbital Sander Reviews

The degree of manipulation you are rewarded with a random orbital (RO) sander makes it a great choice for erasing layers of rough material. Each of these RO sanders utilizes circular shapes of sandpaper that merge with the sanding disc via a velcro. Moreover, as the disc spins in an elliptical motion, chances of swirl marks are significantly reduced.

Sanding wooden joints becomes much more efficient as the RO sander is not susceptible to changes in direction of wood grain. Thus performing desirable sanding on a combination of wooden pieces at right angles becomes a piece of cake.

Wondering how does the X-flow dust collector help? It creates an incredibly lethal suction force through 2 small channels. This suction force is because of the narrowness of the X-shaped funnels.

Buyer’s Guide: What to Look for in the Best Random Orbital Sander?

Not all of these RO sanders could be the best random orbital sander for you. Based on your application type, the body size, power rating, base plate size, usability, and overall configuration, would impact the effectiveness of the RO sander.

Here are a few things you must decide between:

1. Power Source

A random orbital sander can either be powered by pneumatic means (compressed air), rechargeable batteries/cordless, or an electric cord. Based on the type of power source, the performance and usability of the sander varies.

  • Pneumatic RO sanders are often used by professionals who do sanding for a living. If you have an air compressor capable of giving an output of 40 CFM or higher then this power source could help you sand huge surfaces in record-breaking durations.
  • Rechargeable Battery/Cordless RO sanders work well if you need to perform sanding in different areas with no power source nearby. The batteries can be changed after a single charge (30 to 50 minutes) has been exhausted. There’s no need for messy cords or extensions.
  • Electric Corded RO sanders are reliable as they offer long usage times. This is because they are powered through a wall socket. If you work in closed spaces or at a specific workstation then corded RO sanders are your best bet.

2. Base Plate/Sander Disc Size

This is a section on the base where the sandpaper is added. Generally, the common disc size for RO sanders is 5-inches and works well for finishing-related projects. However, you can purchase a 6-inch or bigger sized base plate for high-end sanding tasks. For best results, make sure these bigger sized base plates are powered by pneumatic means.

Luckily, you can tweak the sander disc size too. Find an RO sander that lets you attach bigger sander discs for contacting greater amounts of the surface area.

Under 5-inch sanding discs are known to tackle sanding tasks on smaller and more cornered spots. Make sure the process to change the sanding disc is simple and does not take more than a minute to complete.

3. Dust Collection System

You could either choose a quality RO sander that comes with a high-performance dust collection system, or you could opt to wear a mask. Although RO sanders with a dust collection system are generally priced at a few dollars more and are worth it. The system ensures that you can work in a clean environment and you don’t inhale dangerous sharp specks of the material.

When you choose an RO sander with the dust gathering system, make sure the dust storage bag is durable and can expand when filled. You don’t want a poor quality dust bag that tears or even fails to store different kinds of materials due to their varied bulkiness.

4. Orbital Speed

Denoted as OPM, the orbits per minute rating will decide the output your RO sander is capable of. OPM ratings can vary from 4,000 to 15,000. A lower OPM (below 6,500) comes in handy for basic polishing/waxing or sanding soft materials. Whereas a higher OPM (between 6,500 and 10,000) is the perfect rating for finishing applications.

In case you plan to involve yourself in detailed sanding that requires greater amounts of scraping then choose an RO sander with a much higher OPM (between 10,000 and 12,000).

Remember, the best random orbital sander should let you alter between at least 5 to 7 speed settings.

5. Variable Speed Dial

Though the sandpaper grit rating normally defines the quality of sanding performed, an attached variable speed dial offers the operator greater control over the force of sanding. Switching between low and high speeds helps in fine sanding and finishing coarse materials quicker.

You want to study the user convenience offered in case of such dials. The button/switch/knob must be able to be used while sanding. The user shouldn’t have to stop sanding, switch the speed, and then restart.

6. Quality and Reliability

Look for materials in the composition of your RO sander that are durable and sure to sustain rigorous woodworking tasks. Everything from the handle, base plate, motor, hook-and-loop system, and the power source should be constructed with quality materials.

The best random orbital sander would have an extremely tight-fitting grip and absorb 99% of vibrations, all credits to the use of accurate materials.

Also, look for a long-enough warranty. Most RO sanders come with 1 to 2-year warranty options, but for greater sander security you must choose a 3-year warranty.

Frequently Asked Questions (FAQs)

Is an RO sander better than a palm sander?

An RO sander is better than a palm sander when you want to work on larger surface areas. Also, if you are looking at finishing large surfaces that haven’t been painted/treated yet, an RO sander works best. Palm sanders are good for sanding already painted/treated wood.

Can my RO sander act as a piece of polishing equipment?

Yes, an RO sander can be used as a polisher as long as you attach thick felt foam pads. This makes it ready to use on vehicles, walls, and even other equipment.

What does “random” in random orbital sander mean?

The term “random” indicates a randomized motion of the sanding pad. Apart from following an elliptical pattern, the circular pad rotates on the primary axis in a random manner. This is what assures swirl-free and smooth finishes.
