Best Orbital Sander For Ultra-Smooth Surfaces

Best Orbital Sander For Ultra-Smooth Surfaces

If you are fond of DIY projects around your home, an orbital sander is one of the handy tools you can buy. Accordingly, an orbital sander effectively smoothens surfaces such as wood and plastered surfaces within your home. Ideally, a random orbital sander will help you achieve extra-smooth surfaces with minimal swirl patterns.

Therefore, we have compiled a comprehensive buying guide for the best orbital sander. Nonetheless, before we get to the reviews, let's first understand the basic concept of an orbital sander.

What is an Orbital Sander?

An orbital sander is a hand-held tool that is used for sanding. This power tool applies the random-orbit action for sanding a surface for a final finer finish. Depending on the sanding task at hand, you can find different sizes and models of orbital sanders.

After smoothening, an orbital sander leaves swirl marks on the surface. With a random orbital sander, you can expect finer and cleaner finishes with a reduced likelihood of swirl finishes. Having identified the application of a sander, let's review the best five products in this category along with their pros and cons.

Factors to Consider Before Buying the Best Orbital Sander

1. Sanding Pad Speed – RPM vs. OPM

The first thing to check in any random orbit sander is the sanding speed. Specifically, the smoothening pad is the one that spins, and different manufacturers use different speeds units. On the one hand, the sanding pad speed can be measured in terms of RPMs, representing the number of revolutions a pad makes in a minute. However, RPM speed measurement can be misleading because a smoothening pad oscillates and spins randomly rather than on a fixed axis.

On the other hand, OPM represents the number of orbits a pad makes per minute. Fundamentally, the use of OPM is ideal because it measures speed more accurately. Therefore, OPM speed measurement is ideal for sanders that spin randomly and operate on variable speed rather than on a fixed axis. However, fixed orbital sanders are suited by the RPM measurement due to their fixed speeds.

During purchase, it isn't easy to compare the measurements of RPM and OPM between random orbit sanders. Nevertheless, the speed should also be judged based on the power of the individual best random orbital sander. Additionally, the indicated speeds are measured when a sander is rotating freely rather than while in use. Therefore, you should expect the speed to reduce due to friction upon contact with a surface.

2. Power

An orbit sander comes with a motor AMP power rating. Most speed motor AMP power ratings range between 2.5 and 3.3 AMP to indicate the power capacity of a hand sander. In most cases, the power of a random orbit sander is usually measured against its variable speed. However, you may have an orbit sander with lower OPM rates but is more powerful than another spinning faster.

Subsequently, a powerful motor means that the sanding speed of a tool will not be reduced much due to surface friction. Therefore, a sander with a strong motor is guaranteed to run more efficiently at stable speeds, making sanding sessions easier with better outcomes.

Besides the power of a motor, you should consider the power source while looking for the best orbital sander. The two options under source are corded and wireless sanders. A corded random orbital sander works by being plugged into a power source, while a cordless sander uses voltage from a rechargeable battery. The latter sander option offers the advantage of portability but has limited run time.

For adequate powering, you can opt for one of the brands on our list and avoid a less powerful brand like Porter cable. Porter-Cable sanders may feature less power and fixed speeds.

3. Dust Collection

Another important feature that most sander users look out for is the dirt collection capability of random orbital sanders. Dust gathering closely follows the sanding performance. Orbital sanders available in the market today are built with a dust collection kit but with a wide range of dirt gathering capabilities. Some of the critical factors to consider for dust-gathering include:

  • Size of dust collector.
  • Ease of emptying and removing the dust collection system or dust bag.
  • Dirt collection effectiveness. The best random orbital sanders should filter the smallest dust particles of up to 1.5-micron diameter.

Regarding how dirt collection happens, a random orbit sander is built with a feature that sucks sawdust into a canister or bag that requires occasional emptying. Other high-end orbit sanders are equipped with an attachment to a shop vac. Even with an enhanced dirt-gathering system, you should ensure you wear protective eye protection and a mask to avoid injuring your respiratory system and eyes while smoothening.

Overall, the best random orbital sander should have an in-built sawdust collector. The best random orbital sander should also allow extensive smoothening without the disruptions of a filled sawdust bag.

4. Disc Size

The sander tool requires the attachment of a disc with a smoothening pad. Traditional orbit sanders are built for a square disc, while random orbital sanders are built for circular discs. Many common random sanders have a 5-inch to 6-inch sander disc diameter, with heavy-duty sanders having a diameter of 8 inches. However, you cannot swap the disc sizes, such as fitting a 6-inch disc onto a 5-inch random orbital sander.

5. Ergonomic Design

Considering that smoothening requires physical effort and takes time, you need to consider purchasing a tool with sander features that suit your comfort. Essentially, the handle placement of a sander determines the ergonomic design with either handle placement on the side or front. In addition, the placement of a sander handle ensures that you can work on large surfaces with less fatigue.

Also, ergonomic considerations for tight spaces should feature easy-to-remove handles to provide convenience whenever you encounter obstructions. Additionally, versatile handle adjustments work to ensure that you work on any angle with less hassle. Considerably, if a tool's handle is prone to more vibration, it might be strenuous while smoothening.
