Best Pneumatic Random Orbital Sander Buyer’s Guide

Although we have various sanders to choose from, many woodworkers still struggle to identify the best product to use for their projects. The sanders have similar features that may make someone believe that any tool can do the job. They also perform similar functions, and if one is not keen, they may overlook specific attributes that would give better results.

Beginners usually find it hard to choose a tool because they may not fully understand what to look out for as they shop. We also have some professionals that may conflict between two sanders, wondering which one to use for different heavy-duty projects.

This section will give more insight into the reasons for having the product in your workstation, considerations to make before selecting one, and some of the frequently asked questions by users.

Reasons for Buying the Best Pneumatic Random Orbital Sander

• Compact and lightweight design. The orbital sander is easy to move around with and does not tire you even during extended work sessions. Its compact design also makes it safe and easy to operate, thus suitable for beginners and pros.
• Dust collection bag. Since it is impossible to use a sander without thinking of dust collection, a random orbital device helps you forget about the mess as it collects dust. Your only concern is to empty the bag once you notice it is overflowing.
• Comfortable handle. The machine provides a firm grip to give you control and comfort. You can work as long as you want because the handle also perfectly fits your palm to prevent strains.
• Durable aluminum body. You can use the tool for a long duration as it has a sturdy body that keeps it in good shape. Its composite cover also enhances its longevity and makes it a valuable tool for longer.
• Speed adjustment lever. The device provides the user with the option of adjusting and customizing the speed level to provide versatility. You can use it on different projects regardless of the required speed because the tool matches up.
• Maintenance. You can easily maintain the tool by keeping it in a dry station away from water or moisture elements. The sander has a compact design that prevents dust and particles from damaging the motor; thus, it stays in good shape without incurring costs.

Factors to Consider When Purchasing the Best Pneumatic Random Orbital Sander

• Dust collection

During sanding, you may kick up a lot of sawdust, making you prefer a sander with a built-in dust collector. This feature collects dust and allows you to work in a clean environment. You will need to empty the dust section periodically to avoid the dust spilling over.

• Disc size

The product uses round sandpaper discs available in various sizes to accommodate lightweight or heavy-duty applications. It is difficult to swap discs because the sanders can only fit one disc type. Therefore, if you need to work with a large disc, please ensure you acquire a suitable sander.

• Power source

Some sanding machines require an electrical source, while others work with a rechargeable battery. Therefore, you need to identify your sanding requirements to get the most suitable device.

For example, if you are working with a corded unit, you need an extension cord to engage in outdoor sanding projects.

A cordless orbital charger is more suited for exterior applications, but you should charge the battery before you begin as it will help the device perform for a longer time non-stop.

• Application

You need to assess your project needs before committing your money because the reason for purchasing a sander will always dictate what you need.

For example, if you are engaging in commercial and heavy-duty sanding and finishing products, you have to get a tool that has a great capacity and powerful performance.

On the other hand, light household sanding projects require a simple, lightweight sander for excellent results.

• Budget

The machine’s prices vary depending on its nature and additional features. Therefore, once you determine your job needs, you will know how much money you should be willing to spend.

Some devices are more expensive than others because they have added accessories. Thus, if you have more to spend, you can consider such and maximize the opportunity.

• Speed Adjustment

Since various projects require different sanding speeds, you need to constantly check if you need a tool that allows you to customize its speed.

If the project does not need speed adjustments, a standard sander will do a great job. However, if you are working on a commercial project that requires a specific finish, please get a speed adjustable tool.

• Powerful motor

The unit uses a motor, which significantly determines the power and performance it delivers. A powerful engine is an ideal pick to avoid the tool breaking down because of pressure.

You can also consider whether the motor has a lot of noise and what kind of vibrations it gives. This aspect determines if you can comfortably use the tool for long as a loud noise and high vibrations wear you out quickly.

• Pad size

You need to get a pad size that best suits your application. Generally, heavy-duty applications will require a larger pad size for a better performance level. A larger pad size clears up a large surface area quickly.

On the other hand, if you are sanding a wood deck or a smaller sanding project, an average pad size is good enough.

Frequently Asked Questions

• What disc size should I use?

The choice of a disc size relies on the project’s nature because if you are working on a heavy-duty task, you will need a vast disc.

• Is there a difference between a random orbital sander and a traditional orbital sander?

A random orbital sander features a circular sanding pad, runs in an elliptical manner, and can make significant wood and metal changes for more refined finishes.

On the other hand, a traditional sander’s pad is a square and only runs in an orbital way.

• What are the significant features that distinguish random orbital sanders?

You will find electric-powered sanders that require an electric power source, while others are pneumatic powered. We also have corded and cordless orbital sanders that you can choose from depending on whether you are working outdoors or indoors.

A dust collection bag is another feature that distinguishes these products. Some products do not have a dust collector, while others feature a dust collection unit to collect dust as you work.

• Is there a recommended pad when using the sander?

The pad type and size usually depend on the material you are sanding. For example, a large and rough project will demand a coarse pad. On the other hand, for final, smooth finishes, you need a fine-grained sanding pad.

Working Tips

• You should always wear eye protection when engaging in grinding and sanding applications. You can also consider getting a dust mask or respirator to protect your entire face from dust and other particles. This practice will help you avoid breathing problems and lung damage.
• When working on small objects, ensure you hold the device with one hand and the working surface with the other. You can also get a clamp to help stabilize the material for more safety and control.
