Best 5 Inch Random Orbital Sander – Guide & Reviews

Sanders are power tools used for smoothing a surface using sandpaper or with any other abrasive material. The random orbital variety employs a mechanism where sanding is done by a round sanding pad that moves in tiny circles and simultaneously vibrating it, for both ultra-smooth sanding and stock removal.

Consumer models are all 5-inch. For every shop and DIYers alike, this item is a must-have, for it gives scratch-free, smooth finishes and is arguably the most versatile and portable electric sander.

Now, professionals who use these tools already know what I am talking about. New or potential users might not have known before, but I believe my brief introduction gave you a slight idea.

Factors To Consider When Purchasing The Best 5 Inch Random Orbital Sander

Before going into the market for a new orbital sander, here are some things to consider because they will be helpful when you acquire the sander for use.

Comfortable Grip

Because it is a hand tool that may be used for long periods of time, I recommend getting one that feels comfortable in your hand. Here, two things come to play; ergonomic design or the material the handle is made of e.g. a soft over mold. The latter also reduces vibration and minimizes fatigue.

When it comes to how a sander will fit and in your hand, different variables should be considered for example one's hand strength and hand size so if possible, while at the retailer's, hold the sander you are considering in your hand and see how it feels.

Dust Collection Feature

Some come equipped with a dust collection feature, where a vacuum sucks the discharged dust through holes in the pad and paper, then feeding it to a bag or canister. Not only does this ensure clean surfaces as you work, but also clean, the dust-free air in your shop hence you do not inhale the dust.

Also, dust may be of harm to the sander itself by clogging parts, rendering it useless. Until you incur those extra costs on the repair. With a dust collection feature, though, machine parts cannot be clogged by the dust, promoting longevity.

Variable Speed

Variable speed on this tool is well worth having, for it gives you control over the tool. An important aspect of a smooth finish is control, and to control you need to be able to choose from different speeds. To smooth a finish, the sander is run at a lower speed.

It is one of the things I would consider, and once you use the best 5 inch random orbital sander with variable speed, you will appreciate this feature.

Motor Power

Different sanders have different motors of different amperage with different RPMs (rotations per minute). Pick an orbital sander with power that fits your needs, be it heavy duty or light work.
