Best Corded Polishers in 2020

If you want to keep your car’s exterior looking as perfect as the day you bought it, then you need to be willing to invest in a good polisher. A reliable polisher will give you the ability to buff the exterior of your car without causing damage to the paint job.

Polishers also double as sanders for woodworking applications. Simply detach the polishing pad, attach a sanding pad, and you have a completely different type of tool ready to go.

If you have a car but haven’t invested in a car polisher, then it might be time to considering purchasing one. Below are just some of the benefits you can get from a good polisher.


The traditional method of buffing your car includes using a piece of cloth that you repeatedly rub across the outside panels of your car. This can produce some good, shiny results, but it takes a lot of time and effort to do.


Think back to the times you brought your car to your local auto shop for a waxing. You probably thought that the workers use some sort of magical tool to make your car shine when, in fact, they employ polishers to get the job done. Furthermore, using one is extremely easy and requires no special skills; just a steady hand and patience.

Finding the Right Polisher

A quick search on the Internet will yield thousands of results, making it extremely difficult to choose a good model. Don’t worry. The following segment will inform you of which specs and features should be taken into consideration.

Corded vs. Cordless

The first decision to make is choosing between a corded or cordless polisher. Corded and cordless power tools have their own general set of pros and cons, but when it comes to polishers, we highly recommend getting a corded model. This is because larger motors are needed to reach higher speeds, something that most cordless models don’t feature. You can solve the problem of short power cords with the help of a quality extension cord.

There are two numbers that are used to measure how fast polishers can polish. These are RPM and OPM. How fast the buffer spins depends on the motor installed in the unit. The best models should reach a maximum RPM of up to 600 and OPM of around 6,000. Of course, higher speeds translate into a greater loss of control, so it would be great to have some way to control how quickly the unit buffs.

Variable Speed

This is the system that can help you gain control when using a polisher is a variable speed dial, switch, or knob. The best models should allow you to control how quickly the attachment moves, especially since different surfaces require different speeds to prevent damage.


Obviously, a high-spinning tool like a polisher will produce tremors up your arm, potentially causing fatigue and pain. Look for a model with a comfortable, rubber handle; is large but a manageable size; and doesn’t vibrate too wildly when running at its highest speed setting.

Like any handheld power tool, the weight of the unit plays a role in determining how easy it is to maneuver. Corded buffers come in all shapes, sizes, and weights. They commonly weight between 5 and 15 pounds. We recommend purchasing a model that’s easy to lift. Maybe a little weight isn’t a bad thing if it helps balance the unit when using it.

When looking for a polisher, there are several aspects to consider. The first thing to consider is the speed. Looking at the unit’s motor could give you an indication of how quickly the unit spins and orbits, meaning that you’ll spend less work on sanding and polishing applications.
