Best Cordless Polishers

If you’ve put a lot of time and money into your car, then you won’t want it getting damaged – even if it’s just small scratches and dents.

This is why polishers exist, because they help to smooth out the imperfections, returning your vehicle to its normal appearance.

Best Cordless Polishers

However, polishers aren’t the most versatile of tools, which is why cordless polishes were invented.

But what do they do? And what are the best ones available to buy on the market?

Well, we’ve got the answers for you! In the guide below, you’ll find out all about cordless polishers, along with our list of the best cordless polishers that you can buy. If you need inspiration, read on!

What Is A Cordless Polisher?

Firstly, let’s just clear up the main point. A cordless polisher is a tool that you can use to smooth down the exterior of your car.

This means removing small damages from it, like dents and scratches. Obviously there is a limit to what it can remove – it can’t magic back in a whole chunk of car that’s been smashed in! But it can get rid of the small, annoying things.

A cordless polisher is, naturally, a polisher that has no cord. It’s wireless, if you will! There is no cable that runs from it to an electrical outlet in the wall.

The clear benefit of this is that you can move easily around your car, smoothing as you please, without getting tangled up in any cables.

A cordless tool gives you the freedom to go anywhere and to move without limits.

However, cordless does come at a cost. We don’t just mean price either! No, the major downside of going cordless is that the tool runs off a battery instead.

This means that you only have so much use out of it, because the longer you use it, the more its battery will run down. Eventually, it’ll cut out and you’ll have to go and charge it.

This means that you can only smooth your car for so long before you have to retreat back to your house and put the tool on charge.

The Best Cordless Polishers

Below, we’re going to look at the best cordless polishers that we think you can buy. When reviewing each, we’re going to talk about a variety of elements, such as their power and their battery life – as well as other features.

Milwaukee M18 Fuel FAP180-0

This cordless model from Milwaukee, not to be confused with the city, is a great choice if you’re looking for a stylish and powerful polisher.

It has a very sleek design, perfectly shaped for easy holding, and dressed in stylish red and black colors.

It has a 3 position bale handle to give you even greater control when gripping onto it.

Another reason that it’s so easy to hold is because it has a very slight weight to it, much less than most other cordless polishers on the market.

Weighing around 2.2 kg in total, when the battery pack is attached, it is one of the lightest polishers you can get – which will make it easy for you to keep up for long periods of polishing, without your arms giving in.

On top of that, you’ll be able to lift it to the higher parts of the car much more easily, without the danger of dropping it from excessive weight and damaging yourself.

The sleek design, along with the fact that it’s cordless, will mean that you can carry it around any part of your car – able to get to every crevice and dent.

And when it does get to the dents? It’s powerful! There’s a great deal of choice with how much power and speed the polisher is going to give out, with the polisher coming with an 8-position variable speed selection.

This goes from low to high, giving anything from 360 rmp to 2,200 opm.

If you don’t know, opm stands for “orbits per minute”. So, at the top speed of 2,200 opm then the polisher is going to be turning around a total of 2,200 times every minute! That’s a lot of spinning, and is guaranteed to get rid of any small dents.

Of course, you don’t have to use full speed. Indeed, it’ll certainly make the battery last longer.

The important thing is that this model gives you a range of choices, meaning that you can find exactly the right speed for the job at hand.

Speaking of batteries, that is a key downside with the Milwaukee M18 – it does not come with a battery pack.

Given that the polisher already costs a reasonable amount, having to pay more for a battery pack on top of that can be quite annoying.

With that being said, at least the polisher is powerful enough to make up for it. The motor has a soft start mode, meaning it eases smoothly into things. On top of that, it has safety features to keep you safe.

After a battery change, it has a line-lock-out specification that will stop the polisher from automatically starting up immediately.

Additionally, it has overload protection to stop it from getting overworked.

Pros

  • Sleek design, easy to hold
  • Dust screen
  • 8-position variable speed
  • Soft start feature
  • Powerful

Cons

  • Doesn’t come with a battery pack
  • Battery life could be better

Specifications

  • Speed: 360-2,200 opm
  • Weight: 2.2 kg when battery pack attached
  • Warranty: 1 year, 3 if you register online

Flex 418099 Cordless Random Orbital Polisher

The big difference between this and the Milwaukee M18 is that this is dual action, which the other was not.

But what does dual action mean for you? Well, it means that the polisher uses a combination of both a circular motion and a spinning motion.

This means that you get the best of both worlds, getting a dual action treatment that is sure to carry the power to remove most dents and scratches very thoroughly.

It also beats the Milwaukee in the orbits department, offering an even higher – and even greater – range of speeds and speed settings.

This cordless polisher boats 2,300 to 7,500 opm. This means that on its highest setting, the polisher is going to be giving you 7,500 full robots every single minute.

That’s such a speed and thrust that it’s likely to get out any small damages to your car body. However, as always, using the highest speed setting is going to drain your battery the quickest.

And that’s a problem with the Flex Cordless, because it’s battery life could be better. If you’ve got a smaller car, then you might manage to get a good go out of a single battery pack before it runs down.

But if you’ve got a larger vehicle, like an SUV, then you’ll probably be having to swap battery packs mid-session.

At least, unlike the Milwaukee, this actually comes with a battery pack – and not just one, but two!

With that being said, the other downside is weight. Although it actually clocks in at a lower weight than the Milwaukee, it isn’t as elegant or sleek, and so can feel a lot more bulky when you’re handling it.

Pros

  • High speed omp range
  • Dual action
  • Comes with battery packs

Cons

  • Batteries could last longer
  • Bulky body

Specifications

  • Speed: 2,300-7,500 opm
  • Weight: 2.1 kg when battery pack attached
  • Warranty: 1 year

Liquid Elements A4000 V2 Cordless Eccentric Polisher

This polisher from Liquid Elements is one of the more affordable ones on the market, and all without sacrificing too much quality.

For one, it’s got a very good battery, which even comes with it in the form of a battery pack.

Listings proudly declare that the battery pack, when fully charged, will give you a full 45 minutes of polishing.

That should be more than enough to go around your car and get any dents out, without having to go back to the house and charge up the battery pack, or swap them out with another.

Sadly, this is probably because the polisher doesn’t have as much power as other polishers on the market. It can only offer, through its speed settings, anywhere from 1,400 to 2,100 opm.

This is nowhere near the orbits that the Flex can manage, but it’s actually very close to what the Milwuakee did – so it’s not all bad.

The other drawback, though, is that it doesn’t have the broad range.

With the lowest setting being 1,400 opm, you won’t be able to adjust the speed and power as much as you like in accordance with the size of work you’re doing.

With that being said, though, it is dual action! Which is a big benefit, because the combination of circular and spinning motions means that you’ll be getting a powerful polish for all 45 of those battery-fuelled minutes.

The fact that it’s dual action will make up a little for the low speed settings, allowing you to get a few worse scratches out.

Pros

  • Dual action
  • Speed settings
  • Great price
  • Comes with a battery pack

Cons

  • Speed doesn’t go very high, plus broad range
  • Heavier than others

Specifications

  • Speed: 1,400-2,100 opm
  • Weight: 2.6 kg
  • Warranty: 1 year

A Guide To Buying Cordless Polishers

Our list is a great start, though there are things that you’re going to keep in mind when you’re finding a cordless polisher that’s best for you. We’re going to go into a few of those to help you!

Pros Of Cordless Polishers

The key one is versatility. If you had a corded polisher and it was plugged into the wall, then you’d only be able to take it so far away from there.

On top of that, you can’t move it about easily, constantly getting tangled up in wires.

A cordless polisher will be able to let you reach high and low, all around the car and in every crevice and underside – doing a complete removal of small scratches.

Better yet, it does all of this without sacrificing the power, because they can offer exactly as much power and opm as a corded polisher.

Batteries

But that’s the downside: they have to run on batteries. Though batteries are a handy source of power, they will never last as long as if the polisher was plugged into the ceaseless source of power that is the electrical outlet.

However, the batteries that we have at the moment are good enough. Most cordless polishers will come with a battery pack or two, but sometimes you will have to buy one separately at extra expense.

The ones you get tend to be lithium-ion based, running 21 volts and 4 Ah (which stands for ampere hours, a measure of the amount of energy in the battery to allow 1 ampere of current to flow for a single hour).

As we’ve touched on in the list, you’re likely to get about 45 minutes of use from one of these fully-charged battery packs.

Packs that give you more will be much heavier, so even they have a downside.

Corded VS Cordless

So, we know that battery packs hold the cordless polishers back from lasting as long as the corded ones – but how else do they stack up against their wired cousin? Well, pretty much perfect.

A cordless polisher will give you absolutely as much power as a corded one, depending on the model.

You can get dual action ones for added power, too. Most will have the same orbit diameter (15 mm) too, allowing for a wider covering area – getting every dent.

Cordless also offers similar speeds and speed ranges, meaning that you should be getting similar orbits per minute to the corded models as well. They’re practically identical in all but battery!

Final Thoughts

There you have it! Cordless polishes offer the versatility that corded ones just don’t. Despite their battery drawbacks, they are every bit as powerful and good as the corded ones.

If you’re thinking of getting one, make sure to look at our buying guide. Know what you want, and think about what kind of dents you might be using it on.

When you have those parameters in mind, have a look at our list of the best cordless polishers and see if any of them line up with what you want! They’re the best on the market, so hopefully they will.
