Work With Ease and Comfort With the Best Cordless Angle Grinder

When most workshop guys think about grinders, they picture the hand-held angle grinder. This multifunctional power tool can be used for many tasks, including cutting iron tubing to repair a damaged valve, carving wood to make furniture, tile cutting for a backsplash, and cleaning grout between tiles.

With technological advancement, professional power tool usage is rapidly shifting to cordless power, and as a result, cordless angle grinders are becoming more popular. The ability to work autonomously from a steady power source is highly desirable. It means you aren’t bound to wires or power cords and can readily access difficult-to-reach workplaces. Whether working with wood, metal, or stone, an angle grinder wheel will make your life significantly easier.

Finding Your Next Cordless Angle Grinder: A Buyer’s Guide

When it comes to purchasing a cordless angle grinder, everyone has different requirements. Some people prefer their grinders to be as strong as possible for heavy-duty work, while others prefer them to be ergonomic and comfortable to work for extended periods. You will need to consider these things to determine which grinder is ideal for you. So, here are some features of a cordless angle grinder and how they affect performance.

Disc size

Angle grinders are available in various sizes, each identified by a number representing the largest diameter of grinding disc or wheel that it can manage. A 4, 4.5, or 5-inch disc will work for the majority. Since bigger discs might be cumbersome or time-consuming, smaller sizes and weights are preferable for DIY projects.

In industrial settings, professionals typically utilize larger discs (up to nine inches) when cutting through thick chunks of material. Discs larger in diameter require grinders that can withstand greater cutting forces. This means you’ll use a heavier tool that’ll wear on your hands faster than a compact angle grinder.


The rpm of an angle grinder is the standard for describing its speed (rpm). Some powerful grinders can reach speeds of 12,000 rpm, while most operate at a lower range of 5,000 to 10,000 rpm. But, the rpm number is under “no-load” conditions, which means the disc is not grinding or cutting anything but is simply spinning in the air. When the disc starts cutting or grinding, the speed drops dramatically.

A higher rpm indicates that the tool is capable can cute material with greater ease and speed, but there is an increased risk of injury due to the disc’s potential to rupture as it heats up at faster speeds. Pay attention to the disc’s maximum supported speed and use the appropriate disc for the job. For instance, if you run a disc that is only supposed to withstand 7,500 rpm at a quicker speed, it may shatter and send pieces of the grinder wheel flying.


The power output potential of angle grinders is measured in volts (V) and amperes (A) (amps). The power of a cordless angle grinder’s battery is measured in volts. Most cordless models have 18-volt or 20-volt batteries, but some have 7.5-volt or even 24-volt batteries. Most cordless power tools have a “magic number” of 18 to 20 volts, which is the best mix of price and usefulness.


The angle grinder’s guard is a very important safety feature covering half of the disc. Its job is to protect the user’s hands by stopping sparks and other debris from flying at them. It also keeps surfaces from getting damaged when working in tight spaces.

The guards on some angle grinders are movable, whereas, on others, it is permanently attached. The adjustable model is preferable because it can shield the user from projectiles in either direction and is useable with either hand. But, if the bolts aren’t secured, a removable guard could come loose. In contrast to removable guards, fixed guards are more secure and won’t fall off using a grinder.

Soft start

Angle grinders might recoil slightly on starting up because they are quick, strong tools. This is especially true if the wheel is big and heavy. The motor’s recoil can cause the angle grinder to jump in the user’s hands, leading to possible serious injury. Soft-start technology decreases the output power to the motor initially, gradually rising until the grinder is fully operational. This power regulation reduces the jolt to the user’s arms and wrists and keeps the grinder from recoiling during start-up, improving safety.

Best Angle Grinder Buyer’s Guide

An angle grinder is normally not one of the first power tools you turn to when you need to perform a task for DIY purposes, so this buyer’s guide is a refresher course on what to expect from the best cordless angle grinder.

For starters, we will not be answering any silly questions like “Is an angle grinder just like a chainsaw?” because the answer to that question is obvious.

What Is An Angle Grinder?

Also referred to as a cut off tool or a side or disc grinder, an angle grinder is a power tool you can use for many jobs. Grinding, cutting, and polishing different kinds of metallic and concrete materials make up the primary functions of an angle grinder.

Sometimes included on angle grinders are adjustable guards and side-handles for easier operation. With the help of a special sanding disc, some best angle grinders can also be used as sanders.

Putting it in plain terms, an angle grinder is an essential tool to have depending on the DIY projects you wish to take on. If you have sheets of metal laying around in your garage and you want to make backyard ornaments out of them, then that is the time to give the best angle grinder a call.

Are Angle Grinder Discs Interchangeable?

Here is a word of caution to remember; if a manufacturer doesn’t specifically note a certain type of blade that can be used for its grinder, chances are likely that the grinder doesn’t support that blade.

Now, you could play around with a grinder and make adjustments to bolt a blade into place, but I would not recommend doing that because of safety reasons.

Can I Use a 4-inch Blade on a 4.5-Inch Angle Grinder?

The tooling of both 4-inch and 4.5-inch angle grinder blades is not interchangeable, at least not in the sense that it will be useful for you.

Most 4.5-inch blades won’t fit on a 4-inch best cordless angle grinder, and even if some do, it will likely run too fast and stop working after a period of time. You will have a better time fitting 4-inch blades on 4.5-inch grinders as those often work, but those blades are too small to function the way you want them to.

How Do I Change the Blade on My Best Cordless Angle Grinder?

Changing the blade on your best cordless angle grinder only takes a few steps.

  • The first step is to remove the battery from your cordless grinder. Never skip this first step because otherwise, you will always run the risk of accidentally turning the grinder on while removing the blade.
  • The second step is to take a screwdriver and remove the blade guard. By doing this first you will have an easier time removing the blade itself. Not all angle grinders are the same in design, so take note of how all parts of your grinder are held together.
  • Press and hold in the blade lock button of the grinder for the next step. While this button is being held, turn the grinder upside down so that the grinding wheel faces up.
  • Use your free hand to turn the wheel. If the wheel won’t turn, then it is locked.
  • If the wheel turns then press and hold in the blade lock button again.
  • Steps four through six involve you using a wrench to turn the arbor nut counterclockwise, using a vise grip to loosen the arbor nut, and then finally lifting off the old grinding blade after the arbor nut is removed. To break this down in one sense, it is like fixing a broken wheel on a bicycle.

What Are the Different Types of Blades for Angle Grinders?

A single type of blade cannot perform every single kind of job that you want it to when using an angle grinder.

In some senses, you have to treat an angle grinder like a Swiss Army Knife (hey, you could read up on the best Swiss Army knives while you’re here!). When a certain task calls for a certain type of blade, you switch to that blade.

Grinding Blade

First, we have the grinding blade. This is the most common angle grinder blade used at home but it is used minimally in construction jobs.

The grinding blade is one of the thickest blades, conforming to the thickness of materials like metal. The grinding blade is often used for metal fabrication and welding to smooth out the rough edges that come out of a welding session.

Flap Blade

The flap blade is very similar to that of the grinding blade, with the only addition to this blade being the sandpaper on the bottom of the flange. If you are in that mode of sanding materials, this sandpaper attachment is ideal.

In case you lose a grinding blade, the flap blade can work just as well during any grinding procedure.

Cutting Blade

Compared to the grinding blade and the flap blade, the cutting blade is very thin. You use a cutting blade when you cut through thick materials like metal because of the power and pressure that angle grinders normally provide.

Because of the thin layer, the cutting blade relieves the user from using much force. You can also use the cutting blade for grinding, and it can smooth over rough edges of a material if you need it to.

Diamond Blade

Diamond blades have rigged grooves on the outside edges. The diamond blade is designed to be used on ultra-thick surfaces like stone, concrete, and marble tile for masonry work. The grooves are designed to catch the resistance of the angle grinder against thick materials that may be reluctant to cooperate.

Wire Wheel

Last but not least is the wire wheel, which is made out of either stainless or carbon steel. It is used to clean off material before you start a welding session. Metal surfaces will be smoothed out by the small wires that make up this blade.

Can a Wood Blade Be Put On an Angle Grinder?

Many angle grinders are simply not designed to handle tasks related to cutting wood.

Unless you buy an angle grinder like the one KIMO provides, you can’t just force a grinder to act as a wood cutting tool. Angle grinder blades are mainly meant to cut and grind thick materials due to the intensity of the pressure.

Though, saying that, you might get lucky enough to find cutting discs to cut wood that fit your grinder! Check these out:

There are other power tools out there that can safely and efficiently cut wood. With the exception of the KIMO grinder, most angle grinders are too powerful to properly cut wood.

How Often Should I Clean My Grinder?

It is important to take good care of your power tools! Any tools that are allowed to get dirty and gather rust are tools that become unreliable after a long period of time.

The same thing applies to the best cordless angle grinder.

battery, operated, angle, grinder

How often you should clean your angle grinder depends on how often you plan on using it. How many DIY projects do you have lined up for a week that require the use of an angle grinder?

In general, you should clean your angle grinder right after you use it. At the very minimum, you should clean it twice a week especially if you will use it frequently throughout the week.

  • Editor’s note: This is sound advice… But we never clean our tools and if you get a quality tool like the Milwaukee grinder, I don’t reckon you need to. Ours is covered in grease and all sorts of gunk and it’s going strong, even after all these years

Are Angle Grinders Safe?

Angle grinders are generally safe power tools, but they can become dangerous if you are not careful with them.

They generate sparks, and whenever you begin work with one make sure your work area is clear of any debris and flammable materials. Areas that have grain dust or combustible dust accumulation should be avoided.

If you intend to offer a professional service that involves an angle grinder, there are safety precautions you will need to take. You have to use the correct wheel for the size and speed of the grinder.

Before using an angle grinder, it must be checked for cracks, defects, and wear. Any discs that are worn must be replaced.

Let the grinder reach full speed and warm up before you use it and let it make a full stop after you are done using it. Common sense moves such as these are mentioned in OSHA’s document on angle grinder safety.

Do Volts and Amps Matter?

No, they really don’t matter.

Now here is the long answer. The amount of volts a tool has is only mentioned on battery-powered tools.

amps will either mean more power (in other words, power you get out of the wall equals volts multiplied by amps), or a less efficient motor (power out of the wall that just generates heat isn’t useful).

Since we’re discussing cordless grinders only, volts and amps are really irrelevant.

A grinder with more volts and amps does not make it a better grinder than others.

You should aim to buy a grinder that draws at least 5 to 9 amps so that it can handle all the various types of wheels and accessories. However, you should consider how fast an angle grinder operates and how safe it is before focusing on its power.

battery, operated, angle, grinder

So, What’s the Best Grinder Then?

Breaking everything down, if you had to choose right away which best angle grinder to buy, I would recommend you get the Milwaukee 2780-20 M18 Fuel grinder first.

It isn’t the cheapest grinder on this list, but it is the safest, most durable, and most flexible grinder of them all.

Overall, you can’t go wrong with any of these listed grinders as they are all well under 200 in price, which will make your wallet happy!

Ridgid 18V 4 1/2-Inch Cordless Angle Grinder R86047

Ridgid is coming in strong this year with a fresh batch of updated tools and among them is an updated Ridgid 18V cordless 4 1/2-inch angle grinder. We’re going to break down the key details and give you a first-hand look at what makes this grinder worth considering.

Ridgid 18V Cordless Angle Grinder Performance


There’s a lot of debate in the tool industry over paddle triggers vs slide switches on angle grinders. I tend to prefer a paddle trigger simply because I feel like I have greater control of the tool but that’s just my preference. On the other hand, Kenny likes a slide switch.

For this model, Ridgid goes with a large paddle switch that spans the majority of the grip. This gives you the opportunity for multiple hand positions to best suit your needs. Just like other paddle switch tools, there’s a spring-loaded safety for added security during transport.

Once you activate the paddle switch, the Ridgid R86047’s brushless motor spins its 4 1/2-inch grinding wheel up to 9,000 RPM.

Let’s Talk Power

Ridgid doesn’t provide an exact corded equivalent for this angle grinder, but from our experience, it feels and performs very similarly to a 9-amp model. During our testing, we were able to really put some good pressure on it, but it’s not too difficult to slow it down compared to larger cordless angle grinder options.

In terms of application, the Ridgid R86047 is really helpful for light to medium-duty applications such as knocking off rust/paint, polishing, and cutting frozen nuts and bolts. It can reach into some of the tougher applications, but those are the kinds of things you want to move up to a larger, stronger class for the best productivity.

Ridgid 18V Cordless Angle Grinder Design


Overall, we really like the ergonomics of this angle grinder. The rubber overmolded grip section is slim and very comfortable in my hands.

Its 5.8-pound weight (including a 4.0Ah Max Output battery) is very manageable and similar to corded small angle grinders.

From tip to tail this angle grinder measures 13.3 inches. While it’s not labeled as a “compact” tool, it is highly maneuverable and excellent in tight spaces.

Electric Brake

Ridgid includes an electric braking mechanism that quickly stops the wheel’s rotation in a matter of seconds once you release the switch.

On Guard

One nice thing about this grinder is the simple tool-free guard adjustments. To rotate, simply press down on the spring-loaded button and move it into the position that keeps you from getting a spark shower.

One thing to note is that there’s no cut-off wheel shroud. The guard that comes with it is perfectly capable of pulling double duty, and it’s not unusual for small angle grinders to only include one style.

Accessory Changes

One thing I really love about this angle grinder is how Ridgid simplified the flange nut. There’s a built-in folding tab that flips up to give you a better grip and loosen/tighten by hand. We love any option that lets us leave the spanner wrench in the toolbox.

2-Position Side Handle

As with most grinders, the Ridgid R86047 has a 2-position forward assist handle. It gives you a much more stable grip as well as helps to dampen some of the vibrations felt during use.

Ridgid 18V Cordless Angle Grinder Price

The Ridgid R86047 retails for 159 as a bare tool at your local Home Depot or online. It includes the tool, type 27 grinding wheel, guard, side handle, and manual.

Ridgid backs this grinder with its lifetime service agreement when you register within 90 days of purchase.

The Bottom Line

After using the updated Ridgid 18V cordless angle grinder, it’s pretty hard not to like. It’s a great fit for lighter jobs and tight spaces when the size, weight, and power of medium and large angle grinders are overkill.
