Angle grinders are following in the footsteps of many traditional power tools in cutting the cord and moving to battery technology.
Many users are embracing the freedom of cordless machines, being able to work anywhere without the need for potentially hazardous and awkward extension cords.
Whilst battery life and power are still significant barriers to some users, battery technology is rapidly improving and cordless machines are increasingly coming up to speed with their corded counterparts.
What is a cordless angle grinder?
Cordless angle grinders are hand-held battery operated tools used in a wide range of industries. These versatile machines can be found in a vast array of applications, from metal fabrication, plumbing, trade, DIY and many more. Powered by inter-changeable and re-chargeable batteries, cordless grinders mostly come in 115 and 125mm sizes, with maximum speeds of up to 9,000 rpm.
Why choose a cordless grinder?
Powered by re-chargeable battery packs, cordless grinders give the user more freedom and mobility, however these advantages are weighed against limited performance and usage life. If you’re using a grinder for long periods at a time, cordless machines probably aren’t the right choice for you. If, however, you’re working in remote areas, multiple sites, or just have a quick job to do; a cordless machine will offer you both freedom and practicality.
What’s the difference between a cordless and electric grinder?
Depending on your abrasive choice and application, an electric grinder will give you consistent and continuous use and is especially suited for heavyy duty applications.
Choosing the right abrasive and good quality batteries is crucial to getting the most out of your cordless grinder. Using specially recommened abrasive products will help prolong battery life and get the best results in your application.
Why battery choice is important
Choosing the right battery for your cordless tool and usage requirements is crucial to getting the most out of your investment. Battery technology is rapidly advancing, becoming more suitably equipped for the heavy demands of an angle grinder. There are three types of battery available, depending on your needs:
Nickle Cadmium (NiCd)
These are entry-level batteries, and are generally the least expensive option. They tend to have a long cycle life, however they are also heavy and have a lower capacity than other batteries for cordless tools.
Nickle Metal Hydride (NiMH)
MiMH batteries are the next step up from Nickle Cadmium, offering increased capacity (running for 2 – 3 times longer per charge). However, NiMH batteries are far more sensitive to temperature, which can be an issue as grinding operations generate a lot of heat and can damage or hinder the battery’s performance.
Lithium Ion (Li-Ion)
These are the best choice in the market for your cordless machine – they are the most light-weight option and have the highest output capacity. Whilst Lithium Ion batteries are more expensive than their Nickle-based alternatives, they are far superior in power, performance and durability.
It’s important to bear in mind that a cordless angle grinder will have different power and battery requirements to other cordless tools. For example, compared to a standard cordless drill the torque required to turn an abrasive wheel at 9,000 RPM is far greater than the twisting force necessary to turn a drill bit. Only with the introduction of Lithium Ion batteries have cordless grinders really come into the market as a serious alternative to electric angle grinders.

Here, Paul answers some of the most common questions asked about abrasives and cordless grinders:
Can I use mini angle grinder discs on my standard cordless machine?
Yes, you can. Use an adaptor to adjust the standard mini quick change back up pad to fit your machine. Thanks to their small size and less power needed from the machine, the mini discs extend battery life considerably.
Will a corded grinder ever replace my corded tool?
It really depends on your usage requirements – if you regularly use your corded tool in heavy applications, the answer is probably no, but that doesn’t mean that a battery grinder won’t be of any use to you. It might not be your go-to machine, but it will always come in handy
How long should I expect my grinder to last between charges?
This depends on the type of work you’re doing with it – if you’re continuously grinding heavy material, then your battery won’t last very long (also depending on the type size of battery you have), but if you’re doing lighter work, using recommended discs and letting the battery cool between uses, then you’ll get much more life per charge.
Can I use a disc rated at 12,250 rpm on my grinder that runs at 9,000?
Yes – running a disc at a lower speed than its maximum capacity is perfectly safe (never go over a disc’s maximum rated RPM). Look for products with a cordless icon to see if they’re recommended for performance on a battery-operated angle grinder.
Why are Aluminium Oxide grains better than ceramic for some products?
Ceramic grains are high-performance options for high-powered machines –they require a large amount of heat and force to break down, release old dull grains and re-sharpen. Battery Powered right angle grinders run at lower speeds and generate less heat and force. Therefore, you need a more friable grain with a weaker bond structure, like aluminium oxide to stay sharp and get a quick effective result.
Do I need more than one battery for my Cordless grinder?
Ideally yes – it’s always a good idea to have a back-up charged and ready to go so you don’t get caught short on a job.

What safety tips should be known before using an angle grinder?
Angle Grinder Safety
Angle grinders combine two dangerous elements together, a high RPM spinning motor with a sharp cutting disc. The following safety tips should always be considered to help avoid serious injury:
Ensure the device is switched off before you plug it in. Before plugging an angle grinder into the power source, make sure that the machine itself is switched off.
Read the manual and understand how it works. Even for an experienced user when getting a new power tool it is always a good idea to read the manual to ensure that you are completely familiar with the modes of operation and the features of the tool. Power tools are inherently dangerous machines, so this is very important.
Use the right grinding disc for the job. It is important that not only that you use the correct disc size for the angle grinder, but also that you use the right type of disc for the material. For example, using a metal cutting disc to cut ceramic and stone may at best wear the disc down too fast, but, at worse, may put you in danger by breaking the material.
Wear the right clothing and protective gear. It is always a good idea to protect yourself by wearing the appropriate safety gear when using an angle grinder. Not only can an angle grinder produce a lot of sparks, but it can also throw up cutting debris. For this reason, it is imperative to wear safety goggles. It is also a good idea to wear safety gloves. Depending on the circumstances and ventilation, it can be a good idea to wear a dust mask. This is beneficial when cutting masonry or ceramics, as in a closed environment these materials can generate a lot of dust. Using grinders in certain situations can also be quite noisy, so ear defenders may also be needed.
Use the grinder correctly. Some people remove the safety guard from the grinder, to make it easier to carry out certain jobs. This is a bad idea, the safety guard is there for a reason and should always be kept it in place. You should also always use an angle grinder with two hands, as they can twist out of your hands if you are not careful. Furthermore, you should inspect a power tool before you start a job and replace any parts before use if they are not in a good condition.
Keep your attention focused. Angle grinders are dangerous tools to use so it is important to keep focused and attentive to the job. Avoid distractions and take regular breaks.

Choosing the Best Angle Grinders—Buying Guide
Read on below to learn more about the different angle grinders and their best uses.
Types of Angle Grinders
There are four main types of angle grinders available, each with its own strengths, limitations, and type of power source. Most angle grinders can either be cordless, corded, gas-powered, or pneumatic.
Cordless Angle Grinders
Cordless power tools do not have the distance limitations of a power cord and allow operators the freedom of using them wherever they want, even outdoors. With battery technology improving every year, some cordless models are on-par, power-wise, with electric models. The only limitation of battery-powered grinders is if users don’t have a backup battery, then cordless grinders will generally only have a little over 45 minutes of run time.
Corded or Electric Angle Grinders
Corded models are one of the more popular types of angle grinders purchased for their power and unlimited power duration. A corded grinder is restrained by its cord, but for bigger jobs, a corded model doesn’t require batteries or the high maintenance needed for a pneumatic or gas power source angle grinder.
Pneumatic Angle Grinders
Pneumatic grinders work by using air pressure from an air compressor. When it comes to power levels, these would come just after gas-powered angle grinders and can be very expensive to own and operate, considering that air compressors have to be changed often because the refills are quite small and don’t hold that much air. One perk to a pneumatic version is that is tends to run longer than a cordless tool and is more powerful than a corded model.
Gas-Powered Angle Grinders
Like most gas-powered tools, gas angle grinders are the most powerful angle grinders available on the market. They are more expensive than other types of grinders and are also heavier. Additionally, gas-powered versions require a lot of maintenance and are not a top choice for smaller jobs.
We hope our review of the best angle grinders has been helpful, whether you were after something for heavy-duty projects or a model with the best safety features.

Tips on Choosing the Right Small Angle Grinders
Before getting to a point of selecting one small angle grinder as the best one for your projects, it would be beneficial to learn what an angle grinder is in more general terms. Angle grinders, also known as side or disc grinders, are portable power equipment used for grinding and polishing. They’re utilized in a wide range of sectors and vocations, including metallurgy, construction, and emergency rescue.
An electric motor, a gasoline engine, or compressed air can all be used to power the angle grinder – or in this case the small angle grinder. For practical purposes, the portable angle grinder is the most widely used and recognized type. Cutting discs having a diameter of up to 115 mm are used in small angle grinders. They’re great for cutting metal, but they rapidly run out of steam when it comes to concrete.
When purchasing a small angle grinder, or bigger kinds, keep the following aspects in mind:Motor powePower sourceRPMArbor size
Angle Grinders of Various Types
Angle grinders are divided into three main categories, each with its own set of applications. To make an informed purchasing selection, it’s critical to grasp the distinctions between each variety.
[add permalink=”Angle-Grinder” count=”9″ lang=”en”]
Cordless Angle Grinders
Angle grinders with cordless power are utilized in a wide range of applications. These grinders may be moved from one location to another without needing to be connected to a power source. When it comes to doing ladder and scaffold-based grinding jobs, cordless grinders are especially useful because there are no trailing wires to provide a trip hazard. To eliminate the worry of a regular mains power connection, it is recommended to pick models with large capacity batteries.
Corded Angle Grinders
In some cases, the guarantee of a dependable power outlet will be necessary, as corded angle grinders can be used as long as they are linked to the power source. Small angle grinders that are corded are generally less in weight than cordless versions. If you’re planning to use your grinder for modest cutting chores on a regular basis, get one with a tiny disc. You should also consider the ergonomics and vibration level of the grinder you’ve picked.
Pneumatic Angle Grinders
Pneumatic angle grinders are suitable for cutting and shaping metal workpieces because they combine performance and durability. This type of small angle grinders is mostly utilized for light-duty operations that need a lot of accuracy. Pneumatic grinders need the use of an air compressor, but they are well-suited to high-precision applications and are far lighter than conventional angle grinder models. Furthermore, some come equipped with throttle levers, allowing for precise control while doing specialized chores like feather edging and speed grinding.
Depending on the discs attached, here’s a summary of the most typical uses for air angle grinders:
- Grinding: Using moderate pressure at an angle, the material will be smoothed to perfection. Surface preparation and material removal are among the activities included.
- Cutting: For precise pipe or metal cutting, smaller wheels are utilized.
- Angle grinders are excellent for sanding woodwork.
- Deburring: Air grinders can quickly remove pestilent burrs or material remnants.
