An angle grinder is the right power tool to cut & grind metal, brick, concrete, stone & tile. It’s essential kit for trade professionals & DIYers alike.
There are numerous specific jobs, made easy with an angle grinder, such as removing mortar ahead of repointing brickwork, cutting tiles or sharpening tools (Eg: lawnmower blades).
Choosing the right model, without the latest advice, is time-consuming & can be expensive. And while the best angle grinder makes light work of numerous tasks, the wrong model only frustrates.
What is an Angle Grinder?
An angle grinder turns an interchangeable disk at a speed of up to 12,000 rpm to cut or grind. There are different sizes, defined by the disk diameter.
The smaller models (115mm or 125mm) are easy to handle, precise, lightweight & cost less.
Taking a step up in size, the 230mm models have a deeper cutting depth but are heavier and more expensive.
The Best Angle Grinder 2023
Both corded & cordless angle grinders are a match for most jobs. The top choices are effective, powerful & easy to use.
For site work and most jobs around the home & garden, a cordless model is the right choice. Good battery power tools are both powerful and convenient. There are, however, a couple of negatives, runtime & price.
Limited runtime is easily fixed by a second battery. And while the initial outlay is higher for cordless tools, once you own a couple of batteries, everything gets cheaper.
Along with a decision on the size and whether or not to cut the cord, there are a number of details to consider including power, control, vibrations, noise and important features such as an electric brake & brushless design.

What Can I Use an Angle Grinder For?
An angle grinder can be used to cut & grind Metal, tiles, masonry & more. It makes numerous tasks doable. Here are the top 8 jobs where we reach for an angle grinder…
1. Cutting ceramic tiles, stone & concrete
Use a cutting disk that’s recommended for the material you’re cutting. While a general masonry disk is ok for concrete, make sure you use a specialist blade for porcelain, ceramics, granite, marble etc.
Diamond-tipped disks will cut faster & last longer, although do cost more.
2. Remove old mortar prior to re-pointing
A masonry mortar raking blade makes light work of removing old mortar. The superior alternative is to use a mortar rake (which looks similar to a drill bit) in an angle grinder. This avoids damaging the edges of the bricks & produces less dust.
3. Wall channelling for cables & pipes
Easily cut channels in plaster, cement and brick to run cables & pipes.
4. Strip paint back to bare metal
Rather than spending hours sanding paintwork, a good quality stripping disk will remove paint without damaging the metal. Perfect for car restoration.
5. Cut bars, rods & bolts
Secure one end of whatever you’re cutting & slice down with a metal cutoff disk/blade. So much easier than a hacksaw!
6. Grind, shape and blend metal
An angle grinder is the right tool to clean up edges ahead of welding and again to blend a welded joint. Plus, it’s good for shaping almost any metal.
7. Remove rust, clean & restore metal
A wire brush attachment will quickly remove rust, dirt & even set mortar from any metal surface.
8. Sharpen blades
Clamp the blade firmly & use a metal grinding wheel to quickly sharpen tools such as lawnmower blades, axes, scrapers and spades. Concentrate on holding the grinder at a consistent angle with even strokes.
Can I use an Angle Grinder for Polishing?
No. Although some review sites recommend polishing with an angle grinder, the speed is too high & it will strip paint. Adding to the confusion, there are a number of third party accessories advertised as polishing kits for angle grinders. While these may be okay for polishing concrete, don’t use them on paintwork.
Your best option (aside from a dedicated polisher) is to use a random orbital sander with speed control & the right attachment.
What Else Do I Need to Know?
Choosing the Right Angle Grinder
There are numerous details to look out for when choosing the right model, here’s a quick summary of what’s important.
How deep can an angle grinder cut?
A 115mm (4.5”) angle grinder will cut to a maximum depth of 30mm, while a 125mm (5”) will give you 38mm. The larger 230mm (9”) will cut to a depth of 64mm.
The 230mm option is the right choice for deep cuts through stone & concrete, but they’re heavy & expensive. For most jobs, a 125mm angle grinder is the best option – Easy to handle, precise, lightweight, safe and much cheaper!
This safety feature is standard on more expensive models. The slow start prevents recoil and makes for an accurate and safe cut. It’s good to have on 125mm models and we consider it essential on large angle grinders, where the kick-back can be significant.
Vibrations & Noise
Especially if you plan to use your angle grinder for long periods of time, choosing a model with a low vibration score can make a meaningful difference to user fatigue. Noise is also important in this regard, although good ear protection is a must regardless of which model you choose.
For corded models, a decent length cable and therefore reach is super important.
Dust Extraction Hood
Depending on what you’re cutting, there will be a significant quantity of fine dust generated. In some cases, this cannot be helped but there are occasions where attaching a vacuum makes for a quick clear up and a healthier working environment.
A brushless motor is more efficient, more controllable and best of all, it lasts much longer than a conventional electric motor. Power tools with a brushless motor do cost more. However, their longevity makes them a better investment – saving you money in the long run.
How to Use an Angle Grinder Safely
Used correctly, an angle grinder is safe and easy to use. However, it’s well worth reading through the instructions to fully understand your model’s specifics.
Each and every disk that you buy will have a maximum speed, which should be clearly marked. Make sure the top speed of your angle grinder does not exceed this. Disks used above their recommended speed are liable to shatter.
PPE is a must. Goggles, ear protection, dust mask, gloves and no loose clothing may sound obvious, but they’re super important here. Taking sensible precautions will make for a quick & safe job!
