7 Best Angle Grinders (2021 Review)

The best angle grinder should be powered by a 700W motor at minimum if corded or, if cordless, an 18V battery that has a capacity of at least 4Ah. Angle grinders are formidable tools and need plenty of power to spin cutting discs or grinding wheels at high velocity. Look for corded models that spin between 11,000-12,000 rpm or cordless angle grinders that spin between 7,500-9,000 rpm. The disc diameter on most common models is usually 115-125mm in diameter, although heavy duty angle grinders can come with discs over twice that figure.

Noise and vibration levels are an important feature to factor in with this type of power tool. Cordless angle grinders with brushless motors are the least noisy with lower vibration levels but they are more expensive, particularly if you include the cost of a battery and charger. The weight of an angle grinder is important too – anything between 1.5 and 2.5kg is acceptable for a 115mm or 125mm angle grinder. And don’t forget about accessories – budget angle grinders in particular are usually packaged with extra cutting or grinding wheels.

I’ve tested out the best angle grinders, from high tech cordless grinders to budget-friendly basic ones, so you don’t have to. Read on to see what I discovered…

Makita GA4530R Angle Grinder Review

Specifications

  • Power: Mains - 720W
  • Disc Diameter: 115mm
  • No-Load Speed: 11,000rpm
  • Cutting Wheels Included: n/a
  • Grinding Wheels Included: n/a
  • Weight: 1.8kg

Makita is one of the most respected tool brands around, and the GA4530R is an excellent example of a professional-quality angle grinder. It’s easy to use, not too heavy and it’s built like a tank.

There’s a good reason why builders and savvy DIYers across the world trust Makita. Their build quality and attention to detail are second to none. This angle grinder has a large rubberised rear grip and a tough power cable. I can see it lasting for a long time, even on a building site.

The 720 Watt, 6 Amp motor spins the cutting discs up to an impressive 11,000 rpm. That’s more than enough power to get just about any job done with a 115 mm disc. Weighing in at less than 2 kg, it’s light enough to use one handed if you’re brave enough.

For two-handed use, there’s an indestructible plastic side handle that you can screw into either side. The thing I like about this handle is the 20° angle. You get a better grip for more precise grinding work, compared with standard right-angle grips.

Another bonus feature found on this grinder is the soft start. For such a powerful bit of kit, it doesn’t feel like it’s going to jump out of your hand when you turn it on. And thanks to the anti-restart function, it’s safe to use as well.

Pros

  • The sort of build quality that you’d expect from Makita. It’s tough, well put together and built to take a beating.
  • Makita have included a lock-off switch. I’m a big fan of these compared to the “deadman” style switch you need to hold to keep the disc spinning. They can tire your hand out quickly and aren’t ideal for long grinding sessions.
  • You get a 2.5m power cable to play with. It’s long enough for most grinding jobs, and the quality of the cable is excellent as well.
  • Makita use labyrinth rings to seal the bearings against dust. Anyone who uses grinders a lot know how much dust they produce, so this is a welcome feature.

Cons

  • Attaching the side handle can be a bit of a pain. You’ll need a long screwdriver to hold the bolt in place inside the handle. Compared to simple screw-in handle on the Bosch GWS 7-115, this one can be tricky.
  • Don’t expect to get a case to store the angle grinder in. It’s a shame the grinder only comes in a cardboard box.
  • If you’re only doing light grinding work, you don’t need a professional-level tool. Save some money and buy a budget grinder, this one’s not exactly cheap!
  • Compared to the cordless DeWalt DCG405N, this grinder vibrates quite a lot.

DeWalt DCG405N 18V XR Cordless Angle Grinder Review

Specifications

  • Power: Battery - 18V
  • Disc Diameter: 125mm
  • No-Load Speed: 9,000rpm
  • Cutting Wheels Included: n/a
  • Grinding Wheels Included: n/a
  • Weight: 1.74kg (excl battery)

US tool brand DeWalt are known for making the best angle grinders, and the DCG405N is a step above the competition. Cutting the cord once and for all, this is a powerful grinder that makes use of DeWalt’s excellent XR battery system.

It’s not just a powerful cordless grinder though. The grip shape is supremely comfortable, and the whole unit weighs just 1 kg without the battery installed. You can lock-off the switch when you need to get the grinder into awkward spots as well.

This brushless angle grinder also features a host of clever safety features. I like the no-volt release to prevent accidental start-ups when a new battery is installed. The electronic brake and clutch are essential for safe operation too.

The 18V brushless motor is ideal for battery use. It can make 69 cuts in ½” steel rebar when used with a 5.0 Ah battery. It doesn’t come with any batteries or one of DeWalt’s excellent TSTAK cases though, which is the case with “naked” tools.

Pros

  • DeWalt have made a quick-adjust blade guard. This is incredibly handy if you need to change your grinding angle a lot. No more searching for a screwdriver every time!
  • You can fit a larger cutting disc to this angle grinder. The extra 10 mm you get from a 125 mm blade can sometimes make all the difference.
  • I’m a huge fan of the locking nut that DeWalt use. They’ve included a knurled grip to the outside edge. This means you can grip it much easier and tighten it better by hand.
  • This battery powered grinder features an electronic brake. Disc overrun is the cause of too many accidents, so this is a safety feature I can’t live without.
  • This is an incredibly well-balanced angle grinder. Once a battery is installed it’s not front heavy which makes it ideal for one-handed jobs.

Cons

  • Compared to the cordless Makita DGA452Z, this angle grinder doesn’t spin up as fast. This one only puts out 9,000 rpm compared to the Makita’s 11,000.
  • Like any power-hungry battery tool, you’re going to need backup. Even with a high Ah battery installed they don’t last all that long.
  • DeWalt have done away with the standard angle grinder spanner, but you still need a hex key. I find them even easier to lose than the larger spanner setup.
  • This is not a tool for the casual DIYer unless you’ve already got a charger and several batteries. It’s a “naked” tool, and for this price it’s better suited for professionals.

Bosch Professional GWS 7-115 Corded Angle Grinder Review

Specifications

  • Power: Mains - 720W
  • Disc Diameter: 115mm
  • No-Load Speed: 11,000rpm
  • Cutting Wheels Included: n/a
  • Grinding Wheels Included: n/a
  • Weight: 1.9kg

Power tool pioneers Bosch have been in the game since 1886. They certainly know a thing or two about making the best heavy duty angle grinder. I was amazed at the power and precision you can achieve with the GWS 7-115 angle grinder.

Starting off with the look and feel of this grinder, it’s surprisingly slimline and lightweight. It’s certainly easy to hold on to and weighs less than 2 kg. Bosch have made use of a clever 20° angle side handle as well for ultimate precision grinding.

Making use of one of Bosch’s brilliant 720 Watt Champion motors, you know this is a tool that’s built to last. Everything is chunky and built for hard work. They’ve included a two-stage safety switch to avoid accidental starts, which is essential for any tool like this.

The motor spins a 115 mm cutting disc up to an impressive 11,000 rpm. There’s a relatively low amount of vibration when in use as well. Just 6.5 m/s², which isn’t bad at all for a corded grinder. I like the fact that Bosch have flattened the gear head. This reduces the overall size and makes it easy to get into tight spots.

If you’re looking for one of the best corded angle grinders from one of the top names in the business, this is a great choice.

Pros

  • Changing the brushes on the motor is an easy process. There’s a quick access port on the back of the grinder when you need to replace worn ones.
  • Some grinders are unwieldy and hard to hold on to. This isn’t the case with this tool. The rear handle is narrow and easy to grip, even if you’ve got small hands!
  • 11,000 rpm is plenty of speed for most jobs. It’s 2,000 rpm faster compared with the DeWalt DCG405N.

Cons

  • You might expect to get a case with a Bosch Professional tool. This isn’t the case here. It comes in a cardboard box, not a hard case to keep everything together.
  • Bosch haven’t thrown in any cutting discs to get you started on a project.
  • Some users have had problems with the power switch and reported that it’s too flimsy.
  • The power cord material is a stiff plastic. It’s not as nice compared to the Makita GA4530R’s soft rubberised cable.

Makita DGA452Z 18V Cordless Angle Grinder Review

Specifications

  • Power: Battery - 18V
  • Disc Diameter: 115mm
  • No-Load Speed: 11,000rpm
  • Cutting Wheels Included: n/a
  • Grinding Wheels Included: n/a
  • Weight: 2.3kg (excl battery)

I’m a huge fan of Makita’s cordless LXT range. The DGA452Z is one of the best cordless angle grinders available right now, and it’s a bit of a beast.

The grip shape is nice and narrow, with comfortable rubberised overmoulding on the rear handle. Once you’ve installed a battery it’s well balanced and doesn’t feel too heavy at 1.3 kg without a battery installed.

The Makita cordless angle grinder has a powerful brushless motor that’s efficient as well as powerful. It puts out a whopping 11,000 rpm, which is incredibly impressive for a cordless grinder. When you pair it up with a high Ah battery, it squeezes every last drop of power and runs for a surprisingly long time.

It features a soft start function, battery gauge and overload protection as well. There’s an anti-restart function for added safety between battery changes. One of the most impressive features must be the automatic speed control though. The internal computer controls the power according to the load conditions, which makes for better cuts and a longer tool life.

Don’t forget that this is sold as a “naked” tool. It comes in a cardboard box without batteries or a charger. If you’re already a Makita user, you’ll have plenty of batteries hanging around already.

Pros

  • Compared with the corded GA4530R, the side handle is a lot easier to install. The bolt is captive within the handle, so you don’t need to fiddle with a screwdriver. It’s great.
  • The gear head is particularly small on this grinder. It feels like you can get into much tighter gaps compared with the DeWalt DCG405N.
  • Featuring an electronic current limiter with warning lamp, the grinder lets you know if your batteries are overheating. It’s essential if you want the tool to last a long time.

Cons

  • I’m not keen on battery powered tools with brushed motors. Compared with the DeWalt DCG405N it’s not as efficient or powerful.
  • You’ll need to keep a few charged batteries close to hand. This is a power hungry angle grinder, even when you use high Ah ones.
  • There’s a fair amount of vibration evident when using an artificial wheel. 8.5 m/sec² is a lot compared to the DeWalt DCG405N’s 4.4 m/sec².
  • The handle is bulky compared with the slimline Bosch GWS 7-115. It’s not ideal unless you have large hands.

Ryobi 18AG-0 ONE+ 18V Angle Grinder Review

Specifications

  • Power: Battery - 18V
  • Disc Diameter: 115mm
  • No-Load Speed: 7,500rpm
  • Cutting Wheels Included: n/a
  • Grinding Wheels Included: n/a
  • Weight: 2.5kg (excl battery)

Japanese tool champs Ryobi have made a name for themselves by producing excellent DIY-level power tools. The 18AG-0 is no exception, it’s a comfortable and budget friendly cordless grinder that is ideal for home use.

One of the best things about Ryobi is their ONE+ battery system. You can fit one of their batteries into almost any king of power tool you can think of. If you’ve already bought into their system, you can power anything from a drill to a lawnmower. And all without the need to splash out on extra batteries.

On first impressions, this is a well thought out and ergonomically designed bit of kit. Ryobi’s patented GripZone technology makes it easy to hang on to and use for long periods of time. The 18V battery system can spin the cutting discs up to a reasonable 7,500 rpm. It’s probably enough for most jobs but not the fastest I’ve tested out.

One thing I really like is the auxiliary handle. It’s supremely comfortable with overmoulded rubber parts that help to keep vibrations down. What makes it even better is the three positions you can choose from. Either side or on top of the gear head itself, meaning you get a bit of extra control when you need it.

Pros

  • The quick release guard holder is the best I’ve used so far. It’s easy to position it wherever you need it, and you don’t need tools. Compared to the fiddly one on the Makita DGA452Z it’s great.
  • I really like the trigger system on this grinder. Most users will probably find it easier to use than the slide switch on most grinders.
  • This is a relatively quiet grinder to use. Compared with the cordless Makita DGA452Z it’s a bit kinder on the ears.
  • Compared with the DeWalt DCG405N, this is an affordable cordless angle grinder. You don’t always need to pay professional prices for capable tools without the power cable.

Cons

  • Even though the trigger is easy to operate, there’s no lock-off feature. You need to keep your finger on it to keep the blade spinning. Not ideal for long grinding sessions or awkward positions.
  • For a cordless angle grinder, the vibration is quite high. 7.2 m/sec² is better than then Makita DGA452Z, but much more compared with the DeWalt DCG405N.
  • Once you’ve added a 4 or 5 Ah battery, it’s a heavy tool. Compared with the lightweight corded Makita GA4530R grinder at just 1.8 kg, it’s going to get tiring after a while.
  • Some users have complained that the batteries don’t last for long. It uses a brushed motor that’s never going to be as efficient as the more expensive brushless model.

Tilswall 860W 4-1/2 inch Side Disc Angle Grinder Review

Specifications

  • Power: Mains - 860W
  • Disc Diameter: 125mm
  • No-Load Speed: 12,000rpm
  • Cutting Wheels Included: 3
  • Grinding Wheels Included: 2
  • Weight: 1.5kg

Tilswall are known for being one of the better reviewed budget tool brands. Their powerful 4 1/2″ angle grinder is no exception. The build quality feels robust, the barrel-grip side handle is solid and safe, and the no-tool guard change was useful.

I really like the soft start on the Tilswall angle grinder. It doesn’t have that brutal kick of torsion in your hands when turning it on. It should help avoid wrist fatigue or even injury over time. For this reason alone, I’m calling it the best budget angle grinder on this list.

It’s not the most lightweight and portable angle grinder. The 3.2 kg weight doesn’t quite make up for the fact that it’s a corded angle grinder. But just because it’s light doesn’t mean it’s not powerful. The massive 860 Watt motor can spin cutting discs up to an impressive 12,000 rpm. Not bad for a budget tool.

Tilswall haven’t skimped on consumables either. They’ve thrown in three thick cutting discs and two heavy duty grinding discs with this angle grinder tool. They look like quite decent quality so I’m sure they’ll last long enough over time.

Pros

  • If you’re going to use a corded power tool, it needs to be powerful. This grinder ticks that box. It spins up fast and has bundles of torque.
  • The 125mm maximum disc capacity is handy. The extra size means you can fit 115mm discs when you need to as well.
  • The 7 Amp motor is stronger compared to the 6 Amp one on the Makita GA4530R. It can spin the blade 1,000rpm faster.
  • Tilswall have included two wheel guards for extra safety. It’s a vital part of keeping safe when using an angle grinder.

Cons

  • Like most of the angle grinders I’ve tested out, this one comes without a case. Everything’s shipped in a cardboard box, which is a shame.
  • Compared with the cordless angle grinders on my list, this takes a long time to spin up. It also takes a long time to stop, which can be a safety issue at times.
  • The quality of the included cutting discs is not great. They produce a lot of sparks and can skip around.
  • It’s great that it comes with two safety guards, but they’re tricky to fit properly.

Einhell TE-AG 230/2000 230mm Angle Grinder Review

Specifications

  • Power: Mains - 2,000W
  • Disc Diameter: 230mm
  • No-Load Speed: 6,500rpm
  • Cutting Wheels Included: 1
  • Grinding Wheels Included: 0
  • Weight: 5.8kg

One of the better budget brands I’ve come across, Einhell make solid and reliable tools for DIYers as well as professionals. Their TE-AG 230/2000 is a full size 9″ or 230 mm angle grinder that is designed for the biggest jobs you can throw at it.

If you need to cut through metal, stone or concrete and a mini angle grinder isn’t powerful enough, go for this beast. It’s big and heavy but puts the rest of the grinders on my list to shame when it comes to power.

For a full-size grinder, it’s comfortable to hold on to thanks to overmoulded grip sections. You can place the auxiliary handle in any one of three positions. It’s a necessary feature on a heavy bit of kit like this.

Weighing in at 5.8 kg, it’s more than twice the weight of the closest mini grinder, but it’s not too heavy for a full size machine. Luckily, it features a soft-start mechanism that keeps the “jerk” down to a minimum as well.

The large 2,000 Watt motor spins the 230mm cutting discs up to a reasonable 6,500 rpm. It’s not much compared to the mini grinders, but more than enough for a tool of this size. If you need a full-size angle grinder but you don’t want to overspend, this is a solid budget choice to make.

Pros

  • The disc change spanner is stowed away inside the grinder body. If you remember to put it back it can’t get lost!
  • I’m always a fan of auxiliary handles that can be screwed into three positions. It gives you that added bit of flexibility to tackle the most difficult jobs.
  • The capability of 230mm grinding discs leaves the mini grinders far behind. Cutting and grinding jobs are completed much quicker with a larger grinder tool.
  • You can change the cutting discs quickly and without tools. Compared to the Makita DGA452Z it should be a breeze!

Cons

  • Don’t expect a quiet and refined tool. This is a loud angle grinder that should always be used with hearing protection.
  • Several users have had issues with the switch. It seems like this is a weak point in an otherwise reliable tool.
  • Some users have complained that the grinder was delivered without a cutting disc included.

Things to Know Before Buying an Angle Grinder

An angle grinder is an extremely versatile tool that can be used for a variety of cutting, grinding and polishing jobs. This is why they are so commonly seen on construction sites, and in auto garages and workshops.

Angle Grinder Usage

Angle grinders work by using rapidly rotating headgear to which you can affix a variety of interchangeable abrasive discs or blades. The fast rotation makes these super powerful tools that can cut through the most difficult of materials, including metal, concrete and stone. However smaller grinders can also be used for more delicate work such as cutting ceramic tiles or polishing metal.

As well as cutting the materials above, an angle grinder can also be used to grind away burrs left after cutting metal with various other power saws. In addition, grinders can be used to clean rust and dirt from metal as well as to polish it. This versatile tool can even be used to remove paint and sharpen tools.

Angle grinder tools can be used with a large range of accessories – e.g. diamond-bladed cutting discs for tile cutting to abrasive discs for sanding, grinding and polishing to wire brushes for cleaning.

Angle grinders are fast and powerful tools. It is important to take great care when using them and always wear appropriate safe clothing including safety glasses.

Angle grinders come in a variety of sizes – the most common are 115mm and 230mm. Most grinders in this review are of the smaller size, since that is perfectly suitable for most home and DIY needs. However if you are cutting large sheet material or slabs then the larger machine would be more appropriate. Make sure you choose the right size accessories for your tool.

The smaller 115mm angle grinder is lighter and easier to use, and is certainly the best angle grinder for beginners. The smaller size also provides a greater level of precision and is most suited for jobs such as trimming tiles, sharpening blades and grinding and polishing intricate metal work.

Safety Precautions When Using an Angle Grinder

Angle grinders are fast and powerful tools and should be used with the utmost caution. Always wear safety googles or a face shield and gloves when using one. In addition, always make sure the guard is properly adjusted for the job you are undertaking.

When using a new wheel, run it for a minute or two in a protected area to make sure it is not faulty or damaged.

Always align the wheel so that it spins away from sharp edges. This will prevent the wheel from catching and throwing the work or causing the grinder to kickback.

Angle Grinder FAQs

How do you use an angle grinder to cut metal?

An angle grinder is the perfect tool for cutting metal. You will need a metal cut off wheel to complete the job. Never be tempted to use a stone cutting blade for cutting metal as this could result in the metal breaking up and fragments flying off. Once you have fitted your blade, secure the item you wish to cut and then use light pressure to apply the angle cutter. The grinder will do the rest.

How do you use an angle grinder to cut tiles?

To cut ceramic tiles, stone or concrete you will need a stone cutting or diamond blade. Diamond blades are quite expensive, but they get the job done and last a long time. If you attempt to cut very hard materials with inferior blades you will get poor results and probably ruin the blade. Diamond blades are available in ‘wet’ and ‘dry’. As the name suggests one type can be used dry while the other needs to be kept wet while in use.

Cutting these materials is the same as cutting metal, but with items such as stone you may have to apply a little more pressure and the angle cutting will take a lot longer.

How do you use an angle grinder to clean, grind, sand and polish materials?

Angle grinders are ideal for cleaning, polishing and grinding. The secret is to use the right wheel for the job. Cleaning rust and dirt from metal can be done with a wire cup brush or wire wheel. Grinding discs are available for both metal and stone. Abrasive discs and sanding discs are also useful for cleaning up and smoothing work.

Flap sanding discs are a particularly useful attachment as they can clean, sand and even grind a little. They are also very long lasting. Flap sanding discs are available in rough and smooth grits and these can provide a very nice smooth finish. Finally you can purchase polishing pads for your grinder to polish both metal and stone.

Can you use an angle grinder to sharpen blades?

You can use an angle grinder to roughly sharpen blades. You should attach the blade to a secure surface with a clamp and then carefully take the grinder to the edge of the blade to begin sharpening. If the blade you are sharpening begins to get hot, stop and let it cool down otherwise you can damage the blade.
