You can use a 4.5-inch disc for this tool and it also has a spindle size of 5/8 to 11 inches. The one-touch guard makes it simple to use.

It is true that a corded tool can sometimes be restricted. However, we like that the cord length on this model is long. It is 72 inches in length, which allows you to easily walk around with the grinder and use it on a variety of projects.

One complaint we could make about this power tool is that the handle could be more comfortable. It is simply made from plastic like the body of the tool without any grips or added comfort. But there is a side handle, which can give you more control. This side handle should be more comfortable since it is made from rubber for good grip and has a specialized pattern. You can also adjust this to two different positions.

A unique feature of this tool that is worth mentioning is the dust ejection system. Just as the name suggests, this feature is able to get rid of any dust and debris that is sucked into the angle grinder. This is great for durability and it can lower the risk of your tool breaking down sooner.

We like some of the safety features of this Dewalt angle grinder. This includes an auto-off feature when the brushes need replacing. This is going to increase the durability of your tool. There is also a paddle switch, which means that the tool will not have accidental start-ups that can cause accidents.

Therefore, if you are looking for a grinder with more power for harder projects, this Dewalt one might be for you. But you will have to be prepared to pay a higher price. This model has a price tag of around $100. But the safety and durability features mean it is a good investment. What’s more, there is a three-year warranty for peace of mind.

By now, you have probably noticed that cordless angle grinders are typically more expensive than corded ones. This is the same with the Makita XAG09Z. It values at around $147 so it is not the cheapest model on the market. But it offers you a lot, including good runtime. You can enjoy having a three-year warranty with this product for peace of mind.

This angle grinder has a BL brushless motor, which runs more efficiently than a brushed one. Indeed, it includes better battery life and you can use it for up to 50 percent longer than with a brushed motor grinder. So, this means more power and less charging time. It is powered by a 18V battery, which you will have to purchase separately.

This model features Automatic Speed Change Technology that Makita is known for. This means that it can improve the performance of the tool since the speed and torque will adjust to suit the task you are completing.

We like the various safety features that this grinder has too. This includes an electric brake that is activated when the switch is released. This is going to stop the wheel from rotating within two seconds. There is also Electronic Torque Control, which is going to stop the motor if the speed stops. What’s more, there is overheat protection and the advanced technology monitors the battery temperature so that it does not damage the product. There are even over-discharge and overload protections.

When it comes to comfort, this angle grinder can provide it for you. The main handle has a pattern to help with grip. There is also a forward-canted handle that you can use for two-handed projects. This gives you more control of your cuts or polishing, as well as helping left-handed users. The good thing about it is that it is removable so you only have to use it when you want to.

In addition, this angle grinder only weighs 4 pounds. This makes it a lightweight tool to use and it can easily be used over your head. You should also be able to use the grinder for longer since it is lightweight. You will need to work near a power outlet since it is a corded model.

The Metabo HPT grinder is designed to be budget-friendly. You can pick up the G12SR4 model for around $40. But we think that it is great to still have some safety features than other budget models do not. For instance, there is a slide switch to quickly turn the tool off when you need to.

We like that you can get more than just the grinder with this one. You have a carry case, which is good for transportation. You also receive five grinding disks, which is going to allow you to work on many projects. When one is finished, you can simply swap it out for another one without having to purchase more.

A good safety feature included on this Dewalt tool is the blade brake. This is going to engage when the paddle switch is released. Therefore, your power tool is going to stop quickly and accidents can be avoided.

When it comes to ease-of-use and comfort, this grinder is pretty good. It is lightweight at 3.75 pounds and it has a side handle that can be adjusted into two different positions. The comfort on the main tool could be better but you can still have more control thanks to the second handle.

A lot of manual labor can be time-consuming. The good thing about using power tools is that they can get the same job done in half the time. Indeed, this same principle applies to angle grinders. They are a tool that allows efficiency when you are working on a project. Plus, you can often do a better job.

What to Look for in an Angle Grinder

You will soon discover that there are hundreds of angle grinder models out there to choose from. Indeed, they are all going to be different and some are better than others. We have some key features you should look out for when you are choosing your favorite tool.

A High Wattage

The power you need will really depend on the tasks you plan to complete with an angle grinder. But, as a general rule of thumb, it is better to choose a model with a high wattage. This is going to ensure that you have enough power for cutting, grinding, sanding and polishing. You will also be able to work with tougher and thicker materials when you have a high wattage angle grinder.

You should also pay attention to the rotations per minute. This is going to let you know the speed of the abrasive grinder. Around 10,000 to 12,000 is preferable for most tasks.

The Right Disc Size

When you are shopping for an angle grinder, you will soon discover that there are different disc sizes available. If you have never owned this tool before, you may be confused on the best size for common jobs.

Often, you will find sizes from 4.5 inches up to 9 inches. Most jobs only need a disc size of 7 inches and lower. This is going to suit most applications that an angle grinder is used for and you will find that 4.5-inch discs are popular. Be aware that sometimes the disc size will be listed in millimeters. This means that the disc sizes can vary from 115 mm to 230 mm.

If you have a task that requires larger cuts, this is when you can increase the disc size. Think about the work you want to do with this tool and the depth you want to achieve with the cut. This can help choose the right disc size.

An Anti-Kickback Feature

When you are working with an angle grinder, your safety should always be a priority. You should be wearing suitable clothing, ear protectors and protective eyeglasses. But you should also look for models that have an anti-kickback feature.

This feature is very important and it is going to lower the risk of a serious accident happening. It is able to detect when your angle grinder is not working properly and if it has become jammed. The feature will then stop the grinder right away to prevent you from getting hurt.

A Disc Guard

Another safety feature you want to look for in an angle grinder is a disc guard. When you are cutting through different materials there can be pieces of debris that fly up at your face. Of course, this can be dangerous and this is why you wear protective eyeglasses.

But a disc guard is also going to keep you safe. Its purpose is to keep sparks from flying at you, as well as small pieces of debris and dust. In particular, you want to look for a model that has an adjustable disc guard. This is going to allow you to change its position to suit the way you are cutting the material.

Overload Protection

You may consider purchasing a cheaper model of an angle grinder. After all, they are going to be used continuously for hard jobs. Of course, if they are cheap enough, you will not have a problem replacing them all the time. But over time, this does add up and you can spend a lot of money on this tool.

Instead, you can look for a model that has overload protection. Often, it is when an angle grinder overheats that it can break and wear down over time. But if your model has overload protection, this is going to alert you when the motor or battery is starting to work too hard and overheat. Instead of allowing you to keep going, it is going to shut it down. This is going to prevent damage to your tool that can shorten its lifespan.

So, you may spend more money on a single angle grinder when it has overload protection. But the purpose is that your tool is going to last longer and be the most efficient choice for you over time.

Variable Speeds

You will find that there are some models that offer a single speed to work with or have variable speeds available. A lot of cheaper angle grinders will only have a single speed. For basic projects and standard tasks, this might suit you.

Indeed, when you have the options of different speeds, this is going to allow you to work at a comfortable pace for your project. For instance, if you have intricate work to do, lower speeds can give you the precision you need. But if you want to cut through tougher materials a faster speed may be better for this task.

A Slow Start Feature

If you are new to using angle grinders, you may want to look for a model that has a slow start feature. Just as the name suggests, this means that the grinder will start slow and the motor will gradually increase to full speed. This can be more comfortable to work with and stop it from going to full power straight away and jolting in your hands.

A Paddle Switch

You may see that a model has a paddle switch or a dead man’s switch. This is a beneficial safety mechanism that means the grinder must be held by two hands. It is found on high-tech grinder and models that are more expensive. But it can mean that if you start to lose control and let go of the switch, the grinder will stop operating for your safety.

Other Aspects to Consider

You can choose the most expensive angle grinder on the market with all the latest technology and additions. But you still have to make sure that you like the tool in order to make good use of it. Here are some other aspects to consider before you rush out to purchase an angle grinder.

The Handle Material

Of course, you are going to grip the angle grinder with the handle. This means that you have to exam every model and find the best one for your hands. You want it to be ergonomic and easy to grip.

The material for the handle should also be durable. For instance, if the tool uses cheap plastic, this might start to bend or it may even break after heavy use. After all, an angle grinder is a tool for hard tasks. So, you want to ensure that it is solid and durable.

In addition, it is beneficial to choose a model that has an adjustable handle. This is going to allow you to adjust it to suit your hands and make cutting or polishing a lot easier. Sometimes, you may want to use both hands and for other jobs, you can use one hand. With an adjustable handle, this is going to be a lot easier to adapt.

Anti-vibration features are another aspect to consider when it comes to the handle. This is going to help prevent hand arm vibration or HAV. This is the uncomfortable sensation you can feel when you are using a power tool that has a strong vibration. It can spread up your arms, shoulders and back. Over a long period of time, it can lead to weakness.

The Weight

At the end of the day, you want an angle grinder that is easy to use. Often, this is going to be down to the weight of the tool. If you choose a design that is heavy, this can mean you cannot use it for long projects without taking a break due to fatigue. A good weight is around 3 to 5 pounds.

A heavy tool might also cause muscle stress and tire out your shoulders, arms and back. Over time, this might become painful. It Is best to choose a model that is lightweight and ergonomic. This is going to make it comfortable to hold and allow you to work much longer without feeling sore. Ultimately, you will enjoy more control and better results with your project. This includes cleaner cuts and polishes.

The Warranty

When you are looking at different angle grinder models, be sure to check out the warranty. Tools that have long warranties are often made of stronger and more durable materials. Indeed, this means that if something goes wrong with your model, you will not have to purchase a new one. Instead, you should receive another tool for free from the warranty.

With a long warranty, you can enjoy peace of mind and know that you have invested in a good tool. In particular, you may see popular brands offer 3-year warranties on their tools. But there are some that can offer up to five years, which is advantageous and good value for money.

The Brand

There are a lot of brands out there that are offering power tools such as angle grinders. Indeed, a lot of professionals and DIY enthusiasts prefer to go with a brand that they already know. This can offer you peace of mind especially with lower costing tools. There are some brands that you can depend on more than others. Some popular ones you can choose are Bosch, Dewalt, Makita and Milawaukee.

Corded vs Cordless Angle Grinder

One feature that we have yet to touch on is whether you should choose a corded or a cordless angle grinder. Indeed, this is going to be a huge decision to make when you are deciding on the right tool. There are advantages and disadvantages to both options. You need to choose the most important facts for you. So, here are the differences you should think about when you are tool shopping.

Corded Angle Grinder

There are many advantages to choosing a corded angle grinder. Often, due to being powered by electricity, this tool is going to offer more power and better speed. You can enjoy continuous power without interruption. This is going to be preferable when you are working on a difficult or long project.

The obvious downside to a corded model is that it can limit where you work. You are always going to need a power outlet and you may not be able to use your tool on the road. Some models also have shorter wires than others so that can impact the way you work and how much freedom you can enjoy.

Cordless Angle Grinder

When somebody mentions an angle grinder that runs on a battery, you probably do not think it is really up for the job. Perhaps this was the case some years ago. Now, modern technology means that cordless angle grinders are better than they have ever been before.

One of the main advantages of the cordless angle grinder is that they are so convenient to use. Since there is no wire, you can use it anywhere without worrying about a power outlet or running out of wire. In particular, you can work freely outdoors.

To ensure you enjoy good power with a cordless angle grinder, it is best to pay more for a high capacity battery. This is going to last longer. In particular, you want one that is 5.0ah or above. You also want to look for modern technology such as a brushless motor.

Of course, the big downside about the cordless models is the runtime and constant charging. Your tool will run out of battery and likely have to be charged for several hours before you can use it again. This can be annoying if you are working on a big task.

You also have to consider that a cordless angle grinder might not be able to deliver the power you are looking for. If it does, it can come with a very high price tag. This is something that you will have to be prepared for and think about whether this is going to be within your budget or not.
