Bosch Angle Grinders Review

When you buy Bosch you know you are buying quality. This is why they are one of the most trusted power tool brands in the business. Bosch angle grinders are no exception to this rule, so at Wonkee Donkee we decided to test all of their models and pick the best ones. After completing all of our tests it was clear to us that the Bosch GWS18V-45 and the Bosch 1375A are the best Bosch angle grinders available. 

Bosch GWS18V-45 Angle Grinder

The Bosch GWS18V-45 is not just one of the better Bosch angle grinders, it’s one of the best angle grinders on the market period. To begin, the 18V motor packs a huge punch, providing it with more than enough power for even the toughest jobs. This power doesn’t come at much cost either, with staggeringly good battery life for a handheld tool. You’ll be as amazed as we were at how much work you can get done with one single charge of the Bosch GWS18V-45.


In this model, Bosch has produced an angle grinder that fits in the workshop of professionals and home improvement enthusiasts alike. It is easy and comfortable to use, thanks largely to its ergonomic shape and handle position which helps reduce vibrations. It is also one of the safest and the markets too, which is of the utmost importance when it comes to power tools.


The cooling functionality called ‘CoolPack’ is also very good. This technology helps to extend battery life and the life of the angle grinder by stopping the handheld tool overheating. In terms of cordless angle grinders, this is about as good as it gets, making it our number one pick for the best Bosch angle grinders.

Bosch Angle Grinder Buying Guide

The goal of our angle grinder reviews is to provide you with all the information that you need in order to make the right decision and get the best power tool for you. Whether you just wanted to learn more about the Bosch models or if a bit more information about one of their tools we hope that we have helped you find what you need.


However, if you have never bought an angle grinder before or if you are not totally familiar with the language used in specifications of tools then we have got you covered too. At Wonkee Donkee, we like to offer buying advice in the form of buying guides to allow you to learn more about different power tools and what their specifications mean all in one place. So if you want to know more before you buy, below we have a full angle grinder buying guide to help you.


In this section, we will look at the main components of an angle grinder, together with the main features of these components so you can understand what they mean for you. Our goal is to give you enough information that you can buy an angle grinder with confidence, knowing that it is the perfect tool for you.


The first decision you make when you are looking at buying a new angle grinder is whether you are after a cordless or corded tool. The differences and benefits of these two different designs are obvious but we will just go through them quickly. A cordless angle grinder allows you to work anywhere without the worry of power sources, avoiding getting tangled in the cord and access tighter spaces or get a better angle when operating. However, on the flip side, you know that with a corded angle grinder you don’t have to worry about battery life.


Thankfully, as technology has advanced with the right battery you can get superb and extensive performance. It’s not that every angle grinder has embraced the best technology so you need to be selective. While for many, the battery may not seem like the most important component. It is a function that most angle grinders have, obviously besides corded angle grinders. As with many over battery-powered tools around now, it is easily overlooked but when it comes to cordless angle grinders it is easily the most important element of the tool.


What to look out for are lithium-ion batteries, as these batteries have the added benefit of weighing less. If you are going to be holding the angle grinder for extended periods of time, weight is a factor. In addition, lithium-ion batteries tend to be some of the fastest-charging batteries on the market, so you have less time waiting around and can get back to work faster if the battery dies.


When it comes to Bosch batteries there is an added benefit in the fact that they are compatible with most tools. Bosch designs their power tools so that all of them are compatible with a single battery design. This means that they’ll be compatible with a range of other power tools which is why a lot of contractors tend to opt for Bosch power tools over other brands. The peace of mind that one battery can power a range of different power tools reduces the risk of being caught short whilst on the job.


As we’ve just talked about, the weight of an angle grinder, or any power tool for that matter, is vital. One of the great advantages of a cordless angle grinder is that you can take it anywhere and use it to get at really difficult angles. So it would be really counterproductive for Bosch angle grinders to be heavy, stopping you from holding and operating them for an extended period of time due to fatigue.


The best weight range of an angle grinder is really dependant on how long you intend to operate the tool as well as your own physical capability. Some jobs that you use an angle grinder for, such as polishing large surfaces or grinding down metal from welds require you to hold the angle grinder for extended periods of time. You’ll grow to hate having to use an angle grinder if it becomes an endurance event, because the tool is too heavy to manage. It will also make it harder to manoeuvre and get the best angle.


The final consideration when it comes to weight is that typically a heavier angle grinder is a sign of older technology. One of the main focuses of power tool manufacturers has been to reduce the weight of angle grinders. So, to make sure you have an angle grinder that is easy and comfortable to use as well as packed with the latest technology, always look at the weight.


You’ll find that many Bosch angle grinders use brush motors. That’s because they’re a more affordable technology. The brushless motors are actually lighter, and quieter too. But, they are so much more expensive than standard brush motors. Our advice at Wonkee Donkee is that if you can afford an angle grinder with a brushless motor and you will use it regularly then get one. You will notice the difference immediately, with the ability to do more things than a normal brush motor.


However, if you don’ tend to use an angle grinder regularly then a brush motor model will be more than enough. Truthfully, if you are skilled with an angle grinder then you won’t notice that much difference as you’re working, besides the fact that brush models are louder and heavier when operating.

So, which Bosch angle grinder is right for you?

We can’t pick the Bosch angle grinder that is perfectly right for you, as with all power tools it depends on what you need it for. What we can do is give you some ideas and pointers that will help you make the right decision for you allowing you to choose the perfect Bosch angle grinder for you.


In many cases, we’d suggest the Bosch GWX18V because as a general rule of thumb it’s better to have a cordless angle grinder than a corded model. This hand tool from Bosch also tops many of our other top review lists too, so it’s not just Bosch’s best angle grinder but also one of the best angle grinders available on the market today.


Saying that, at Wonkee Donkee we know that there is no one size fits all when it comes to power tools or even hand tools. There will always be some exceptions. In this case, if you are working on really large projects where you will regularly be using an angle grinder then a corded option may be more suitable. Tasks such as having to grind rust extensively or polish large areas can be laborious and stopping to recharge a power tools battery is the last thing you will want to do. In this case, you might want to look at the corded model such as the Bosch 1375A angle grinder as a viable option.


Both of these Bosch models are well priced too. There are some slightly cheaper angle grinders that are similar in quality but when we tested them they were a touch inferior. We’d personally suggest paying that little bit more for that extra quality, but it’s not up to us where your hard-earned cash goes. To see the other options we are on about, check out our best angle grinders guide.


The Bosch GWS18V-45 is a great choice for anyone looking for a cordless angle grinder. Built with a powerful motor, vibration-reducing handle, long battery life and loads of extra features. It is easy and practical to use, even for long periods of time. As with all Bosch power tools you get complete peace of mind that you’re going to get quality. It’s also reasonable on the pocket, so what’s not to love Bosch GWS18V-45 angle grinder?
