Angle grinder and bench grinder, both are grinders, but some common differences have made those different from each other. Because of those differences, angle grinder may not be perfect for the works in which bench grinders are perfect. The opposite is true too. An angle grinder vs bench grinder comparison may make this easier to understand for you. Let’s discuss the main differences between angle grinder and bench grinder.
Angle Grinder vs Bench Grinder
Portability: The big difference between angle grinder and bench grinder is the portability. Angle grinders are extremely portable where bench grinders are tough to take one place to another. The weight of an angle grinder is below 7-8 pounds. Only a few heavyweight angle grinder cross the boundary of 10 pounds. On the other hand, most of the bench grinders are more than 20 pounds and at the same time, 8 inch bench grinders go up to 40 pounds.
This difference of weight has an effect on the portability of both the tools. In case of an angle grinder, we have already seen that these are not too heavy. As a result, these tools are easily portable. On the other hand, bench grinders are not much portable because of the weight.
This portability of the tools has an impact on the way of working with the tool. Angle grinders are light in terms of weight. As a result, the user can hold the tool with hands and use it without any problem. But bench grinders can’t be used by holding it with hands. You should keep the tool on a flat surface and then use the tool. That’s why the tool is called as bench grinder.
During the time of using an angle grinder, you will get the advantage of controlling the tool itself as you are using it by holding in your hands. But when you are using a bench grinder, you have to control the workpiece at the tool should be kept somewhere and you will have to use your hands to hold the workpiece. So here the differences of portability and the ways of using the tool can be seen easily. It establishes a strong point in angle grinder vs bench grinder debate.
Design of the tool: As the ways of using these two types of tools are different, the design of the tool is obviously different. Angle grinders are designed such a way so that it becomes easy to hold and handle the tool. The body of an angle grinder is designed in such a shape that the user can hold it with a comfort grip. To reduce vibration, angle grinders have extra space for a support handle.
On the other hand, the bench grinder is designed with a base so that the user can easily keep the tool on a flat surface. This base of the bench grinder also works for reducing vibration.
Types of works: Angle grinder and bench grinder, both can be used for almost same type of operation. But there are some differences. As the tools are of different design and the way of working is different, there must be some differences at least in the field of perfection. Yes, there is. Let me show you.
Bench grinders are perfect for sharpening. If you want to sharpen any tool or tool blade, bench grinder will be perfect. You can control the blade by your hands and sharpen the areas you want. Besides sharpening, bench grinders can be perfectly used for shaping. Sharpening with an angle grinder is a little bit tough. So if you are a beginner, you will face a problem.
On the other hand, angle grinders will go perfect for cutting. As you are able to handle and control the tool perfectly, you will be able to cut any piece of any shape from a big piece. You will be able to perform grinding perfectly with the help of angle grinder. You may be able to use a bench grinder to cut thin and narrow objects, but angle grinder is always better for those, even for objects of any size and normal depth.
Bench grinders can also do polishing but the polishing surface should be small. All you have to do is to add a polishing wheel or brush wheel. As you will have to control the workpiece by your hands, you won’t be able to polish a large surface with bench grinders, In this case, an angle grinder will do better than a bench grinder. Add a brush wheel or wire wheel with it and control it. The rest is the headache of the tool. You will get a large polished surface.
As like as polishing, removing paint from a small surface may be possible for a bench grinder, but angle grinder is the best choice for large surfaces. We generally use an angle grinder for this purpose. Here we can see that each of these two is supported by various types of work in the angle grinder vs bench grinder discussion.
Number of wheels: Bench grinders come with two wheels. That means there is a scope of setting up and using two wheels at a time in a bench grinder. Which is good for workshops as there always remains a rush of work. Using two wheels at a time doesn’t let them waste their time. Not only in workshops, is the benefit of two wheels seen in home too. You can work with your friend together at same time. This will bring some fun. You can change the wheels if you want.
On the other hand, angle grinder gives you the scope to use only one wheel at a time. So there is no chance of sharing. As there is no sharing, there is an advantage. You can use the tool from any position you want. If you want, you can change the wheel any time.
Wheel Speed: Wheel speed is a good point in angle grinder vs bench grinder discussion. In my opinion, wheel speed differs because of the wheels. The wheel speed of bench grinder is much less than the wheel speed of angle grinder. The reason is, the wheels of bench grinders are wider than the wheels of angle grinder.
Depending on wheel speed, bench grinders are generally of two types- slow speed bench grinder and high-speed bench grinder. Slow speed bench grinders generally come with the speed of around 1700-1900 RPM. High-speed bench grinders come up with the speed of around 3000-3500 RPM.
Comparing to bench grinders, the wheel speed of angle grinders are super fast. The reason is the thin wheel. AN angle grinder can provide a wheel speed of 8000 to 12000 RPM. For précised work, some of the angle grinders come with a speed of around 6000 RPM.
Strength: The strength or accuracy of an angle grinder and a bench grinder can’t be compared properly because these two are mainly for different types of works. Angle grinders come with a tiny but speedy wheel which is mainly accurate for cutting. Bench grinders come with a relatively slow but speedy wheel that is perfect for sharpening, shaping etc.
So, you can see that the core strength of these two grinders is in different fields. For cutting, angle grinder centers its strength and creates a pressure on the workpiece. On the other hand, with the help of wide wheels, bench grinder spreads its strength for précised polishing or other work performance. So, it doesn’t establish a strong point in angle grinder vs bench grinder debate.
Now you know what do you need for your tasks, right? Angle grinder or bench grinder, whatever you need, you can choose the best one for you from my top choices in angle grinders or my top picks in bench grinders.
