Main Differences Between Die Grinder vs Angle Grinder
The main differences between die grinder vs angle grinder are:
- Die grinder is a smaller tool and requires only one hand for use, whereas an angle grinder is a larger tool that requires two hands to operate.
- Die grinder is a tool made for precision work, whereas an angle grinder is a tool made for cutting large materials
- Die grinder is usually powered with less than 1HP, whereas an angle grinder is a tool that has more power than 5HP
- Die grinder tools are usually battery or air-powered, whereas angle grinders are normally powered by electricity
Exploring Die Grinder and Angle Grinder Features
Even though die grinders and angle grinders can be quite different, they do share some similarities and features found in both power tools.
RPM
Both of these power tools rely on revolutions per minute (or RPM). This is one of the ways in which you can gauge how powerful each model is.
Die grinders have a spindle that revolves and this helps to create friction between the tool and the material you are working on. The faster the RPM the more powerful the tool is and the quicker you should get the job done.
Angle grinders have a wheel that rotates at a high RPM. This is also designed to create friction between the tool and the material. Even though angle grinders are more powerful, the basics of how each tool works is essentially the same.
Cutting
Both an angle grinder and a die grinder can be used to cut materials.
There are some differences in the power and the types of materials that you can use each tool on. However, it is a common trait in both of these power tools. Different attachments for each tool can also help to extend their functionality for example with sanding and polishing capability.
Cost
While the price of specific models of die and angler grinders will vary, the actual cost of each tool is roughly the same.
Even though this is a bit surprising at first glance – as one tool is more powerful than the other – it is because they serve different purposes. When you start to add on different parts to a die or angle grinder, you’ll find the cost begin to differ. However, at a base level, there isn’t a lot of difference in the cost of each power tool in similar quality.
Safety
A problem with both of these power tools is that they create a lot of dust and debris can come flying off the materials you are working on.
This is why when using either of these tools, proper safety equipment should be worn. This includes things such as protective glasses and also gloves to safeguard your hands.
Both of these tools can be quite dangerous if you don’t use them properly. You don’t need to be scared of either of these power tools but ensure you wear the right safety gear and follow the correct usage instructions.
Features unique to die grinders
Faster RPM
Even though both die grinders and angle grinders rely on RPM to do their job, die grinders tend to have a faster RPM.
They usually average around 20,000 RPM. This is because they are smaller power tools overall and have smaller discs. This allows them to spin faster although they generally have less horsepower. The fact that they are also used for more intricate tasks is another reason why they need to have a faster RPM overall.
Air powered
Most die grinders are air powered. While you will find some that aren’t, this is the main feature that is pretty unique to these tools especially when you compare them to an angle grinder.
The power comes from air compressors which is generally sufficient for home use and taking on home DIY projects.
Precision work
Die grinders have been designed to carry out precision work. This is why they are smaller and lighter as they need to get into tight spaces.
This work can include sanding and polishing. Depending on what bits you attach to a die grinder, they can also be used for cutting for small pieces of wood, plastic, and even some metal as well.
Features unique to Angle Grinders
Larger tool
Angle grinders are bigger power tools than die grinders.
Even though they are still a handheld tool, they are a bit larger and may sometimes require two hands to operate safely and efficiently. These tools are also a bit bulkier as well whereas a die grinder is shaped more like a screwdriver.
More HP
Angle grinders will generally have less RPM however they will come with more horsepower overall.
The average horsepower for an angle grinder is between 1.5 HP and 5 HP depending on what model you buy. This makes them very powerful and ideal for working on larger materials especially when it comes to cutting.
Electric or battery operated
Angle grinders are usually powered by the mains electric or by a powerful battery.
This helps them to achieve more power. It can be a bit limiting if you need to plug it in or the battery doesn’t last very long, but it is a small trade-off for increased power overall.
Comparing Die Grinder and Angle Grinder pricing
While you will get both expensive and inexpensive models of both these power tools, the average price isn’t massively different in general.
These two tools are designed for different purposes so they aren’t in direct competition with each other. This is why the cost of each tool can be quite similar even though they have very different features when it comes to size, power, and how they are powered.

Our Verdict: Use a Die Grinder for Smaller Work and an Angle Grinder for Larger jobs
At first glance, it is easy to see why many people think these two tools are the same. They both rely on RPM, the cost difference isn’t massive and they can both cut materials.
As you will know by now, once you start getting into the differences between these power tools you can begin to see why you may need both.
Die grinders are designed for smaller and more intricate DIY work that doesn’t require a lot of power but a high RPM. This can include cutting but usually means polishing, sanding, and getting rid of rust.
We recommend the Makita GD0601 1/4″ Die Grinder as an overall great product that has good power combined with a host of other features. It is fairly well priced as well so isn’t going to set you back a lot of money as a tool for home improvement.
Angle grinders are more suited to larger jobs that require a bit more brute force. They are especially good for cutting tough materials and over larger surfaces that a die grinder just won’t be sufficient for.
For an angle grinder, the DEWALT Angle Grinder Tool is a solid choice. Not only is it affordable but it comes with a powerful motor, Dust Ejection System and 3 type 27 guards.
