Die Grinders vs Angle Grinders

Die Grinders vs Angle Grinders

In the metalworking sector, grinders are the most important tool. Grinders can assist in completing tasks quickly and effectively. A must-have tool for every metalworking expert. They can be used for a variety of purposes, and there are several distinct types available.

Die grinders and angle grinders are the two most regularly used grinders. They have a lot of resemblances, but they also have some differences. To help you understand the differences between Die and Angle grinders, we've written this article. Let’s start with the basics.

What Is A Die Grinder?

Die grinders, also known as rotary tools, are handheld power tools that are used for grinding, sanding, or removing material from workpieces, as well as cutting and shaping, and polishing. Wood, metals, steel, and other materials work well with die grinders.

Die grinders are compact, portable power tools with a revolving spindle and a collet that contains a cutting bit. This tool has a grinding bit in the front that revolves at incredibly high speeds. Die grinders are extremely versatile as they can be used with a variety of attachments. Die grinders are generally smaller than angle grinders and are best suited for smaller workpieces.

What Is An Angle Grinder?

Angle grinders, also known as side grinders or disc grinders, are handheld power tools majorly used for grinding, sanding, polishing, and cutting. Angle grinders have a rotating disc in the front that spins horizontally. These rotating discs are called attachments.

Angle grinders come with a variety of flap disc attachments, each designed for a particular job. Angle grinders are larger than die grinders and are best used on large workpieces.

Die Grinder Vs Angle Grinder: The Differences

After discussing both grinders, we can tell that they are nearly identical. However, there are a few distinctions between the two tools that one should be aware of.


One of the differences is the size and weight of both these tools. The size and weight of an angle grinder are more than that of a die grinder. Die grinders are smaller and lighter. Die grinders are typically 5 to 10 inches in length and weigh between 10 and 11 pounds. An angle grinder, on the other hand, is much larger, with a length ranging from 12 to 18 inches and a weight ranging from 12 to 20 pounds, depending on the model.

The working of tools can be influenced by their size and weight. Because die grinders are small and compact, they are considerably easier to use.


The second most significant difference is the design of both these tools. The head of a die grinder is typically parallel to the tool's body. This design allows you to reach tight locations that would otherwise be inaccessible. Because there is no side handle, you must operate by grabbing the body with both hands. There's also no safeguard.

On the other hand, the angle grinder head is angled to the right. It has a side handle on top, which makes it more convenient and safe to use. A safety guard protects the disc/wheel from sparks, dust, and other hazards.


Another significant difference between these tools is their usability. Die grinders are smaller and lighter than angle grinders, and they have a user-friendly design. It is simple to operate with just one hand.

Angle grinders, on the other hand, are larger and more powerful. It can be utilized by holding it in two hands, making it easier to operate.


As angle grinders are bigger than die grinders, it holds a much bigger motor, which makes an angle grinder more powerful than die grinders. Die grinders have motors that are less than 1 horsepower, whereas angle grinder motors range from 1.5 to 5 horsepower.


Another significant distinction between angle grinders and die grinders is the speed at which their attachments run. It's worth noting that, despite their larger size and greater power, angle grinders spin slower than die grinders. A die grinder may spin at speeds ranging from 20,000 to 30,000 RPM, whereas an angle grinder's maximum speed is normally about 11,000 or 12,000 RPM.

Die grinders are great for precision work due to their speed and size.


Although die grinders and angle grinders perform nearly identical tasks. A die grinder, on the other hand, is incapable of cutting. On the other hand, angle grinders can cut through heavy metals, pipelines, and even polymers.


Die grinders are ideal for internal designs since they have a compact, curved circular head. Curved edges and corners, as well as polishing and grinding holes, are all included. Angle grinders, on the other hand, have a big and flat disc attachment, making them excellent for flat and large curved surfaces.


Another significant distinction is the way the tools are powered. Electricity is usually often used to power angle grinders. Die grinders, on the other hand, are mostly powered by compressed air. Many die grinders run on batteries, however, only corded electric die grinders are widely used.

In the end, both die grinders and angle grinders offer specific benefits and applications for which they are excellent. Consider the tasks you expect to undertake with either of these power tools before purchasing them, and then proceed from there.
