Die Grinder vs Angle Grinder

Die Grinder Vs Angle Grinder – What are the Technical Differences?

Grinders are different sizes and types. Also, they are versatile enough to handle small to larger projects. Moreover, grinders are well-known for delivering a precise and detailed result.

Die grinder and angle grinder, both are grinders. These two different tools are used to perform various jobs despite serving the same purpose.

So, the question is

Which tool should I choose?

Which one will deliver the best result?

Through this die grinder vs. angle grinder article, you will get the answers of all your queries.

Comparison Chart – Die Grinder Vs Angle Grinder 

If you need to handle a cutting or rough grinding project, you should pick a die grinder. On the other hand, an angle grinder is a rotary tool that will deliver precise work.

Differences Between Angle Vs. Die Grinder

From the comparison table, you have already understood that both tools are versatile. And to accomplish cutting, grinding, or polishing type work, both are best-suited.

However, we will look through the key differences between these 2 tools from below.

1. Design

An angle grinder contains a thin abrasive disc that is mounted on a rotating spindle at right-angle to the tool’s body. When you are cutting the disc periphery, you can choose the disc face to grind or polish.   

In contrast, the die grinder is a significant rotary tool; it can apply much more power to a much larger size. Die grinders can take on any attachment, and because of that, they are much more versatile than an angle driver. It can perform grinding, polishing, or cutting type work with the right attachment.

2. Size

Size is one of the key differences between air die grinder vs. angle grinder.

Although both are handheld tools, technically, you can use a die grinder using one hand only. On the other hand, both hands are required to grip an angle grinder.

Moreover, angle grinders are bulky devices and contain a handle. But a die grinder is smaller like screwdrivers.

3. Power

Speed and power are the two sectors where differences between electric die grinder vs. angle grinder are more.

Since an angle grinder is bulky and more significant, they require a larger motor to run. And a larger motor means more power. An angle grinder contains 2X more power compared to a die grinder.

If you look at the comparison chart intently, you will find that a die grinder motor power is not more than 1HP, while an angle grinders motor power is 1.5HP – 5HP. This extra power makes an angle grinder much versatile.

On the flip side, die grinders are much more powerful than Dremel devices. In the competition of power, they are incapable of producing similar power to an angle grinder.

4. RPM

In terms of RPM, here is an inverse scenario. Being a smaller tool, a die grinder is a lot faster, and its RPM range is 15,000 – 30,000. At the same time, an angle grinder’s minimum RPM is 6,500 and a maximum of 20,000.

Firstly, you will not see any noticeable differences in the speed of both tools unless you use the same attachment in them. Once you attach a similar attachment in them, the speed of a die grinder will impress you for sure. Because of the high RPM, a die grinder is compatible with diamond bits, smaller mounted point wheels, etc.

Which Tool is Best-picked for Your Project – Pneumatic Die Grinder vs. Electric Angle Grinder for Rust

  • If your project relates to grinding or cutting rough materials like tiles, rebar, mortar removing, polishing or removing rust from the large surface, pick an angle grinder.
  • A die grinder will give you the best result if you have to accomplish cutting, grinding, polishing tasks on small materials. In fact, it focuses on delivering a precise job.

Sum Up

It is significantly essential to learn your project type first, then purchasing either an angle grinder or a die grinder. Hopefully, this piece will guide you through the right kind in picking the best-suited grinder as per your project type.
