Angle Grinder vs Die Grinder

If you are looking for a grinder, then there are different choices available in the market. Angle grinder and Die grinder are popular choices but they are not similar. Even though they share the same last name, they are different tools and are made for different purposes.

You should choose either one based on your work. If you do not know the differences between these two or are still confused about them, then you have come to the right place. In this post, I will give you the differences between these tools so you can make a better decision on your purchase. But in short, a die grinder is made for doing versatile work and an angle grinder is made for performing heavy-duty work.

Angle Grinder

An angle grinder tool consists of a motor, spinning head, and a disc mounted at an angle. The disc can be replaced by different accessories such as brush wheel, grinding disc, and many depending upon the job that you are performing. They come in different shapes and are commonly used in heavy-duty work. Some of the applications of angle grinders are cutting, grinding, polishing, sanding, and sharpening.

Die Grinder

A die grinder is a powerful tool that is mostly used for machining the shape of dies in manufacturing industries, hence the name. They have a spinning head located at one of the ends to machine the dies. Some die grinders also have some models mounted at the right angle to use them easily in narrow spaces.

Some grinders also have flexible shafts to be used comfortably. Apart from Machining, the die grinder can also be used to perform cutting, grinding, sanding, and honing.

Key Differences between Angle and Die Grinder

Design

They differ majorly when it comes to design. The angle grinder has a right-angle-mounted spinning head with a side handle to hold it. This makes it easy for you to hold and operate. The disc or the wheel mounted on the head is protected by the safety guard.

In stark contrast, a die grinder’s head is positioned parallel with the handle. The top of the head has the required tool to do the machining of the die. Some die grinders also have a right-angled mounted head to access the tight spot. Unlike the angle grinder, a die grinder does not have a safety head.

Size

Angle grinder comes in various sizes so they have different sizes and weights. They come in as small as 41/2 inch blade model to 7-inch blade model. Small ones usually weigh between 4-5 pounds and come in 10-15 inches in length while the large ones come in 15 pounds with 25 inches in length.

Compared to an angle grinder, die grinders usually are lighter in weight. They come in 3-4 pounds in weight. Some air models of angle grinder weigh only one pound with seven inches in length.

Power

A small-angle grinder comes with a 5 amp motor that is capable of providing up to 10,000 RPM while a bigger angle grinder provides more RPM with a much powerful motor. A bigger angle grinder is useful in working on heavier surfaces while a smaller angle grinder is for small tasks.

A die grinder has generally a less powerful motor than an angle grinder and they come with less than 1HP motor. With a less powerful motor, they can have higher RPM in the range of 20 to 30k. A die grinder cannot be used to work on heavier surfaces like the angle grinder. But they are perfect for precise, and lightweight kinds of activities.

Attachments

An angle grinder comes with a definite set of attachments such as discs, stones, pads, and wheels as they are used for a definite set of works like polishing, grinding, cutting, and brushing. You cannot expect many attachments with an angle grinder.

Unlike an angle grinder, there are a wide variety of attachments available for a die grinder. It has attachments for every possible operation that you can think of. It seriously is a versatile tool. Some of the attachments that work with a die grinder are cut-off wheels, drums, flap wheels, drill bits, endmills, burrs, and more. With these tools, you can do different activities like precision cutting, polishing, sanding, drilling, machining, grinding, and more.

Finally,

With the key differences mentioned, you must have a good idea about what to choose for your specific activities. If your job requires a lot of heavy-cutting, grinding, or polishing hard surfaces, then a big angle-grinder should be your first choice. If your work has a wide variety of activities on different surfaces with high precision, you need to have versatile tools. For this type, a die grinder is a right choice. I hope this article with a brief review and detailed differences helps you in choosing the right tool for your specific activities.
