Differences You Should Know About Die Grinder Vs Angle Grinder

If you compare the die grinder to an angle grinder, you will agree that there are many similarities and differences between these two power tools.

We have noticed that many professional use die grinder for smaller and lighter grinding work. They are well-known for their accuracy during grinding work.

On the other hand, due to their high performance, angle grinders are best suited for large and heavy tasks and situations where precision and accuracy do not come first.

So, which one should I talk to? The best? Personal preferences and the nature of the task you are doing will be of great importance. Most grinders are pneumatically driven.

Well, let’s take a good look at die grinders versus angle grinders and determine which tool is best for you.

Understanding What Is A Die Grinding Machine


These are universal one-handed tools. Their heads are often perpendicular to the driveshaft and sometimes even parallel. They have limited productivity and are mainly used for polishing, grinding, sanding, and cutting smaller and lighter metals.

What is Angle Grinder?


An angle grinder is nothing but a Powerful tool that particularly used for grinding and cutting large and heavy metals. They are limited by their strength and the range of accessories that can be attached to them. They are bigger and heavier than grinders, so the user has to use both hands to hold them in place.

Angle Grinders Vs Die Grinders: The Main Difference

NUMBER 1. Large and heavy angle grinders

The dimensions of the angle grinders are both large and heavy. The average size of the grinding head is 5 inches and 11 pounds, while the angle grinder is 12 inches at 6 + pounds.

NUMBER 2. Power Source

Although you can run a die grinder machine with electricity but electricity as the only power source to run is not common with the pneumatic die grinder. This type of die grinder can work if you connect it with air compressors although the air compressor can’t be run without electricity. Different types of grinders may require different amounts of air pressure (which is measured in CFM) to operate.

Angle grinders, on the other hand, are mainly powered by electricity. you have to collect it with your power outlet to run it in a full swing.

NUMBER 3. Die Grinders Run Faster Than Angle Grinder

Since grinders have smaller discs and holders, the distance to the rotating disc or holders is relatively smaller. This increased the speed of the grinders.

Intermediate grinders run twice as fast as angle grinders. It can run at an average speed of 21,000 rpm, while angle grinders reach an average of 11,000 rpm.

NUMBER 4. Grinding and Cutting – Main Purpose of the Angle Grinder

The grinding wheels of an angle grinder always determine its function. There are two main types of grinding wheels: the grinding wheel and the cut-off wheel. There are also folding bikes, but they are not common.

Other types of discs or accessories can be used on an angle grinder, but they are often simple.

Number 5. Angle grinders, more powerful than Die Grinder

Angle grinders are more powerful in the field than die grinders. Most angle grinders have a power output of about 1.8 HP, while a punching machine can have up to 0.25 HP.

NUMBER 6. The angle grinder is better suited for heavier, larger, less accurate and more powerful jobs

Angle grinders are not only very powerful, but also have large and heavy cutting and grinding wheels. Angle grinders are therefore ideal for cutting metals such as large pipes and steel beams.

You can achieve a relatively straight cut, but not as accurate as with a smaller, thinner cut-off wheel for the grinder.

NUMBER 7. Plate sizes are highly variable

The dimensions of the angle grinders are larger than those of these machines.

  • 4½ Inch – 115 mm (most common)
  • 9 Inch – 230 mm
  • 7 Inch – 180 mm
  • 6 Inch – 150 mm
  • 5 Inch – 125 mm
  • Grinding discs for grinders range from 2 to 3 inches.

What are the similarities between angle grinder and die grinder

There are few similarities between the two types of tools that you can easily identify.

NUMBER 1. Turning tool

In the first place, punching machines and angle grinders are rotating tools. The tools can rotate wheels, drills and chisels, thus exerting a force on the material to be processed.

NUMBER 2. Both can use different wheels or attachments on the tool head

Both the angle grinder and the grinder have the possibility to switch between different nozzles or grinding discs on their heads. Both tools can be detached for different tasks and attached to a wide range of accessories.

What’s better? – Angle grinder v/s Die grinder

The choice of these two instruments will largely depend on the type of work carried out. It all depends on your request. Before choosing an angle grinder or stamping machine, several factors have to be considered.

For example, you have to ask yourself if you have a dice mill;

  • You need a lighter tool.
  • If your task requires a high degree of precision, use the grinding machine’s die for precise cutting, for example when carrying the engine in and around the car.
  • If you don’t mind, most grinders.

Or you might consider an angle grinder, if. . . ;

  • Their main task is to cut and grind and then choose the most suitable angle grinder.
  • If you want a powerful instrument.
  • When you need a tool for large, heavy jobs such as cutting thick metal, steel beams and piles.

Wrap it up, now you know. Depending on the task and personal preference, you can choose between a stamping machine and an angle grinder.

However, tool protection must not be forgotten. It’s very important. These two tools produce a lot of debris in the air that can be very dangerous for the eyes. Observe the safety instructions when using tools.

When purchasing one of these tools, bring safety goggles and a pair of gloves, as your hands are at risk due to the proximity of your head. Take care of yourself. Have fun with it, because it’s the most important one.
