What’s The Differences Between A Die Grinder And An Angle Grinder?

There might be some confusion about two tools Abrafast offers –- the die grinder and the angle grinder.

Although they are similar, the two have distinct differences in appearance and application capabilities.

The main differences between the two grinders are their design, size, and power. An angle grinder is for cutting and rough grinding while a die grinder is a rotary tool used for precision work.

The angle grinder is larger so it should be operated with two hands. In comparison the die grinder is a relatively smaller power tool.

The angle grind relies on electricity as its power source. There are corded versions that require that the machine be plugged into an electric outlet. There are also battery versions, which are more mobile and can be used in a place where there are no electric sockets.

The die grinder relies on compressed air and a battery has its power source.

There is also a difference in the speed in which the wheel or blade spins. The angle grinder’s speed for the revolutions of the blade is 6500 to 2000 RPM. The die grinder is faster with a speed of 15000 to 30000 RPM.

There is also a difference in power due to the size of the motor that works the tool.  The angle grinder is more power due to its 1.5-horsepower motor. The die grinder features a motor that generates less than 1-horsepower.

The angle grinder is a rough grinding and cutting tool. It is commonly used to cut rebar, tiles, and masonry and to remove mortar and rust.

The die grinder is a precision machine that cuts, grinds, etches, and engraves glass, metal, and wood.

In addition, the angle grinder is designed for a larger diameter disc.

Angle grinders work best on flat surfaces because they use discs that have a flat cutting surface. They are also ideal on external curved surfaces that extend across a large area.

On the other hand, die grinders are best suited for grinding and polishing holes, sharp curves, and complex internal profiles.

Of the two, die grinders are considered to be the more versatile. There are wide assortments of attachments that are available to work with the die grinder. That is what makes it a versatile tool.

As far as price is concerned, the angle grinder is relatively expensive when compared to a die grinder. Pneumatic die grinders are very inexpensive in comparison.

So, if the job requires a powerful tool to perform a lot of rough grinding, involves cutting hard materials including rebar, tiles, mortar and rust removal or polish a large surface, then your choice should be an angle grinder.

However, if the job requires precision grinding, cutting, grinding, and polishing small surface, working small tool bits including a carbide burr, or you perform do-it-yourself projects on wood and stone, then your best choice is the die grinder.
