Depending on the kind of projects you take either as a DIYer or as a professional, you might find yourself in need of a Dremel or a die grinder tool.
You can use these power tools in projects that involve sanding, sharpening, carving, cutting, polishing, and grinding. In terms of features and appearance, both are comparable. But both have significant differences also.
If you are not familiar with these tools, don’t stress as I imagine you are not alone in that regard.
At some point, I found it hard to find an answer as to what the differences are between a Dremel and a die grinder are as well.
Here, I’m going into detail of what separates the two tools.
The main differences between a Dremel and a die grinder
1 – Size
One main reason why people choose the Dremel is that it comes in a small compact size, making it one of the most agile and portable power tools available on the market.
On the other hand, die grinders are the opposite since they are physically larger. They are a bit bulkier and quite heavier to carry.
2 – Power
Die grinders can either be air\ pneumatic, or electric powered. The standard Dremel tool is electric powered, even though cordless versions or models are on the market too.
Electric die grinders require more power to run, and you need an air compressor\ air supply for the pneumatic versions.
3 – Rotational speed
In terms of rpm (rotations per minute) of the attachments and bits, variable cordless and corded speed Dremel tools can max on average at about 35, 000 rpm.
On the other hand, most die grinder models top out at approximately 20, 000 to 25, 000 rpm.
The smaller the bit or discs, the less distance it has to rotate in diameter, and so the additional speed.
4 – Resilience
There’re things you would not know about a Dremel and a die grinder until you used them together.
For instance, you would only know that the Dremel is prone to overheating after a lot of continuous use.
Heating up is attributed to their utilisation of an electric power use, and their overall small compact size. Versions that use a battery pack are more prone to heating up as well.
By comparison, the standard die grinders aren’t nearly as prone to overheating. That is because most die grinder versions are all air-powered.
This means that die grinders can be used for longer periods without much trouble.
5 – One is a brand
The Dremel isn’t technically a tool, it is a brand. A die grinder on the other hand, is a type of a tool.
Dremel vs. die grinder – Which is better?
Each of die grinder and Dremel has some pros over the other.
For instance, if your job calls for larger-scale machining jobs, grinding, and sanding, then a die grinder will best serve your needs.
On the other hand, detailed engraving, sharpening, grinding, or routing will best be served by a Dremel.
