Dremel 8100 Review (8v Cordless Rotary Tool)

The 8 volt Dremel 8100 sits behind the 12 volt Dremel 8220 in Dremel’s cordless rotary tool range.

To summarise this Dremel 8100 review, there is nothing particularly about this tool. But, it does sit awkwardly in the cordless Dremel range.

If you are thinking of getting a battery operated Dremel, we would look at the Dremel 8220 for value for money, and the long term benefit of having a newer model tool.

Alternatively, the Dremel 8050 is lighter and more user friendly, but with similar performance specs.

However, if an 8 volt lithium ion battery is fine with you, as well as some other minor limitations of this tool compared to the 8220, you can keep reading on below about the 8100 model.

Dremel 8100: Buyer’s Guide

What is the Dremel 8100?

An 8 volt, variable speed, cordless Dremel rotary tool.

It sits in between the Dremel 8220 and Dremel 8050 in terms of size and performance in the Dremel battery operated range.


What is the Dremel 8100 used for?

It will accept most Dremel accessories/bits – so, you can use it for any bit specific task.

Dremel rotary tools are a finishing tool. You would best use it for working on thinner and softer materials.

If you use it to consistently cut or grind thick metal for example – you either won’t get through the metal, or you’ll burn out the battery.

Seeing as it’s a cordless tool – it’s good for workspaces where you don’t want a cord in the way, where you are away from power supplies and where you are moving from workspace to workspace.

Who is the Dremel 8100 not for?
