Pencil grinders are a great tool to have for working with materials such as metal, wood, and more. They can sand down any serrated edges and polish them down smoothly. As a small tool, it helps when you need to fine-tune some aspects of your project.

Here’s what we recommend.

A Few Things to Consider Before Buying a Pencil Grinder

You should first consider the speed of your pencil grinder. Faster speeds translate to a more powerful tool. You should also consider the weight of the tool. Lightweight pencil grinders give you more control. Lastly, pencil grinders that come with different shaped bits can be used in different applications, and add to your tool’s overall versatility.
