How DO you engrave rocks?

With a power tool, of course!

To engrave rocks in this way, you’ll need access to a multi-purpose rotary tool (I own a Dremel), but after that, the process is surprisingly easy. It’s so easy that my kids can do it, and their stuff looks legitimately great. See that dragon up there on the left? Isn’t it freaking awesome?

Yeah, my eleven-year-old daughter made that.

Of course, if you’re not into dragons, you can also engrave inspirational words and hearts and mandalas and such, but we’re pretty into dragons.

You can also engrave rocks of any size, and the diamond bits that you’ll be using come in a variety of sizes, as well. We’ve been engraving larger rocks like the ones in these photos as a way to decorate a garden border, but you can also engrave small stones, and they’d make great party favors or holiday gifts.

How to Engrave Rocks with a Dremel

Want to give it a try? Here’s what you’ll need:

DremelThe model that I own is several years old, and I’ve done some VERY weird things with it.

diamond bitsI have a variety of widths, and I use them a lot. My latest obsession is engraving on these dirty old glass bottles that I scrounge from a 50-year-old dump site in the woods behind my house, but I’ll tell you all about that some other time!

Sharpie. You can use a pencil if you’re making very thin lines, but a regular Sharpie is fine for my purposes, and perfect for the kids.

rocks. We live in limestone country here in Indiana, and so that’s what we mostly use, that and shale from the creek beds. These diamond bits should cut any stone that you want to work with, however, so feel free to go nuts!

water. Get a pitcher, fill it with water, and put it next to your workstation. Oh–and do this outside. You don’t live in a mine, and so you don’t want to breathe rock dust where you live.

vise. If your rock is smaller, you’ll want to clamp it down. We don’t need to with the heavy stones that we usually use, but here’s what it looks like in my portable bench vise:

How do you engrave rocks? With power tools! And even your big kids can do it.

1. Draw your pattern. Draw anything that you fancy, but keep in mind the width of your lines. If you’re going for something thin and detailed, switch to a pencil instead of a Sharpie like I use.

2. Clamp your rock down, if needed.

3. Get the rock wet. You want to keep the rock wet, both because it lowers the temperature of that spot where a LOT of friction is going on, and because it gets the rock dust out of the way so that you can see what you’re doing. Pour a little water from your pitcher onto the rock, and continue to do so every time you pause your work.

4. Begin to trace your lines. Hold the Dremel perpendicular to your rock (you won’t get a nice cut if you angle it like you do a pencil), and begin to lightly go over your Sharpie lines. You’ll want to go over the same line several times, and then probably again in the process of creating your finished piece, to smooth out any unevenness.

You’ll find that you can make your lines any depth that you want. In the top photo, for instance, the stick figure family is fairly shallow, but the dragon is almost the depth of the drill bit in parts, and they both look great. If you’re carving into soft rock such as limestone, and if you want your piece to live outside, you’ll want your engraving to be rather deep, since limestone weathers easily.

When your engraving is finished, give the rock another good rinse to clean off the rest of the rock dust.

These rocks make great garden decorations (think plant markers or house numbers) and great gifts, especially if they’re made by a kid.

I mean, don’t YOU want a dragon carved onto a rock for Christmas? I know I’ve already put in MY order!

  1. If generating rock dust, a P100 half-mask respirator ($15) is STONGLY suggested – look up silicosis some time…

  2. Thank you Scott for this comment. And thanks Julie for the post. I just got a Dremel tool and I´m thinking of carving wood and stones. I have gloves, eye protection and also an unopened 3M 6211 paint project respirator which is great for protecting your lungs.

  3. I am trying to Branch out on my own on my work I do need to work on granite usually spray paint and then detailing buy pain but it’s time consuming I’m wondering how and which tool would I be able to use to like basically engrave Into the Stone and what the price of the tool? I can show u some what work that we have done but I would like to try and branch out more any idea

  4. And before engraving your glass make sure it isnt a valuable bottle. Those old bottles are collectables.

  5. Hi there! I currently have the dremel stylo + tool. I use the ‘river’ stones from my local dollar store. Is the stylo+ tool strong enough to carve into these (or other) stones? And should it be at a higher rpm or lower?
    Any input is greatly appreciated.

    1. Keep in mind that I don’t have that exact Dremel, but I do think it should work. The two most important factors are 1) a diamond bit and 2) keeping the rock wet, and you should be able to achieve both of those with any type of Dremel. I actually don’t know about rpms, but off the top of my head I want to say that a higher rpm would be better because then the rotary bit would just be working that much harder? In my opinion, I feel like you should go into Scientist Mode and do some experiments, and then get back to us with the results!
