We are gonna dive into a step-by-step guide on how to cut, then shape, then polish your rocks and stones.

Whether you are a beginner or intermediate looking to cut rocks, carve stone or shape gemstones, you can find out all you need to know about this process below and also discover just how useful a Dremel can be in polishing some gemstones that you may have found yourself.

Without further ado, let’s get cutting!

Can Rocks/Stone be cut with a Dremel?

Dremels are pretty handy pieces of kit to have lying in the garage. Their versatility is immense and they can be used for almost anything – provided they are equipped with the correct attachment – from sanding to cutting wire around the house. Using a dremel, we are going to look at how to cut, shape and then polish any given rock.

I know I said dremels are good for anything but it’s important to note that the type of rock you are planning on cutting does matter. Normal, soft rock is malleable and easy to shape due to its texture. If you are looking to cut harder or larger pieces of rock/stone, you should maybe look at a tile saw or angle grinder as an alternative, purely because the dremel would take you ages and provide you with a poorly angled cut.

This is particularly true of larger rocks/stones which would just be unmanageable – it’s like using a hand saw to chop through a tree log, you’re just better off with a chainsaw. Despite this dremels are actually hugely handy at cutting and shaping rocks/stones and particularly handy at working with gemstones, because of their intricacy and accuracy and have a renowned status within arts and crafts because of their positive attributes.

If you haven’t already got a Dremel, I can highly suggest this one specially for Cutting & Polishing Rocks!

What dremel attachment bit to use for cutting rocks?

Before you start going at that rock, there are a few things you should have in place first. Importantly, a diamond bit attachment for your dremel is crucial.

Or also here is a decent set as well that Includes A LOT of other Pieces you will need.

Without this, the dremel is going to struggle and most probably stutter its way through the rocks/stones. Once this bit is attached the dremel could spin its way through almost any small rock that needs to be cut. The ‘diamond’ bit of that might send you into a frantic flush of financial worries, but do not fret, these attachments are not expensive whatsoever. Cheap and easy to find in any good hardware store or online here these bits are going to be a necessity to cut through your rock/stone and carve it in the way you want.

Now, as I mentioned previously, provided you don’t have an excessively large rock/stone that you require slicing (if you do, save yourself the hassle and get an angle grinder or tile saw) then you can easily use a dremel to slice your way through the rock to cut it into whatever shape you like. Before you go hacking at your lovely rock or stone though you want to have a read of this.

Items you will need:

To make sure you get the perfect, smooth finish everyone would desire on your rock, you need to have a few pieces of kit before you start cutting. You’re also going to need the following before you start:

–Diamond bit attachment

–Dremel

–Marker pen

–clamp or set of vices

–PPE (gloves, mask, eye mask)

When you have got all of this kit, you are ready to rumble. Now let’s find out the process of how you can cut rocks with a dremel multi-tool.

Step by step guide on how to cut rocks with a dremel

Now, time to get down to the nitty gritty (ha, get it? Because grit is stone and we are talking about cutting stone? Na? Okay… I’ll see myself out). You want to make sure that you have your correct dremel tool and diamond bit to hand and throughout this whole procedure remember to never touch the bit when the power is on on the machine, it only leads to one thing – disaster.

1 – Preparation, Preparation, Preparation

Like you should with any intricate project, you want to plan your actions first. Firstly, I would recommend that you practice using the dremel on some throwaway material first to get a feel for the tool, particularly with the diamond bit attachment. Once you are feeling confident, you want to dawn your PPE (eye mask, gloves and facemask) to protect you from any dangers that could fly off the rock or tool.

2- Line it up

Once you have got yourself prepared for the cutting, you want to plan exactly where you are going to be cutting. Without acknowledging your direction, you may face a squint or curving cut that could be undesirable or a flat-out mistake. This is where your marker comes in, to draw your appropriate line on the stone.

Once you have identified which area of the rock/stone you want to cut you will need to secure the rock in place ready for the commencing of cutting. This is best done using a clamp or vice. Despite limiting manoeuvrability during the cutting process, this is the safest and best option to use when cutting. It’s not advisable to start cutting with the rock in your hand as it can end in blood and gore.

4- Attach the diamond bit

If you haven’t already attached the diamond bit to your dremel for practice, then this is the point you need to do so. Don’t forget it or else you’re in for a seriously long and rugged cut of the stone/rock. It is also handy to have a stack of diamond bits at hand because you will easily go through a few during the cutting process.

5- Start cutting

There is a certain technique which works best when cutting using a dremel rather than going straight in on it. Setting the dremel to half speed to avoid any unwanted breakages on the bit or motor, you will want to adopt a 45 degree angle for cutting and use a sort of ’pecking’ movement. You want to move slowly and let the diamond bit do the hard work rather than pushing into it manually. Eventually you should make it through the cut and have a relatively clean, sharp trim on your rock/stone.

(p.s it is important to note here that the diamond bit may turn red because of extreme heat from the friction caused by the cutting. Just take a break and wait for it to cool down again before continuing to cut)

6- Carve, Shape or Polish

Now that you have cut the rock/stone into your desired size, you will not want to start carving, shaping or polishing. This too requires some important knowledge. Luckily, we have got you covered! Have a read on.
