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. Once this bit is attached the dremel could spin its way through almost any small rock that needs to be cut.
Before you go hacking at your lovely rock or stone though you want to have a read of this. 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. When you have got all of this kit, you are ready to rumble. Now, time to get down to the nitty gritty ha, get it? Because grit is stone and we are talking about cutting stone? 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.
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. 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. 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 is also handy to have a stack of diamond bits at hand because you will easily go through a few during the cutting process.
There is a certain technique which works best when cutting using a dremel rather than going straight in on it. You want to move slowly and let the diamond bit do the hard work rather than pushing into it manually. Just take a break and wait for it to cool down again before continuing to cut. This too requires some important knowledge.
Luckily, we have got you covered! Have a read on. Cutting gemstones is much the same process as a rock like above, but there are a couple of super important additional steps that you certainly need to undertake to make sure that you are doing a good job of the cutting. When cutting your gemstone, extra work does need to go into the process. This starts from the very beginning with your preparation and research stage. When cutting gemstones for jewelry you want to identify which gemstone you are going to be working with and if there are any inclusions in the piece of stone you have.
On top of this preparatory work, when you are cutting a gemstone, you also need to preform the stone before you commence the cutting of a precise area.
Using a grit diamond bit, you want to roughly gauge a shape in which the gemstone is going to be cut into, taking into account inclusions and the crown facets. During the preform you will want to remove the inclusions first, and continually wet the gemstone to make sure the stone remains cool. Depending on how serious or technical you are about this project will affect this next step. For some early beginners or those not completely into this process, you could effectively start cutting after the preforming has finished.
But there is another step which can be taken before cutting to ensure a precise and accurate cut. This is the heating of a dop stick and wax, which essentially provides a handle on the gemstone to allow more precise and accurate cutting. For this step you merely need drop sticks, a hot wax and a heated gemstone to allow adhesion between the stick and the stone.
Much like when cutting other rocks and stones, you want to use a diamond bit — whether that be a tip or a wheel on your dremel to perform the cutting of a gemstone.
The diamond means you get a clean and precise cut on your gemstone and minimise the chance of cracking or rugged edges to your stone. If you have finished cutting your rock into a much more manageable piece of material which can be easily worked on now, you will be looking at trying to shape or carve it into whatever your desired project goal is.
These things are amazing. In terms of shaping the rock, you are going to want to use much the same technique as we went through for your cutting process. Instead of drawing on your lines to cut along like you did previously, for carving you are going to want to create a rough outline of the design you had in mind by firstly drawing it on and then going over the drawing with a light engraving stroke from the dremel.
This will mean you can follow the design throughout and have no risk of it rubbing off. A T-square braced on the edge will help mark 90 degree lines more accurately.
This line is where the cut will occur. There are some different Dremel attachments you can use to cut acrylic. Choose based on what you already have, or your specific use case. The Multipurpose Cutting Bit can do the job on its own, but you will need a very steady hand.
Attach this bit directly into the Dremel. Dremel makes the Multi-Purpose Cutting Kit, which includes a few cutting bits including the and a mount that keeps the Dremel straight up, making sure the cuts are not beveled. When making multiple cuts, we recommend this kit.
Instead of handling the Dremel straight up with the cutting bit, you use cut-off wheels with a sideways action. For very thin acrylic or quick cuts that do not go a long distance, this may be the best choice. You will also need a mandrel to connect it to the Dremel. If using the , set the Dremel speed to 6 or 8. Any lower may not cut through the acrylic, and any higher will melt the material more than cut it.
Check your mounting and reset if necessary to make sure the line that you need to cut is off the edge of the workbench. The scrap piece you are cutting off should be over the edge, since a fall when it is cut off might damage the acrylic.
Begin cutting along the line you made when preparing the acrylic sheet. Make sure the cutting attachment is cutting straight up and down, and not at an angle.
Follow the line in front of the tool instead of concentrating on the cutting edge itself, this will help to stay in a straight line. Use a smooth and slow action, since pushing harder in different spots may make the cut uneven. Have a spray bottle or non-breakable cup handy, and wet the acrylic and cutting bit on a regular basis. It may be easier to have someone else do this for you as you are cutting.
This will cool down the bit and help prevent burns and melted spots. Celtic Dreams. With silicon carbide abrasive throughout, these polishers are for smoothing, removal of oxides and a high lustre polish on all of the above materials. Hard, yet flexible, and no additional paste required. Use the Soft Wheel Green see below product for a final mirror shine after using the dark blue first and then the light blue Chrom PLus polishers.

There are three grades and it's best to use all three consecutively, working your way through from Green which is medium grit, then the fine Orange and finishing with the Pink, extra fine.
Using them in this way will result in different textures as you move through each polisher, so if you like the lustre that the green has left, stop there.
Otherwise move on to the orange and pink to leave you with a really nice sheen on your work. They are made of cotton and impregnated with the abrasive, aluminium oxide.

Use them dry. The discs are designed for use in a pendant drill or rotary tool, such as a Dremel. Simply stack 2 of the same grit discs on a screw mandrel making sure to face them the correct way. I recommend a selection of three grits, a rough one for removing oxides Blue or Dark Grey , a medium grit for further removal of light oxides and pre-polishing Brown , and then a finer one for semi-finishing and blending Green and Beige.
They will polish the settings without any damage to the stone. For a pre-polish to polish, work your way through the grades, beginning with the coarsest 80 , , , and finally grit being the finest.

Helpful note: Regularly clean and dress your diamond impregnated polishers using a Diamond Dressing Tool. This will expose a new layer of diamond grit to the surface of your polisher producing a sharper edge and removing any dirt and contaminants.
Take a closer look at the Diapol Diamond Polishers here. The true advantage of the Airflex polishers is that they are heat-free, or cool-running. The buffing wheel have tiny air pockets interspersed throughout the polisher meaning they produce no heat and will stay cool, which in turn means they polish and grind quicker but produce no heat. Take a closer look at the Airflex Polishing Wheels here. These rubber polishers help to smooth out the roughness on metals particularly on platinum, gold and Argentium silver.
