Will any of these burrs cut through thin rocks (jewelry)

Depends on the rock! Mica chews the blades up really badly, and other shiny or hard stones are really bad for them. Sandstone, granite, and anything with a 'soft gritty' feel to it seems to work out really well. I've made 20+ pendants with these, including both putting single holes (which are a little large! Warning!), doing lines (also a little thicker than I'd like!) and carving them into shapes. Think about 2mm wide holes. I actually love the crap out of these for cutting stone, and work with them a ton. They also work great on bone. If doing glass like the other feller suggests, go very slow, with water, and don't let it heat up or you'll break the glass. You also need to use one of the flat-ended column types at an angle to really carve into it quickly, or the rounded cylinder shape to just press on through. The points will not work for this and are better left to detail work going sideways. There's also different bits in the newer version, including a bit with a fat head, tipped by a thin little "blade round" which is fantastic for straight lines and engraving if you can handle the width.

Not sure about minerals, but it cuts and grinds aluminum well, but that is a lot softer than rock. I will be trying them on stainless steel tubing in a day or so, but still, rocks are probably harder.

As with the last answer, I have not used this product specifically, but something very similar. They are designed for cutting glass, and stones. But high speed and water are necessary.

They are big for jewelry!! And cheap quality for lasting to cut more than a rock with the same but. They are like the burs that they use for big straight hand pieces the pedicurists to remove hard skin from the sole. I bought them for dental technician work and they are inappropriate. Pay attention on the width of their shank to fit your hand piece.

To start, i am not the best person to answer this question. but i will answer as my limited knowledge allows. from what ive done it is POSSIBLE to cut through glass, however very difficult. i did manage to make a hole in my glass beer bottle that i was testing this product on, but it took quite a bit of effort and time. i am not sure if rocks would be easier or harder (i seem to think it would be more difficult and want to say no, but i have not tried on rocks) i hope this answer gets your through until a better more experienced reviewer can answer more exact and knowledgeably.

It could cut through them. I guess you would want to use a "wood" blade. How thick they are and how much effort it has to take to cut them will determine how long you can run it. I use it for PVC pipes to give you a reference point (if that helps)

Yes. You will need a guide to cut a straight line. Take your time. The saw will cut single pass. But to avoid chipping the edge from overheating the stone, I would recommend making a couple passes. Cut the stone outside on saw horses. It will make a mess. Use water. Will only take a few minutes to make this cut. Good Luck!

My wife drills small stones and sea glass with a Dremel bit #7144. Any drill bit with a diamond tip end should do it. Depending on how think the rock is, the drill bits won't last too long.

Yes they will. I make spoon jewlry and for that they work. Any thicker I don't know about though.

Beth,The carbide and or diamond particle bits should be able to. Try them out on a piece of scrap material first. Be sure your material is held down so it won't move. Try a gentle touch first.You may want to "GOOGLE" DREMEL bits for cutting stone and hard wood...there maybe more robust bits for that purpose.What do you make?I hope this helps.Tom Lewis 602 214 4617

Never tried but if your spade bit is sharp and take your time with plunging I'm sure it will.I recently had to drill 3/8" plugs in oak with a very dull plug cutter, took my time plunging, got the job done.

That depends on what you are cutting. So far, I have cut 100 pavers and 300 brick down the length of the brick. There is no noticeable wear as of yet. If you are cutting thick pieces of granite that are not going to need to be perfect on the face, then it should work. If you are cutting tile, where chips will be a problem, then no, it wouldn't be good. A smooth rim blade would be better for that.

Yes, but probably not on all of them. I put a wicked edge on my Gerber Parang and also on one of my smaller inexpensive hatchets... but if it is too large or thick, probably not a good idea. But Hey.... what do I know? I use a stone on my axe and large hatchet, but I'll bet it would work.** please see my comment **I wouldn't use anything particularly large or heavy if you want this tool to last. No replacement elements available from Smiths.

Small rocks yes but anything over an inch in diameter would be too much. These tools are for small jobs and do them well. Rocks are another issue entirely. Get a rock tumbler or 6" polishing wheel.

Yes , if you don't let them get in too bad of shape . If you do it regulary so they are not real dull ,it is easy . The hardest thing is keeping the correct angle but that problem is eliminated with the dremel tool because it has a guide to make sure the angle is correct . If your blades are damaged from rocks or extremely dull this tool will not do a good job simply because the grinding wheels don't last very long . When that happens I use a bench grinder first and finish dressing the wheel with the dremel .

Yes!!, but be careful not to hit rocks or anything that is too big for the teeth or it will nick them and then need to be filed and sharpened.

If you mean chisels this would work great. If they have a rounded edge I am not sure what you would use.

Yes. Small or large sized blades, the two grits on this stone can take literally any straight edged blade you choose to sharpen. Use the fine grit to hone the edge slightly or put the finishing touches on the blade. Use the courser grit to repair nicks and prepare the edge for the finer grit polishing stage. I have used it for my Swiss Army 2" packet knife and the stone does the job.

Yes, it will, but first, you need to slice them, about a quarter of an inch thick.

Just had a wee play on a couple of beach pebbles which were pretty hard and not a problem. Keep speed down a little and keep dipping rock into water to keep tool cool as I believe over heating burrs can lead to loss of bond between diamond and burr. Rips into glass and shell with no problem. Note I used the larger diameter burr that was already in tool. Good luck from New Zealand

I hvnt needed new stones , i read reviews that say you can but i hvnt personally tried it the stones i got make my knives cut paper easy, not shaving sharp but good enough for me i also used a standard wet rock hope my input helps
