What speed should I use these tools to cut gemstones: high speed or low speed? I use Dremel 4000.

Judging from my experience with these items, I would suggest you try it at slower speeds and work up till you have acheived a speed that works best on the material you are working with. Be careful not to let the bit get to hot. Running at a very high speed seems to ruin the cutting edge of the bit. I think the speed will vary according to the hardness of the material you are working with. Do not be afraid to use a little water with the bit either. It is very important not to overheat the bit. I hope this answer is of some help to you.

We bought the dremel you bought and have the flex shaft. But you need to buy the MLCS 9400 Std. Duty Router Speed Control in order to control the speed of the dremel. This is recommended by all wood carvers and am glad we did. It is such an improvement in the use of the dremel.

I set my dremel at max speed with glass and drill bit tip under water with some grinder coolant added. This is go keep the drill bit cool. The water also helps to reduce vibration. Remember go slow let the weight of the unit do the work. I have found with my drill press set up I am able to back the drill bit off and let it cool a second or two also. You will also some glass will seem to be harder than others and will require even slower drilling, red comes to mind. Just take your time.

I have no experience with working with rocks or garden stones, so my answer is based on what I know about the Dremel Stylus. This tool is certainly very amendable to a variety of craft projects, and I use it for polishing Premo or Sculpley clay. I have found during long bouts of sanding, smoothing and polishing, the Stylus overheats, and shuts off automatically to prevent the motor from burning out. So, if that's happening in my small scale usage, I think it will happen even more often for you and leave you feeling frustrated. If the return policy on the purchase allows you to return within 30 - 90 days and you're willing to give it a whirl, then buy it. It is very lightweight, affordable and versatile. I love mine and love finding new uses for it every day. I hope my response helps you. P.S. Contact Dremel's Customer Service and see what they have to say! Good luck to you!

I only use the wheels to cut very thin metal cans at the top speed of my Dremel tool. It works very well for me. I do notice that some wheels last longer than others even though I cut the same thickness material at the same speed.Wally

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.

I would say yes. I purchased for cutting stone/lapidary work. The only concern I would evaluate is the height of the blade. Will the height of the blade guide allow you to do what you wish. In addition to harder rocks I have also cut glass tile. So like I mentioned, cutting power probably not an issue, height of blade maybe.

Yes. You xan use either an abrasive blade (cheap) or a diamond tip metal-cutting blade (very expensive). Either way you will need to go slow but the saw has plenty of power for the job.

I don't know the difference. If you are wanting cutting tools, stay away fromantic dremel. The sanding discs and other attachments wear out too quickly and are way to expensive.

I think it is 800? If you check, I think the sapphire sold as an add-on is 1,100. Personally, I think the blades look great with the ceramic. Just buy a cheap rubber eraser, the old school "toxic" type, to clean the stone.

The roatary tool (I call it a dremel) is way more versatile in terms of the materials it can cut through and how small its cuts can be. The jig will be better for longer cuts that need to be straight, but primarily in wood and you have to drill a hole to start with. If your tiles are in the wall, or made of anything other than wood or some similar hardness material, I would get the rotary tool. If you have them off the wall, a jig would serve you just as well.

If you have a lot of area to cut it is a lot faster. If you are not used to cutting curves this takes the work out of it. If you use the stencil cutter it works best if you have a temperature controller like you would use with a solder iron. If you let the cutter get too hot you can have lots of plastic strings. Medium temperature, medium speed and you will be very pleased.

not sure what the diamond blade is for , but you would be better off using a saw-zal for cutting thick metal, i would worry about ruining the saw motor by overloading it cutting thick metal.i would assume the diamond blade is for tile or maybe thin metal.

Not sure about that, but I cut quite a lot of aluminum with my radial arm saw running at the standard speed for that saw. I'm thinking it runs at 3600 rpm.

Dremel does not indicate this tool is ideal for drilling. Its two-speed setting allow you to use the low-speed setting for cleaning applications and using brush accessories, then switch over to the high speed setting for routing, cutting and sanding applications.

I agree with high speed good blade for clean cut. I like thin kerf marathon blade. It's a question with many variables...I'm a cabinet maker/finish carpenter. Maybe a little more torque for heavy beam cuts could be nice. But my Skil saw keeps me happy everywhere I go...

Hi from New Zealand and the question should really be , not what can I do with them but do I really need them for the type of Dremel work I am already doing. I'm a typical Gemini and have loads of fun trying many many craft styles. Best use for these is for glass and bone carving/polishing etc. They would probably be useful for smoothing out any chips in your bakelite projects. I recently drilled some 5mm diam holes in laminated glass and with the odd squirt of water to cool burr and flush away the ground glass they did a mighty good job with little sign of wear even after some 20 holes. My main use is for detailing seaglass trinkets. Good luck in retirement. Barry p.s. I'm not an expert!!!
