You can cut any thickness at all....if you have the time.

I've done 3/16" with no problems.

I use all sorts of bits for mine - just drilled a lot of holes in seashells for my daughter to make a neckless (used a diamond bit). I've used it to cut holes in tile, a lot of small plastic works and more. It's a fantastic tool as long as you have a LOT of bits.

Oh, and I clean stuff with it too - small wire brushes can clean up rusted tools.

I'd not suggest using it to sharpen anything though.

I watch wallyworld for their HUGE dremel multi-tool pack on sale its like 1 foot tall has a bunch of common tools and quick changers. Then just get what you need in the future you`ll figure it out.

The fiber cutters are nice but a bit pricey, I've cut 3/16" too, but I don't use it as my primary cutting tool.. only for hard to reach spots or when I can't use other tools because of fire hazards, vibration concerns, etc.

Martin - My dad got some sharpening adapter for his dremel and uses it to sharpen his garden tools, seems to work for him.

^^^ This.

I use mine for many small jobs, and it works very well so long as you know its limits and realize that most of the cutting wheels/stones/bits should be considered consumables.

I have the kit that is meant to sharpen lawnmower blades; stone wheel and a piece of plastic that sets the angle. I still prefer to just clamp the blade in a bench vise and freehand it. Works well with touching up axes, machetes, etc. too. Would not use on a knife blade...

High speeds and minimal load on the bit(s) are the 2 secrets to using any kind of Dremel tool.

They're not meant to replace a 4" handheld grinder or an 6" bench grinder, people who keep that in mind will usually have a lot more success using them.

I've got at least 4 of them that I can think of, couple of battery operated ones that are nice for quick and easy jobs, I've got one mounted in a little drill press/stand that Dremel still sells, great for lightweight work.

Didn't see it mentioned but if you get one be sure to use eye protection. The bits used when turning at high speed can explode with out warning. The bits most likely to explode are the non-fiber reinforced cut off wheels (zip wheels).

Favorite uses are the zip wheels to slice off bearing races. Usually takes a few wheels but it goes through the hardened metal like hot butter.

Very true.

I suggest glasses + a face shield... just like 4.5" Grinders the discs can explode and lodge themself in your face, throat, etc...
