   I use the two-inch angle grinder (Proxxon) with the tungsten carbide and other wheels, but never on stone. I like the course grit for waste removal and roughing out, but it leaves a pretty rough surface. I sometimes switch to sanding discs using the grinder before going to rasps and other hand work for the finishing stage. My only experience with a 4 1/2 inch grinder is with course sanding discs for hogging out things like chair seats and that's plenty aggressive for what I do. Since those carbide discs are expensive, I might try the sanding discs first. I find the carbide discs leave a surface pattern in wood that's more pronounced than sanding discs, and sometimes they tend to follow the grain a bit. Jim

   You need diamond for hard stone. The carbide won't last long. Soft stone is ok.

   I've been using them for years and they are great on wood and other materials.  Buy some to try to see what you like as far as grit.

   Here's a link to the manufacturer, Kutzall.

   Thanks for the link. Which disc wheels have you tried- the "Original", "Extreme", or "Grit"? Do you know of a source for diamond grit disc wheels? Do you also use the Arbortech cutter? If so, how does that compare with the disc wheels?- Lyptus

   Have used most of the Kutzall wheels in dofferent grits. The better Arbortech cuts smoother. Kutzalls are rasp like. Arbortech is more aggressive. 

   http://www.sculpt.com/    for diamond wheels...there's other sources such as industrial supply, stone cutting, etc.

   You will just have to form your own opinion by buying and trying different grits and tools. There's carving forums out there as well and tons of already available info. Sharpen up your google skills. I never ask questions on the web. I just go to the answers I'm looking for and pick up additional info as I search.  Catalogs are a good way to learn about tools and products.
