You need 100 , 220 and 600 silicon carbide grit belts . As you need 600 grit belts in many degrees of worn states for doing different types of stone it is good to get extra of them . Ordering at least a dozen of each would be wise.

I use silicon carbide grits for my first stage polishing and they work well and are cheap.  Highly recommend them to start.

First of all, welcome aboard.  yes

I found this link. The belts are too fine, but you could contact Rio Grande and see if they have them in other grit sizes. http://www.riogrande.com/Product/203036
You could also contact 3M, the maker of this belt. I'm sure they have them in other grits, and could tell you who their distributers are.

He is asking who has 4 X 1 belts.   He also asked for diamond but probably should be using Silicon carbide.

LOL. Most of us old timers learned on SC wheels and belts. They didn't have diamond wheels yet. SC belts work just fine on hard materials like agate. They're slower than diamond, but if you're just learning to cab, you don't want to rush anyway.

One thing to remember about SC belts. When you think they're worn out, don't throw them away. They become the step between one grit and the next. This is especially true with the 600 grit belt. It becomes a pre-polish belt between 600 and polish.

If you use your grinding wheels properly sic works very well for agate . Use plenty of water and move back and forth across the belt to always keep the stone wet . Jakes advice is right on , use them until they die. Make sure you run them the way the arrow indicates ( on the inside of the belt) and if you take the drum off remount it according to the arrow on it.

Compare to a nova diamond .. about where would they be ?  .. like a 1200 or so ??

Thanks To all!! This is the stuff I need .The missus and I have picked up a lot of slabs and have a fair stash of tiger eye and looking for more in preparation for retirement . I am trying to spend the next few years getting my toys together but lapidary is one I want to get into as soon as possible. We have a couple of good shows a year here in Tulsa and we try to make them all and add to the rock box.next I want to start into jewelry on a small scale.I am a steel worker and fitter/welder by trade and a photographer by passion.When I add in wood working,rock grinding and silver smithing  I should be a pretty well rounded fellow in a few years.Oh yea almost forgot Metal detecting.
