Hi, I want to start doing lapidary, I am also doing fused glass jewelry, I wander if I can use my Diamond Max 2 In 1 grinder (it have a flat grinder on it) for lapidary, and what discs I need to buy so it can mount on it?

Also im about to buy a tile saw machine for cutting fused glass bars, and wanted to buy one that I can cut slabs with it too. For the fused  glass bars I need to buy a good expensive Dimond blade, I still need to find out which one but that is not a problem, I want to ask should I use the same blade for the slabs? Which blade do I need for the slabs?
Thanks :-)

The flat lap will work but it will be slower than using a dedicated cab grinder.  You will need an assortment of disks starting at 100. You likely have a 260 grit with the unit.  Add 400, 600 and silicon carbide wetordry on a blank disk.  The center post will get in the way.  If you really get into it, you will soon want a dedicated lapidary machine.  Glass cutting blades will work for lapidary materials but the matrix is harder than what is normally best for harder materials like agate.  That means you will find yourself dressing the blade fairly often.  If you use a lapidary blade for glass it will wear down faster.

I don't need Dimond discs? For the grinder (the center post can be removed )
What blade will you recommend for me to buy to cut the slabs?
Thanks
