What is the difference between the green and the black SiC grinding wheels? There does not seem to be much price difference. What would the advantages of one over the other be? Thanks for any info,
Mike

Oops,sorry about the lack of extra info! It was late, I was tired, but here ya go. The black wheel on my Lortone is labeled Cascade Lapidary Wheel, premium grade, distributed by Lortone. Also, here is a link with pricing. www.kingsleynorth.com/skshop/search_results2.php?catID=856The info on the link doesn't tell me much, says something about the bond of the grit. Thanks; Mike

That really interesting Mike can't answer your question directly cause I've never used one
I’ve only used the green wheels, I've 2 Ones a Cascade & the other a Gemini brand
My feeling is that the bonding in the black wheel might be tougher & the wheel would last longer But may load up easier
I’m really interested knowing & look forward to getting hand on experience till then hopefully some one else will be able to supply that info

Stolen from tootoo.com....
"Black silicon carbide is produced from quarts sand and coke or coal as its main raw material, melted at high temperature in an electric arc furnace. Its hardness is between fused alumina and synthetic diamond, while mechanical intensity is higher than fused alumina. It is brittle and sharp. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc. It is also widely used as refractory material and Metallurgical additive.
Green silicon Carbide is produced in the same way of Black silicon Carbide except some difference in raw material. Its crystallization has higher purity and hardness. Green silicon Carbide is suitable for processing hard alloy, metallic and non-metallic materials with hard and brittle feature such as copper, brass, aluminum, magnesium, jewel, optical glass, ceramics, etc."
(I was to lazy to put it in my own words ;D )

Thanks Dr Joe! So. It looks like when it is time to replace my wheel, maybe sooner, I would benefit from getting the green wheel then. Like the color better too,lol.

I sure made the mistake of not reading these posts before buying two new wheels. Put one on yesterday (black) and it doesn't cut worth a darn.
