Good starting point for most metal and wood applications. Aluminum Oxide is usually brown or reddish in color, but can be blue, green or yellow (which usually indicates the presence of a grinding aid/lubricant). It is durable with tough cutting edges, but it dulls during use. Aluminum Oxide is available in grits 24-600. LESS COMMON GRAINS
Green grit wheels do have application for grinding cast iron and some similar applications. Also,I used to run an old Fitchburg cylindrical that had a 20" green wheel, we spun down port tools after re-tipping them with new carbide in any broken pockets. Seems like I often eroded/dressed 1/8" -1/4" of that huge wheel in one night shift.

I like to go from rough grinding to 240 grit then hand rub anywhere from 220 to 2500 grit if its stainless and I am sending it to HT. O1, I used to go 60 - 80 - 120 and then hand sand to 220 for HT. Right now I am thinking, for 440 c, maybe benchgrinder, 80 grit belt grinder, 240 belt grinder and then HT then when it comes back go with new and worn 150 grit belts.
There are three principal types of bonds used in conventional grinding wheels. Each type is capable of giving distinct characteristics to the grinding action of the wheel. The type of bond selected depends on such factors as the wheel operating speed, the type of grinding operation, the precision required and the material to be ground.
Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min −1, although in high-speed grinding speeds of up to 5400m/min are achievable (Schey, 1987).The two most common grinding applications are cylindrical grinding and surface grinding.
