Recommended Specifications:

General Purpose	WA46H8V		WA	The most friable grain - easy cutting action
Steel < 55Hrc	WA46K7V		WAB (AZ)	Fast and cool cutting
Steel > 55Hrc	AS46H8V		PA	Tough but friable
Stainless Steel (soft) 300 series	PA46J8V		RA	Tougher than PA - good for chromium steel
Stainless Steel (hard) 400 series	AZ46H8V		WAG	Excellent form holding - cool grinding
Nickel Alloys	WAG60F15V		GC	For carbide and non-ferrous applications
HSS & Tool Steel	AS360I13V		AS	Submicron crystal structure gives long life with maximum performance
Carbides / Tungsten	GC60J7V
Non-ferrous Metals	GC60J7V

Vertical Surface Grinding 

Segments used on rotary table grinding machines.
The face of the wheel (segment, cylinder, cup) does the grinding.
The workpiece is on a reciprocating or rotary table
