The white wheels cut cooler, and are great for high carbon steel as in wood working chisels and plane irons but they aren't necessary for HSS, it will take a lot of heat. You won't be able to hold the cutter long before you get it hot enough to anneal it.
The wheels that come on grinders now are junk, not cheap but buy a good quality one and its night and day. 36 is good for roughing and I use a 120 for finishing, then hone on an oil stone,

Free advice is worth exactly what you payed for it.
