  1. Wheels that do not wear fast are for softer materials, the binding between grains is strong. For harder materials, say HSS, you need softer wheel, grains are held weakly and thus dulled grains are quickly replaced. I think there is a lot of cheating here with wheel material, i.e. Cheap wheels will use less of actual cutting material and more bonding. I was hoping the stall test would be done with same standard wheel, otherwise wheel quality is affecting the test for jet. Also i would hope there would be vibration test, main difference for me between cheap and expensive grinder is vibration. Cheap stuff vibrates a Lot.
