Carbide grinder - use for tool steel and ENCO quality
Harbor Freight sells the 46727 Chinese grinders for less than Enco sometimes, but shipping and tax can change the relative total cost. I have a local HF store and have seen the grinders on sale for around $130. I use a green wheel on one end of my Baldor for roughing, and a diamond on the other end for sharpening carbide.
