The CBN wheels are specifically designed to grind HSS.
These wheels are factory balanced, which makes grinders run very smooth. The grinding wheels have 1 1/2" face to use, they don't need any dressing therefore you won't have the mess of truing wheels or breathing the dust related to dressing wheels. There is no bluing of the steel, as these grinding wheels put very little heat into the tool. In a normal sharpening, you can still touch the end of the tool. You may have noticed in the pictures of the grinders, the guards have been removed. You can remove the guards with these wheels because there is no chance of them blowing up. With the guards off, you have better light and no shadows from the guards when sharpening your tools. You still should use eye protection. Suggest using 180 grit for our beading tools, skews and spindle gouges. We use 60 or 80 grit for shaping and sharpening our larger turning tools. They do produce a great edge.
