The position of the rubber handle is chosen so that even small end mills can be sharpened perfectly.
One side with the coarse 50micron 300 diamond grit for rough grinding and one side with the fine 25micron 600 diamond grit for fine grinding.
Can be used with lapping fluid or water.
The optional matching stone holder holds the small grindstone securely on the workbench and its thickness provides enough space to grind end cutters - without bumping into them.
