Typical Grinding Media Used
- SB-250 Original Grindstone, graded course
- DC-250 Diamond Wheel Course
- 60 grit ProEdge Zirconium Belt
- CBN wheel : <100 grit
- Very friable grindstone : 80 - 100 grit (possibly held on an angle grinder)
- Sandpaper : <100 grit (possibly held on an angle grinder)
Shaping the Tool - Stone working tools are reshaped based on their need (as dictated by the material to be carved).
Notes regarding shaping of tools with carbide inserts, when using a high speed grinder with a friable grindstone :
- DO NOT cool by dipping in water. This will cause the carbide to crack due to shocks.
- It is also recommended that you don't grind up to the final tool edge. The rough grit of the grindstone can create edges on the carbide which is easily susceptible to fractures.

As with shaping of tools with carbide inserts, when using a high speed grinder with a friable grindstone, DO NOT cool by dipping in water. This will cause the carbide to crack due to shocks.
