Phenolic Finishing Point
Manufacturer: Diamond Pacific

You can finish extremely hard stone with Phenol Points, especially fire agate free-forms and jade carvings. Tools must be charged with diamond compound. The more the tool is used, the more the diamond becomes embedded in the point.
Use any grit combination, but 325, 1200 and 50,000 will do a good job in most cases. Use a separate tool for each grit. Avoid contamination. Use lubricant not water. Tools are most effective using a flex-shaft machine at 500 RPM.
Shank size: 3mm
