Diamond turning tools
A diamond turning tool carries one single crystal diamond with one cutting edge. On a lathe it leaves a bright, smooth surface in the final pass, so the part needs no polishing afterwards. Bulunmaz makes these tools in natural diamond and MCD, as standard shapes or to your drawing.

Common questions
- What is a diamond turning tool?
- A lathe tool with a single crystal diamond cutting edge, used for the final bright pass on non-ferrous metals and plastics.
- Natural diamond or MCD?
- Both give a mirror finish. Which is better depends on your material and the shape of the edge. Tell us the job and we'll recommend one.
- Can it be resharpened?
- Yes. A worn edge is relapped and the tool is used again, usually several times.
