Compatibility and ordering
Match the cutting head model and the current ceramic ring's outer diameter, thread pitch, height and contact layout before ordering. Nominal M11, M8 and M14 thread labels alone do not establish compatibility. Send a clear photo of the cutting head nameplate and old ring if you need help selecting a model. The product photo illustrates the range; appearance may vary by variant.
Courier freight is confirmed by destination, weight and carton size. We normally ship by DHL, UPS or FedEx with tracking.
If you are unsure about compatibility, send the cutting-head model, source model, part code or dimensions before ordering. Custom, special-order and opened optical parts are handled according to the agreed order terms.
