FAQ
What is the ZEPF NANOPAL coating? NANOPAL is a specialized surface coating applied by Helmut Zepf GmbH to improve wear resistance and reduce friction on dental instrument tips, extending the functional life of the insert.
Which handles does this insert fit? It threads into compatible Helmut Zepf interchangeable-insert handles. Verify the thread specification against your handle before clinical use.

Design Notes
Nanopal® coating: the black crystalline nano-coating raises surface hardness to 4,500 Vickers — the highly tempered cutting edge stays aggressive and sharp far longer and does not need resharpening after each curettage, while the scratch-resistant black surface is easy to clean and prevents light reflections.
