The updated UT4 tip with a 8mm of diamond coating. Used when you need a side-cutting action as well as an end-cutting action. Slightly less activity at the end of the tip than a standard UT4, but with the ability to flare out the walls of a troughing groove or access. These have less activity than the CT4-D tips, but are narrower and can work deeper into the canal.
Activity Level: 2
