Cargo Carbide DNGA CBN Insert is a CBN cutting insert designed for precision CNC turning applications where high hardness, dimensional consistency, and controlled cutting performance are required. The DNGA geometry provides a compact diamond-shaped cutting configuration suitable for precision turning and finishing operations.

CBN, or Cubic Boron Nitride, is a cutting-tool material commonly used for machining hardened ferrous materials and other difficult-to-machine applications. DNGA CBN inserts can be used for operations such as external turning, internal turning, finishing, profiling, and precision machining, depending on the specific CBN grade and machining conditions.

The indexable design allows the cutting edge to be replaced when required while retaining the existing tool holder. Cargo Carbide DNGA CBN inserts are suitable for compatible DNGA tool holders on CNC lathes and turning centers.
