shallow drill inserts

Features

• Using the same types of inserts at the center and in the surrounding of drilling inserts,
  more easier for insert replacement.
• With a sharp cutting edge, reducing the vibration of the machining process,
• beneficial to the insert surface with low roughness.
• Optimized chip breaker structurer improve the cutting performance and chipping control,
• contribution to easy and fast cutting
• The combination of specific substrate and coating,
• well balanced the different wear patterns of center inserts and surrounding inserts.
