Features
By adopting TRI-Cooling technology optimized for small diameter drills, the coolant discharge volume has been more than doubled compared to conventional models.
Chip evacuation performance and cutting heat dissipation performance are greatly improved, greatly contributing to life stability.

Use
For small diameter hole machining.
Work material: steel, stainless steel, cast iron.
