series

DD Excellent chip control and long tool life with high

pressure coolant Large holder lineup for turning, external grooving, cut-off and threading Unique coolant system for various machining applications

: Coolant hole

Advantages of internal coolant

Discharges coolant towards the cutting edge Internal coolant provides longer tool life and excellent chip control Extended tool life Improved chip control Wear resistance comparison (Internal evaluation) Chip control comparison (Internal evaluation) Internal coolant (7 MPa) External coolant (0.4 MPa) Internal coolant (7 MPa) External Coolant (0.4 MPa)
