Order example: MTQ 1010 D30 1.5 ISO MT7 First choice Alternative

To perform medium and large threads on
relatively deep work pieces.
To use overhang according to the application.
To perform deep threads at the bottom of the
application.
Advantages
Provides high rigidity and stability (anti-vibration).
Accomplishes deep threads in one pass.
Relatively low cutting forces due to short cutting
length.
Threads length up to 3D.
