Back Machining

Back machining of holes, counter boring, chamfering, reaming with 2 types of tools, the indexable bar and the retractable cutter.

Key Points

Indexable insert bar: this tool need an indexable stop, the code is often M19
Retractable insert bar: the insert goes outside of its seat when the spindle rotation is inverted (M03/M04). Choose Inverted Rotation
