diamond lathe inserts — FAQs

What are diamond lathe inserts used for?

How to choose the right grade for diamond lathe inserts?

Select the grade by your workpiece material and cutting condition. For continuous cuts choose a tougher grade; for high-speed or hard machining pick a harder PVD/CVD coated grade. Match the chip-breaker to your depth of cut and feed rate.
