Frequently Asked Questions
WNMM indicates an 80° diamond-shaped, negative-rake turning insert with multiple cutting edges.
Both have an 80° diamond shape, but WNMM inserts are typically flat (no hole/chipbreaker designation), while WNMG includes chip-breaking geometry and a hole for secure clamping.
They can cut steel, stainless steel, cast iron, and hardened steels depending on the grade.
Yes, WNMM inserts are ideal for roughing and semi-finishing due to their strength.
Yes, available in CVD and PVD coatings for wear resistance, and uncoated for softer materials.
Absolutely. WNMM inserts are widely used in CNC turning centers and manual lathes.
Typically 6 to 8 cutting edges, depending on the insert’s design.
They are usually top-clamped or wedge-clamped into tool holders.
Yes, especially the coated and chipbreaker-designed variants, which ensure smooth chip evacuation.
