KEUE CNC Brand 3 Year Warranty No Coating CNC Grooving Inserts MGMN200 MGMN250 MGMN300-IC MGMN400-DR KM241B Made in China
This MGMN series grooving insert covers cutting widths from 2.0mm to 4.0mm, with IC general-purpose chipbreaker for 200/250/300 sizes and DR enhanced chipbreaker for the 400 size. Matched with premium KM241B PVD-coated carbide grade, it is engineered for grooving, parting and slotting on steel and stainless steel via CNC lathes.
The KM241B grade adopts advanced nano TiCN-based PVD coating with excellent wear resistance and anti-adhesion performance, effectively suppressing built-up edge in continuous steel cutting. The IC geometry fits general feed ranges, while DR geometry ensures reliable chip evacuation in deep grooving operations.
Its double-edged design delivers 2 usable cutting edges per insert for solid cost efficiency in high-volume production. Precision machined to standard MGMN interface dimensions, it is fully compatible with common grooving tool holders and widely applied in automotive, machinery and hardware industries.
