KEUE CNC High Hardness HRC45-60 Quenching Steel Titanium Alloy Grooving Inserts MGMN300 MGMN4004-GU KM6210 3 Year Warranty China
This MGMN series grooving insert covers MGMN300 and MGMN4004-GU models with GU-type high-performance chipbreaker geometry, matched with premium KM6210 carbide grade and signature rainbow PVD coating. It is purpose-built for grooving, parting and slotting of high-hardness quenched steel and titanium alloy workpieces on CNC lathes.
The KM6210 carbide substrate delivers excellent hot hardness and edge toughness, while the iridescent nano-composite PVD coating enhances wear resistance and thermal stability under high cutting temperatures. The optimized GU geometry reduces cutting forces and ensures reliable chip control even in difficult-to-cut hardened and titanium materials.
Precision machined to standard MGMN interface dimensions, these double-edged inserts fit most common clamp-type grooving tool holders for fast indexing and reduced downtime. They are widely applied in aerospace, mold, tooling and automotive industries for high-value hardened metal component machining.
