MGMN300-T KM242 PVD-Coated Carbide Insert for Steel Stainless Steel Processing HRC Replaces Imported PC5300 OEM Turning Tool
This MGMN300-T grooving insert comes with a 3.0mm standard cutting width and T-type precision chipbreaker, paired with the premium KM241 PVD-coated carbide grade. As a cost-effective substitute for imported Korloy PC5300 inserts, it is engineered for grooving, parting and slotting operations on carbon steel and stainless steel via CNC lathes.
The KM241 grade features advanced nano TiCN PVD coating with outstanding anti-adhesion and wear resistance, effectively suppressing built-up edge and crater wear during continuous steel cutting. The optimized T-type chipbreaker ensures consistent chip formation and smooth evacuation across a wide range of feed rates and cutting depths.
Machined to standard MGMN mounting dimensions, this double-edged insert fits most common clamp-type grooving tool holders for fast indexing and reduced downtime. It delivers performance comparable to imported PC5300 at a lower cost, and is widely applied in automotive, machinery, hardware and valve manufacturing.
