Color Hard Grooving Blade MGMN200/250/300/400/500-PF 4860 High Stainless Steel

MGMN-PF Grade 4860 Color-Hardened CNC Grooving Inserts for High Hardness Stainless Steel

This MGMN series color-hardened grooving insert covers cutting widths from 2.0mm to 5.0mm, featuring PF-type precision chipbreaker geometry and premium Grade 4860 carbide substrate. With signature color-reinforced PVD coating, it is purpose-built for grooving, parting and slotting of high-hardness stainless steel via CNC lathes.

The advanced color-hardened PVD coating delivers exceptional surface hardness, abrasion resistance and thermal stability, effectively suppressing built-up edge and flank wear in continuous high-hardness stainless steel cutting. The optimized PF geometry ensures steady chip formation and smooth evacuation across wide feed and depth ranges.

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 deliver reliable high-efficiency performance and are widely applied in automotive, energy, hardware and precision machinery industries.
