Seco RNMG120400-MR4 883 Turning Insert

• 8 cutting edges per insert — index to a fresh edge instead of replacing the whole insert, lowering cost per edge
• Seco grade 883 Carbide Uncoated matched to the specified workpiece material range for predictable, repeatable tool life
• MR4 chipbreaker geometry controls chip formation through repeat production cycles, reducing chip-related downtime
• Seat size code 12 matches the corresponding Seco toolholder pocket
• 4.76 mm insert thickness for consistent seating in the toolholder pocket
