Seco CNMG120404W-MF4 TM2501 Turning Insert

• 4 cutting edges per insert — index to a fresh edge instead of replacing the whole insert, lowering cost per edge
• Seco grade TM2501 Carbide CVD matched to the specified workpiece material range for predictable, repeatable tool life
• MF4 chipbreaker geometry controls chip formation through repeat production cycles, reducing chip-related downtime
• 0.4 mm corner radius for the specified finish and strength balance
• Seat size code 12 matches the corresponding Seco toolholder pocket

Seco Turning Inserts (carbide and cermet grades in C, D, R, S, T, V, and W shapes with precision tolerance classes and chipbreaker geometries) deliver reliable, repeatable performance for CNC and conventional lathe turning of steel, stainless steel, cast iron, aluminium, titanium, and superalloy workpieces in production and job shop environments.
