Seco 16NL12UN,CP500 Turning Insert

• 3 cutting edges per insert — index to a fresh edge instead of replacing the whole insert, lowering cost per edge
• Seco grade CP500 Carbide PVD matched to the specified workpiece material range for predictable, repeatable tool life
• 0.15 mm corner radius for the specified finish and strength balance
• Seat size code 16 matches the corresponding Seco toolholder pocket
