Iscar 6000881 Carbide Cutoff Insert GTN-4.8 IC20 4.8mm

Product Description

The ISCAR 6000881 is a carbide cutoff insert in the GTN-4.8 configuration, designed for parting and grooving operations on CNC lathes and turning centers. It carries manufacturer grade IC20 and features a 4.8 mm (0.189 inch) cutting width with a neutral lead angle and a 7-degree relief angle. The corner radius measures 0.28 mm (0.011 inch), helping control chip formation and edge wear during cut-off cycles. The insert is uncoated with a bright finish and is held in place by a clamping method. This is a single-end insert sold individually, with a minimum order quantity of 10 units. It is suited for machinists and tooling specialists working in precision metalcutting environments.

The ISCAR 6000881 is applied in cut-off and parting operations on bar stock and turned components. Its GTN-4.8 style seats into compatible Self-Grip toolholders, making it a standard choice for high-volume turning cells where consistent groove width and clean parting faces are required. The neutral hand and neutral lead angle make it adaptable to both right- and left-hand toolholder setups in typical turning applications. Machine shops running production runs on ferrous and non-ferrous materials in the C2 and C3 material grade range are the primary users of this insert.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or removing inserts. Use the appropriate torx or clamp-screw tool specified for the toolholder to avoid seat damage. Inspect the insert pocket and clamping surfaces for debris or wear before installing a new insert.
