Iscar 6000836 GTN-3 Carbide Cutoff Insert 3.1mm

Product Description

The ISCAR 6000836 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It belongs to the Self-Grip series and carries the GTN-3 insert style with an IC20 uncoated carbide grade. The cutting width measures 3.1 mm (0.122 inches), making it suited for narrow parting cuts where precise groove width control matters. The insert features a neutral lead angle and a 7-degree relief angle, with a corner radius of 0.20 mm (0.0079 inches). It is held in place by a clamp-style insert holding method and is not designed for multi-use or double-end configurations.

This insert is intended for metal cutting applications in production and job-shop turning environments. The Self-Grip series clamping system secures the insert mechanically, eliminating the need for screws and allowing fast changeover. The IC20 carbide grade is an uncoated bright-finish material, classified under C2 and C3 material grades, appropriate for cutting a range of ferrous and non-ferrous workpiece materials in standard turning conditions. Machinists and CNC operators working with parting blades and grooving tool holders in the GTN-3 seat size will find this insert a direct fit.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Before changing inserts, ensure the machine spindle is fully stopped and the tool holder is secured in the turret. Seat the insert firmly into the Self-Grip pocket and verify the clamp engages completely before returning the tool to service. Follow the machine tool manufacturer and shop safety guidelines for insert handling, as carbide edges are sharp and brittle.
