Iscar 6094135 GTN4 IC328 Carbide Cutoff Insert 4.1mm

Product Description

The ISCAR 6094135 is a solid carbide cutoff and grooving insert designed for use in Self-Grip style toolholders. Manufactured to the GTN4 insert style with a 4.1 mm (0.1614 inch) cutting width, this insert carries the IC328 grade designation and is finished with a PVD coating process. The IC328 grade is suited for a range of material classes including C2, C3, C5, and C6. With a neutral lead angle and a 7-degree relief angle, it is built for consistent chip control during parting and grooving operations on CNC lathes and turning centers. Licensed machinists and toolroom operators are the primary installers of this insert type.

This insert is applied in grooving and parting operations on turning equipment where a Self-Grip compatible toolholder is in use. The single-end configuration and clamp-style holding method make it appropriate for production and job-shop environments where repeatability and toolholder compatibility are priorities. The 0.24 mm corner radius supports controlled chip formation in both light and moderate stock-removal passes across a variety of workpiece materials.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine spindle fully stopped and the toolholder secured in the turret. Use the appropriate insert clamp key or torx wrench specified for the Self-Grip toolholder being serviced. Inspect the insert pocket seat for chips or debris before seating the new insert. Follow the toolholder manufacturer guidelines for clamp torque and insert orientation to avoid premature edge failure.
