Iscar 6000485 Cutoff Insert Gfr 4-8D IC20 4.1mm

Product Description

The ISCAR 6000485 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured to the GFR insert style in size code 4, this single-end insert delivers a 4.1 mm (0.1614 inch) cutting width with an 8-degree right-hand lead angle and a 7-degree relief angle. The IC20 carbide grade is uncoated and suited for a broad range of workpiece materials. It seats and locks via a clamp-style holding method within the Self-Grip toolholder system, providing rigid, repeatable positioning at the cutting edge.

This insert is intended for cut-off and parting applications where consistent width control and tool rigidity are critical. The right-hand lead angle configuration directs cutting forces toward the chuck for improved stability during deep parting. The universal primary workpiece material designation covers steel, stainless, cast iron, non-ferrous, and heat-resistant alloys, making this insert adaptable across common turning applications in both job-shop and production environments. It is dimensioned and coded to ISO 13399 standards.

Installation Notes

Installation and replacement should be performed by a qualified machinist or tooling technician with the machine powered down and in a locked-out state. Seat the insert fully into the Self-Grip toolholder pocket and confirm the clamp is fully engaged before resuming operation. Inspect the insert seat and clamping surfaces for chips or debris prior to seating a new insert. Follow the toolholder manufacturer torque and clamping instructions for the specific Self-Grip body in use.
