Iscar 6404105 GDMY840Y IC808 Grooving Insert 0.315 in

Product Description

The ISCAR 6404105 is a solid carbide grooving insert in the Cut-Grip series, designed for precision external and internal grooving operations on CNC lathes and turning centers. Carrying the GDMY840Y geometry with an IC808 manufacturer grade, this insert features a triple-layer PVD coating of AlTiN, TiAlN, and TiN for extended tool life across a broad range of workpiece materials. The cutting width is 0.315 inches (8.00 mm) with a maximum depth of cut of 0.157 inches. A positive rake angle of 7 degrees and a full-radius profile support clean chip evacuation and consistent groove geometry. The double-ended design delivers two usable cutting edges per insert.

This insert is suited for grooving, parting, and turning operations in production and job-shop turning environments. The IC808 grade and universal workpiece material classification make it applicable across steel, stainless steel, cast iron, high-temperature alloys, and non-ferrous materials. It is installed and indexed by a clamp-style insert holding method, standard in Cut-Grip compatible toolholders. The Y chip breaker geometry helps manage chip flow during moderate to high-feed grooving passes.

Installation Notes

Installation and indexing of grooving inserts should be performed by a qualified machinist or tooling technician with the machine in a full stop, lockout/tagout state. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten or substitute hardware. Inspect the insert pocket and clamping surfaces for chips or debris before seating the insert. Confirm insert orientation and engagement before resuming machine operation.
