Iscar 6404047 Grooving Insert 2.5mm Min-cut IC908

Product Description

The ISCAR 6404047 is a solid carbide grooving insert in the Min-Cut series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the MIFR10250020 insert size code and is finished with a PVD-applied TiAlN coating under the IC908 grade designation. The neutral hand orientation makes it suitable for straight-in grooving cuts. With a 2.5 mm cutting width and a maximum depth of cut of 9 mm, this insert handles a broad range of groove profiles. It is installed and replaced by machinists and toolroom technicians working in production and job-shop turning environments.

This insert is engineered for universal workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range spans steel, stainless steel, cast iron, high-temperature alloys, and hardened materials. The IC908 PVD-coated grade is well suited for finishing and semi-finishing passes where edge sharpness and coating adhesion matter. The clamp or screw holding method means it seats in compatible ISCAR Min-Cut toolholders designed for the MIFR insert style. Typical applications include external grooving, undercut profiling, and shallow parting on bar-fed and chucked workpieces.

Compatibility

Designed for use with ISCAR Min-Cut series toolholders that accept the MIFR insert style and MIFR10250020 insert size. Verify toolholder seat dimensions and clamping method before installation.

Installation Notes

Insert replacement should be performed with the machine powered down and all axes at rest. Use the appropriate torx or hex key specified by the toolholder manufacturer when securing with a clamp screw; do not overtighten the clamp or seat screw. Inspect the insert pocket for chips or debris before seating the new insert, and confirm the insert is fully seated before resuming cuts. Toolroom technicians and CNC machinists should follow their facility lockout/tagout procedures before any tooling change.
