Iscar 6402158 Grooving Insert IC20 Solid Carbide 2mm

Product Description

The ISCAR 6402158 is a solid carbide grooving insert designed for precise external and internal grooving operations on CNC lathes and turning centers. Part of the Cut-Grip series, this insert carries the GIG200020G geometry and IC20 uncoated carbide grade. It features a 2 mm cutting width, a maximum depth of cut of 3 mm, and a 0.20 mm corner radius. The double-ended design extends usable tool life by providing two cutting edges per insert. A positive rake angle of 7 degrees and G-style chip breaker support effective chip evacuation across a wide range of workpiece materials.

This insert is suited for grooving, parting, and profiling operations in general machining environments. The IC20 uncoated grade and universal primary workpiece material classification make it applicable across steel, cast iron, stainless steel, non-ferrous metals, and high-temperature alloys. It is sized at 200020 and is compatible with ISCAR Cut-Grip toolholders designed for that insert size. Typical users include CNC machinists and toolroom operators running production or job-shop turning work.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Use the appropriate torx or hex key to engage the clamping mechanism and seat the insert fully against the pocket locating surfaces. Verify insert orientation and overhang before resuming cuts, and confirm that the toolholder size matches the 200020 insert size designation.
