Iscar 6400549 Grooving Insert IC20 Solid Carbide

Product Description

The ISCAR 6400549 is a solid carbide grooving insert from the Cut-Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. This double-ended insert carries manufacturer grade IC20, an uncoated solid carbide grade suited for universal workpiece materials. It delivers a cutting width of 1.96 mm and a maximum depth of cut of 3.00 mm, with a positive rake angle of 7 degrees and a corner radius of 0.15 mm. The neutral hand orientation makes it straightforward to position in compatible Cut-Grip toolholders without favoring a left or right cut direction. It is installed by machinists and CNC turning technicians in production and job-shop environments.

This insert is applied in grooving, parting, and profile turning operations across a broad range of workpiece materials. Its primary workpiece material compatibility spans multiple ISO material groups, including cast iron, stainless steel, steel, non-ferrous metals, and heat-resistant superalloys, corresponding to ISO codes H, K, M, N, and S. The double-end design extends usable tool life per insert, making it a practical choice in high-volume turning applications where minimizing insert changeover time matters. It is well suited for light to medium grooving passes in both production turning and tool-room work.

Compatibility

Designed for use with ISCAR Cut-Grip series toolholders that accept the GIP insert style, size code 196015. Compatible with ISO material groups H, K, M, N, and S, covering cast iron, stainless steel, general steel, non-ferrous, and superalloy workpieces. Also referenced as GIP 1.96-0.15 by the manufacturer.

Installation Notes

Insert seating and clamping should be performed with the machine spindle fully stopped and all energy sources locked out per your facility lockout-tagout procedure. Inspect the insert pocket and clamping mechanism for debris or wear before seating the insert to ensure proper contact and prevent micro-movement during cutting. Use the torque specification provided by the toolholder manufacturer for the clamping screw — do not overtighten, as this can fracture the carbide body. Consult your toolholder documentation and applicable shop safety standards before returning the machine to service.
