Iscar 6404406 Grooving Insert TAGB1260Y IC8250 Sumo-grip

Product Description

The ISCAR 6404406 is a solid carbide grooving insert designated TAGB1260Y in the IC8250 manufacturer grade, part of the Sumo-Grip series. It delivers a 12 mm (0.4724 inches) cutting width and a maximum depth of cut of 6 mm (0.2362 inches), with a full depth-of-cut operating range of 5 mm to 10 mm. The insert features a positive rake geometry, a corner radius of 6 mm (0.2362 inches), and an Al2O3 PVD coating for extended wear resistance. It is a single-end, neutral-hand insert secured by a clamp-style holding method. Machinists and CNC programmers working in production turning environments will find this insert suited to precision grooving and parting operations.

This insert is designed primarily for grooving and parting applications on stainless steel and steel workpieces (ISO material codes M and P). It fits into compatible Sumo-Grip toolholders that accept the TAGB insert style in size 1260. The Y chip breaker geometry assists with chip control during interrupted cuts and continuous grooving passes. It is applicable in both manual and CNC turning centers where controlled chip evacuation and consistent groove width are required.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torx or hex key to secure the clamp to the manufacturer-specified procedure without over-torquing the clamping screw. Confirm insert seating and edge orientation before resuming cutting operations.
