Iscar 6403361 GEPI25WT005WT IC908 Grooving Insert

Product Description

The ISCAR 6403361 is a solid carbide grooving insert carrying the manufacturer designation GEPI25WT005WT in grade IC908. It is designed for the Cut-Grip clamping system and features a TiAlN coating applied by a PVD process, which delivers strong wear resistance and thermal stability during interrupted and continuous grooving operations. The insert has a cutting width of 0.0984 inches (2.50 mm), an overall length of 0.3937 inches (10.00 mm), a corner radius of 0.0020 inches (0.05 mm), and a positive rake angle of 8 degrees. Machinists and tool-and-die professionals working on CNC lathes and turning centers install this insert type as part of precision grooving setups.

This insert is suited for grooving operations across a broad range of workpiece materials. The IC908 grade and universal primary workpiece material designation make it applicable to steel (P), stainless steel (M), cast iron (K), hardened materials (H), and heat-resistant superalloys (S). The WT chip breaker geometry supports chip control in precision grooving and parting applications typical in both production turning and job-shop environments. The double-end configuration allows the insert to be flipped for extended tool life per insert.

Compatibility

Designed for use with ISCAR Cut-Grip series toolholders that accept the GEPI insert style in size 25WT005. Confirm toolholder seat dimensions and clamping compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before seating or removing the insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer - do not overtighten the clamping screw. Inspect the insert seat and clamping surfaces for debris or damage before each insert change to maintain accurate positioning and surface finish.
