Iscar 6400659 Grooving Insert IC20 Solid Carbide

Product Description

The ISCAR 6400659 is a solid carbide grooving insert in the Cut-Grip series, designed for precision external grooving and parting operations on CNC lathes and turning centers. This double-ended, neutral-hand insert features a 3.18 mm (0.1252 inch) cutting width and a maximum depth of cut of 13 mm (0.5118 inch). The uncoated IC20 carbide grade delivers consistent cutting performance across a broad range of workpiece materials. The positive rake geometry and 7-degree rake angle reduce cutting forces and promote chip control. Machinists and CNC operators working in production or job-shop environments install this insert into compatible Cut-Grip grooving toolholders.

This insert is suited for grooving and parting on both ferrous and non-ferrous workpiece materials, with a universal primary workpiece material rating covering material codes H, K, M, N, and S. It fits into standard Cut-Grip series toolholders and is applicable in light-to-medium duty turning operations on CNC and manual lathes. The P chip breaker style supports reliable chip evacuation during interrupted and continuous grooving cuts. The double-end design extends insert life by providing two usable cutting edges per insert.

Key Features

• Double-ended insert provides two cutting edges per insert body
• IC20 uncoated solid carbide grade rated for universal workpiece materials (H, K, M, N, S)
• 3.18 mm cutting width with 0.20 mm corner radius for controlled groove geometry
• Positive rake at 7 degrees reduces cutting forces and heat generation
• P-style chip breaker supports chip control in grooving and parting applications
• Compliant with ISO 13399 insert data standards for tooling integration

Compatibility

Designed for use in ISCAR Cut-Grip series grooving and parting toolholders accepting GIP-style inserts with insert size code 318020. The MSC/Manufacturer reference number for this insert is GIP 3.18-0.20.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine before changing inserts. Seat the insert fully in the toolholder pocket and confirm the clamping mechanism is secure before resuming operation. Inspect the pocket for debris or wear before installing a new insert to ensure proper seating and cutting-edge alignment.
