Iscar 6400263 Grooving Insert 8mm IC20 Solid Carbide

Product Description

The ISCAR 6400263 is a solid carbide grooving insert in the Cut-Grip series, designed for external grooving and parting operations on CNC lathes and turning centers. Carrying the IC20 uncoated carbide grade, this neutral-hand insert delivers a cutting width of 8 mm and supports a maximum depth of cut of 27 mm. The double-ended design extends service life by providing two usable cutting edges per insert. A positive rake angle of 7 degrees and an F-style chip breaker promote controlled chip flow across a broad range of workpiece materials. Installation is performed by machinists and toolroom technicians using compatible Cut-Grip toolholders.

This insert is suited for universal application across multiple material groups, including cast iron, non-ferrous alloys, stainless steel, steel, and high-temperature alloys, corresponding to ISO material codes H, K, M, N, and S. It is commonly used in precision turning operations requiring consistent groove width and depth in production and job-shop environments. The self-grip holding method seats the insert securely in the toolholder without additional clamping hardware, supporting rigid setups at productive feed rates.

Compatibility

Designed for use with Cut-Grip series toolholders that accept the GIF 800E080 insert size. Compatible across ISO material groups H, K, M, N, and S as designated by the manufacturer. Verify toolholder pocket specification against ISO code GIF 8.00E-0.80 before installation.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing any insert. Confirm the toolholder pocket is clean and free of chips or debris prior to inserting the cutting edge. Do not exceed the manufacturer-rated depth of cut or feed rate for the selected workpiece material.
