Iscar 6405125 Grooving Insert GIF800120E IC830 8mm

Product Description

The ISCAR 6405125 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Carrying the GIF800120E geometry and IC830 grade, this insert delivers an 8 mm cutting width and a maximum depth of cut of 4.80 mm. The IC830 substrate is PVD-coated with an AlTiN and TiN finish, optimizing edge toughness and wear resistance when machining difficult materials. It belongs to the Cut-Grip series and is installed using a clamp-style holding method. The double-ended design extends tool life by offering two usable cutting edges per insert.

This insert is engineered for machining superalloys and titanium alloys, making it well suited for aerospace, medical, and energy-sector component work where ISO material groups M, P, and S are commonly encountered. The positive rake geometry with a 7-degree rake angle reduces cutting forces on these demanding materials. A 1.20 mm corner radius provides controlled edge transition, and the E chip breaker geometry promotes effective chip evacuation in deep-groove applications. Machinists running tight tolerances on exotic alloys will find the IC830 grade well matched to the thermal and abrasion demands of these cuts.

Key Features

• 8 mm cutting width with a maximum depth of cut of 4.80 mm
• IC830 grade PVD-coated with AlTiN and TiN finish for heat and wear resistance
• Double-ended insert provides two cutting edges per piece
• Positive rake angle of 7 degrees reduces cutting forces on superalloys and titanium
• E chip breaker geometry promotes reliable chip control in grooving operations
• Clamp-style insert holding method for secure, repeatable seating in Cut-Grip toolholders

Compatibility

Designed for use in ISCAR Cut-Grip series clamp-style grooving toolholders that accept GIF-style inserts with an 800120 insert size designation. Confirmed for machining ISO material groups M, P, and S, covering steel, stainless steel, superalloys, and titanium.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine in a full stop, locked-out condition before changing inserts. Use the appropriate ISCAR clamping key to seat and secure the insert fully in the toolholder pocket before resuming cuts. Do not overtighten the clamp screw beyond the toolholder manufacturer specification. Inspect the pocket and clamp for chips or damage each time an insert is indexed or replaced.
