Iscar 6094895 Cutoff Insert GFR4J 6D IC-354 4mm Carbide

Product Description

The ISCAR 6094895 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured to the GFR insert style under ISCAR's Self-Grip series, it carries the IC-354 PVD-coated grade, a coating selected for its edge toughness and wear resistance on difficult-to-machine materials. The insert delivers a 4.00 mm (0.1575 inch) cutting width, a 6-degree right-hand lead angle, a 7-degree relief angle, and a 0.25 mm (0.0098 inch) corner radius. A J-style chipbreaker geometry promotes controlled chip formation and evacuation during cut-off cycles. The part is solid carbide throughout and is held in the toolholder by a clamp-style holding method.

This insert is intended for cut-off and grooving applications in production and job-shop turning environments. Its IC-354 PVD grade and J chipbreaker combination target stainless steel and general steel workpiece materials, matching ISO material codes M and P. Right-hand orientation suits standard OD turning setups. Machinists and CNC operators in metalworking shops are the primary installers. The insert is sold individually per package, with a minimum order quantity of 10 units, making it suited to toolroom stock replenishment or production cell kitting.

Key Features

• 4.00 mm cutting width (0.1575 inch) for precise parting and grooving
• IC-354 PVD-coated solid carbide grade rated for stainless steel and steel (ISO M and P materials)
• 6-degree right-hand lead angle with 7-degree relief angle for clean cut-off geometry
• J-style chipbreaker for consistent chip control during deep cut-off passes
• 0.25 mm corner radius minimizes stress concentration at the cut groove root
• Self-Grip series clamping system for secure, repeatable insert seating

Compatibility

Designed for use in ISCAR Self-Grip series toolholders that accept GFR-style cutoff inserts with a 4 mm insert size code. Compatible workpiece materials include stainless steel and steel per ISO material codes M and P. Conforms to ISO 13399 cutting tool data standards. Material grades C5 and C6 apply.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down the machine and lock out all spindle motion before changing inserts. Seat the insert fully into the Self-Grip toolholder pocket and verify the clamp engages without rocking or play before resuming cuts. Inspect the insert edge and corner radius for chipping at regular intervals, particularly when machining stainless steel, which accelerates edge wear.
