Iscar 6095399 Milling Insert Gsfn 3J IC908 Carbide

Product Description

The ISCAR 6095399 is a solid carbide milling insert in the GSFN 3J configuration, designed for use in self-grip style milling cutters. It carries the IC908 manufacturer grade and features a TiAlN coating applied via a PVD process. The insert has a rectangular shape with a 90-degree included angle, a 0.1180-inch cutting edge effective length, a 0.1181-inch inscribed circle diameter, and a 0.0098-inch corner radius (0.25 mm). With a positive rake and a 7-degree relief angle, this single-sided, single-cutting-edge insert is suited for high-performance metal removal in demanding applications. Licensed ISCAR tooling specialists and CNC machining technicians are the typical end users.

This insert is intended for milling operations across a broad range of workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, and H). The J chip breaker geometry supports controlled chip formation during these cuts. It is engineered for use in the SGSF cutter series and is sold individually with a minimum order quantity of 10 units. This insert fits production machining environments where insert consistency and coating durability are critical to cycle time and tool life.

Key Features

• IC908 grade solid carbide with submicron material grade for wear resistance in difficult-to-machine alloys
• TiAlN PVD coating supports high cutting temperatures and extended tool life in steel and stainless steel
• Positive rake and 7-degree relief angle reduce cutting forces and improve surface finish
• Sharp cutting edge style with 0.0098-inch corner radius minimizes workpiece deflection
• Self-grip insert holding method provides secure, repeatable seating in compatible cutter bodies
• Neutral hand orientation allows flexible application in standard self-grip toolholders

Compatibility

Designed for use with the SGSF cutter series. Conforms to ANSI and ISO 13399 standards with ANSI code GSFN 3J IC908 and ISO code GSFN 3J.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC tooling technician with the machine powered down and the spindle locked. Use the appropriate torx or hex key to seat the insert fully in the pocket before applying clamping torque. Inspect the insert pocket for chips or debris before each insert change. Do not force the insert into the pocket, as damage to the self-grip mechanism can affect runout and surface finish.
