Iscar 6090231 Cutoff Insert 3mm DGR3000ZS15D IC908

Product Description

The ISCAR 6090231 is a solid carbide double-ended cutoff and parting insert from the Do-Grip series, designed for precision grooving and parting-off operations on CNC lathes and turning centers. The insert carries the DGR3000ZS15D geometry with an IC908 manufacturer grade and a PVD coating applied over a submicron carbide substrate. The cutting width measures 3.00 mm (0.1180 inches), the maximum depth of cut reaches 18.00 mm (0.7087 inches), and the overall insert length is 20.40 mm (0.8031 inches). A right-hand lead angle of 15 degrees and the ZS chipbreaker geometry work together to control chip flow and reduce lateral cutting forces during parting operations.

This insert is suited for parting and grooving applications across a broad range of workpiece materials. The IC908 grade with PVD coating is rated for universal application, covering material groups H, K, M, P, and S per ISO classification — meaning it handles steel, stainless steel, cast iron, hardened materials, and superalloys in typical production turning environments. It is held in place by a clamp-style toolholder compatible with the Do-Grip system. The double-ended configuration allows the insert to be indexed, extending useful tool life per insert. This insert is typically used by machinists and CNC turning professionals in job shop and production settings.

Key Features

• Solid carbide construction with submicron carbide substrate for rigidity and wear resistance
• IC908 grade with PVD coating rated for universal workpiece material groups (H, K, M, P, S)
• 3.00 mm cutting width with maximum depth of cut of 18.00 mm
• Right-hand orientation with 15-degree lead angle for controlled chip direction
• ZS chipbreaker geometry for effective chip management during parting and grooving
• Double-ended insert design for extended tool life per unit
• Clamp-held Do-Grip series insert — conforms to ISO 13399 tooling data standards

Compatibility

Designed for use with Do-Grip series clamp-style toolholders that accept the DGR insert style. Compatible across primary workpiece material groups H, K, M, P, and S as defined by ISO classification. Consult the ISCAR Do-Grip system toolholder specifications to confirm pocket and clamp compatibility before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine in a locked-out, zero-energy state. Use the correct ISCAR Do-Grip clamping tool to seat and secure the insert — do not force the insert into the pocket by hand or with improvised tools. Verify insert seating and clamp torque per the toolholder manufacturer specifications before resuming cutting. Inspect the insert pocket and clamping screw for wear or damage whenever replacing inserts.
