Iscar 6003526 Carbide Cutoff Insert 1.5mm Pentacut

Product Description

The ISCAR 6003526 is a solid carbide cutoff and parting insert in the PentaCut series, designed for screw-lock toolholders that accept the PENTA 24R150 insert style. The insert features a 1.5 mm (0.0590 inch) cutting width, a 15-degree right-hand lead angle, and a Z-style chipbreaker geometry. The substrate is a submicron-grain solid carbide manufactured to grade IC1008, finished with a PVD-applied TiN and TiAlN coating for wear resistance across a broad range of workpiece materials. Licensed machinists, tool-and-die shops, and CNC turning centers operators are the primary installers of this insert type.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, P, and S. That range includes hardened steels, cast irons, stainless steels, non-ferrous alloys, general steels, and heat-resistant superalloys. Typical applications are parting-off and cutoff operations on CNC lathes and turning centers in production and job-shop environments. The screw-lock holding method provides rigid clamping and repeatable indexing without requiring special torches or adhesives.

Key Features

• Solid carbide IC1008 grade substrate with submicron grain structure for edge toughness
• PVD-coated with TiN and TiAlN for thermal resistance and extended tool life
• 1.5 mm (0.0590 inch) cutting width with a 0.05 mm corner radius for precise parting operations
• 15-degree right-hand lead angle with Z chipbreaker geometry for controlled chip evacuation
• Screw-lock insert holding method for secure, repeatable seating in compatible toolholders
• Conforms to ISO 13399 tooling data standards for integration with CAM and tool management systems

Compatibility

Designed for use in PentaCut series screw-lock toolholders that accept the PENTA 24R150 insert style. Suitable for parting and cutoff operations across ISO material groups H, K, M, N, P, and S.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine in a fully stopped, de-energized state. Use the correct torx or hex key specified by the toolholder manufacturer to seat the screw-lock clamp — do not over-torque. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Follow the toolholder manufacturer's setup sheet for correct overhang and approach angle to match the 15-degree lead angle geometry of this insert.
