Iscar 5506626 Turning Insert Xcmt 070304-MF Carbide

Product Description

The ISCAR 5506626 is a solid carbide turning insert in the XCMT 070304-MF geometry, designed for precision external turning operations on CNC lathes and turning centers. The insert features a TiAlN coating applied via PVD process, delivering a combination of high wear resistance and thermal stability suited for interrupted and continuous cuts. With a corner radius of 0.016 inches (0.40 mm) and a negative side clearance, this insert is engineered for controlled chip formation on demanding workpiece materials. It carries the IC908 manufacturer grade, targeting general-purpose turning where consistent edge life and predictable performance are required.

This insert is suited for machining steel, stainless steel, cast iron, and special or super alloys, covering ISO material groups P, M, K, and S. It is typically applied in production turning environments where multiple material types are run across the same tooling setup. The MF chip breaker geometry supports finishing to medium-depth passes, making it a practical choice for shops running mixed-material jobs on modern CNC turning equipment. Licensed machinists and CNC tooling specialists are the primary end users for this insert.

Key Features

• TiAlN coating via PVD process for high wear resistance and thermal hardness
• IC908 grade provides a balance of wear resistance and toughness across multiple ISO material groups
• MF chip breaker geometry supports finishing to medium-depth cutting passes
• Negative side clearance (XCMT insert style) for stable seating in standard negative-rake toolholders
• Corner radius of 0.016 inches (0.40 mm) for controlled surface finish and edge integrity
• Conforms to ISO 13399 standard for cutting tool data representation

Compatibility

Designed as an OEM-style replacement insert for XCMT-style negative-rake turning toolholders compatible with ISO size code 070304 inserts. Specific toolholder compatibility should be verified against ISCAR toolholder documentation for the XCMT pocket specification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the turret indexed to a safe position before seating or replacing inserts. Use a torque wrench and the appropriate Torx or clamp screw driver to secure the insert per the toolholder manufacturer seating procedure. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper contact and prevent premature edge failure.
