Iscar 5507669 DNMG332VL IC908 Turning Insert 3/8 in Ic

Product Description

The ISCAR 5507669 is a solid carbide turning insert designed for precision CNC and manual lathe operations. Identified by the DNMG332VL designation, this insert carries the IC908 grade with a PVD-applied TiAlN coating for thermal resistance and edge durability at elevated cutting speeds. The insert features a 55-degree diamond shape (Shape Code D), a 3/8-inch inscribed circle, a 3/16-inch thickness, and a 1/32-inch corner radius. The Isoturn series VL chip breaker geometry promotes controlled chip flow across a range of turning applications. It measures 11.63 mm (0.458 inches) in length and weighs 0.176 pounds per package.

This insert is suited for turning operations on hard materials, stainless steels, cast irons, carbon steels, and high-temperature alloys. Primary workpiece material codes include K, M, and P, with secondary capability across H and S classifications per ISO 13399. Typical installation scenarios include external profile turning, facing, and light interrupted cuts in production shop environments. It is secured using a clamp-and-pin holding method, consistent with standard DNMG toolholder configurations.

Key Features

• IC908 grade with PVD TiAlN coating for heat and wear resistance in demanding cutting conditions
• 55-degree diamond insert shape for versatile external turning and profiling
• VL chip breaker geometry optimized for controlled chip evacuation
• 1/32-inch corner radius for improved surface finish on finish and semi-finish passes
• Maximum depth of cut of 3.50 mm (0.138 inches)
• Clamp and pin holding method compatible with standard DNMG insert pockets
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed as a replacement-style turning insert for DNMG332VL toolholder pockets. Compatible with workpiece materials classified under ISO codes K, M, P, H, and S, including hard materials and high-temperature alloys. Refer to your toolholder documentation to confirm pocket geometry and clamping compatibility before installation.

Installation Notes

Turning insert installation and replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully powered down and spindle locked. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to secure the insert — do not overtighten or use substitute fasteners. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Follow applicable shop safety procedures and machine-specific lockout/tagout protocols during tooling changes.
