Iscar 5502905 Turning Insert Tnmg 332-PP Solid Carbide

Product Description

The ISCAR 5502905 is a solid carbide uncoated turning insert in the TNMG 332-PP geometry, part of the Isoturn series. Designed for precision metal turning operations on CNC and manual lathes, this triangular insert features a 60-degree included angle, a positive rake geometry, and a PP chip breaker configuration. The uncoated IC20 grade solid carbide substrate provides consistent edge sharpness across a range of workpiece materials. At 0.65 inches in length with a 3/8-inch inscribed circle, this insert fits standard TNMG-style toolholders used in industrial machining environments. It is installed by machinists and CNC operators in production and job-shop settings.

This insert is suited for turning cast iron, stainless steel, non-ferrous metals, and high-temperature alloys, corresponding to ISO workpiece material groups K, M, and N. The PP chip breaker geometry promotes controlled chip formation in light-to-medium depth-of-cut applications, with a maximum depth of cut of 0.1181 inches (3.00 mm). Typical applications include finish and semi-finish turning passes where precise chip control and dimensional accuracy are required. This insert is packaged individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide uncoated IC20 grade substrate for consistent cutting-edge integrity
• TNMG 332-PP geometry with positive rake and PP chip breaker for controlled chip evacuation
• 60-degree triangular insert shape provides up to 6 usable cutting edges per insert
• 1/32-inch corner radius (0.0315 inches) suitable for finish and semi-finish turning passes
• Maximum depth of cut of 3.00 mm (0.1181 inches) in standard turning operations
• Conforms to ISO 13399 standard for cutting tool data representation

Compatibility

Designed as a direct-fit replacement for TNMG 332-style toolholders that accept clamp and pin insert holding methods. Compatible with ISO workpiece material groups H, K, M, N, and S. Refer to ISCAR Isoturn series toolholder documentation to confirm seat and clamp compatibility before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified for the toolholder to secure the insert without cracking the carbide substrate. Inspect the insert seat and chip breaker pocket for debris before seating a new insert.
