Iscar 5502326 Tpun 160308 IC20 Milling Insert Solid Carbide

Product Description

The ISCAR 5502326 is a solid carbide milling insert in the TPUN 160308 geometry, part of the ISCARMILL series. It carries an IC20 manufacturer grade and features an uncoated, bright finish suited for applications where coating is not required or where insert material alone provides the needed wear resistance. The insert has a triangular shape with a 60-degree included angle, a neutral hand orientation, a positive rake, and three usable cutting edges. The inscribed circle measures 0.3748 inches, thickness is 0.1250 inches, and the corner radius is 0.0315 inches (0.80 mm). It is designed for use by machining professionals in production milling operations.

This insert is intended for milling applications across a broad range of workpiece materials including stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is suited for use in face milling, shoulder milling, and general-purpose milling setups where a triangular single-sided insert with a positive rake geometry is appropriate. The flat-top chip breaker design and honed cutting edge style make it appropriate for moderate to aggressive material removal on challenging alloys. The insert is held in place via a clamp-style insert holding method.

Key Features

• Triangular insert shape with 60-degree included angle and 3 cutting edges
• IC20 solid carbide grade, uncoated (bright finish) for select material applications
• Positive rake geometry with honed cutting edge for reduced cutting forces
• Corner radius of 0.0315 inches (0.80 mm) for controlled edge definition
• Maximum depth of cut and cutting edge effective length of 0.5984 inches
• Neutral hand orientation for flexible toolholder compatibility
• Meets ANSI and ISO 13399 standards; ANSI code TPU 322 IC20, ISO code TPUN 160308

Compatibility

Designed as a replacement-style insert for ISCARMILL series toolholders and milling bodies that accept TPUN 160308 geometry inserts with a clamp-style holding method. Compatible with workpiece materials coded M, K, N, S, and H per ISO classification.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the milling spindle is fully stopped and the machine is in a locked-out, de-energized state before changing inserts. Seat the insert firmly against the toolholder pocket before tightening the clamp to the toolholder manufacturer's specified torque. Inspect the insert seat and clamp for wear or debris before installation to maintain proper insert positioning and edge repeatability.
