Iscar 6172492 Carbide Turning Insert IC520N Ticn Tin

Product Description

The ISCAR 6172492 is a TPGX-style triangular carbide turning insert from the Isoturn series, designed for high-precision metal turning applications. It carries an IC520N grade with a PVD-applied TiCN plus TiN coating, delivering high wear resistance across steel, stainless steel, and hardened material workpieces. The insert measures 11.00 mm in length, features a 6.35 mm inscribed circle, a 3.18 mm thickness, and a 0.40 mm corner radius. Its positive side clearance geometry supports a finishing chip breaker operation. Licensed machinists and CNC turning center operators use this insert in production and job shop environments where consistent surface finish and tool life are critical.

This insert is suited for finish-turning operations on steel (P-class), stainless steel (M-class), and hardened materials (H-class). The L-style chip breaker geometry is optimized for light to moderate depths of cut, with a maximum depth of cut of 3.00 mm. It installs in right-hand toolholders accepting TPGX-style inserts with a 3.50 mm hole diameter and a 60-degree triangular seat. The ANSI insert code is TPGX221 and the ISO insert code is TPGX110304, making cross-referencing to standard toolholder catalogs straightforward.

Key Features

• IC520N carbide grade with PVD TiCN plus TiN multilayer coating for high wear resistance
• 60-degree triangular insert shape with positive 11-degree relief angle for reduced cutting forces
• L-style chip breaker optimized for finishing passes on steel, stainless steel, and hardened materials
• 6.35 mm inscribed circle (0.2500 inch) and 0.40 mm corner radius for tight-tolerance finishing
• Maximum depth of cut of 3.00 mm supports controlled, consistent material removal
• Conforms to ISO 13399 standards for tooling data representation

Compatibility

Designed for use in right-hand TPGX-style turning toolholders from the ISCAR Isoturn series and equivalent ANSI TPGX221 or ISO TPGX110304 compatible toolholder seats.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the correct torx or clamp screw specified for the toolholder to secure the insert without over-torquing the clamping mechanism. Inspect the insert seat and clamping hardware for chips or debris before installation to ensure proper seating and runout.
