Value Collection ICP17540L Turning Insert TNMG222 TCN55

Product Description

The VALUE COLLECTION ICP17540L is a solid carbide turning insert designed for use in CNC and manual lathe operations. Manufactured to ANSI insert code TNMG222 and ISO insert code TNMG110308, this insert features a 60-degree triangular shape with a neutral relief angle and a TiN (titanium nitride) coating for improved wear resistance and surface hardness. The inscribed circle measures 0.25 inches, the insert thickness is 0.125 inches, and the corner radius is 0.03125 inches. Installed by machinists and tooling technicians, this insert suits turning applications where consistent edge geometry and coating durability are required.

This insert is suited for turning ferrous materials including steel and stainless steel, as indicated by primary workpiece material codes P and M. The TNMG style negative side clearance geometry is appropriate for medium to finishing cuts in both roughing and semi-finishing scenarios on conventional and CNC turning centers. It is held in place using clamp and pin insert holding methods, compatible with standard TNMG toolholders. The chip breaker designation is G, supporting chip control in a range of material removal conditions.

Key Features

• Solid carbide construction with TiN coating for extended tool life
• ANSI insert code TNMG222 and ISO insert code TNMG110308 for standardized toolholder compatibility
• 60-degree triangular insert shape provides three usable cutting edges
• Negative side clearance with neutral relief angle for stable, high-force cutting conditions
• Corner radius of 0.03125 inches for controlled surface finish on turned workpieces
• Compatible with clamp and pin holding methods in standard TNMG toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit insert for standard TNMG toolholders accepting ANSI size code 222 inserts with clamp and pin holding; verify toolholder specifications before installation.

Installation Notes

Turning insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle fully stopped. Use a torx or hex key appropriate for the toolholder clamping screw — do not overtighten the clamp, as this can crack the carbide. Inspect the toolholder seat and clamp for wear or debris before seating the new insert. Follow your facility's tooling change procedures and applicable machine safety standards.
