Value Collection 112369336 TPG221 Carbide Turning Insert

Product Description

The VALUE COLLECTION 112369336 is a solid carbide turning insert with a TPG221 ANSI designation and manufacturer grade TCN55. It features a CVD-applied TiC and TiN multilayer coating for wear resistance and thermal stability during metal cutting operations. The insert carries a 60-degree triangular geometry with a flat-top chip breaker profile and a positive side clearance angle of 11 degrees. Inscribed circle measures 0.25 inches and corner radius measures 0.0156 inches (1/64 inch). Insert thickness is 0.125 inches. This insert is installed by machinists and CNC turning center operators in production and job-shop environments.

This insert is suited for turning applications on workpiece materials classified under ISO material groups M (stainless steel) and P (carbon and alloy steel), corresponding to carbide material grades C5, C6, and C7. The flat-top chip breaker design is appropriate for general-purpose turning passes where consistent chip control is required. The positive clearance geometry reduces cutting forces and is well-suited for finishing and light roughing passes on ferrous materials. Clamp-style insert holding is used with compatible TPG-style toolholders.

Key Features

• CVD-coated with TiC and TiN layers for extended tool life on steel and stainless workpieces
• 60-degree triangular insert shape (T) provides three usable cutting edges per insert
• Positive side clearance reduces cutting forces during turning operations
• Flat-top chip breaker (N) geometry supports consistent chip formation
• ANSI insert code TPG221 and ISO insert code TPG110304 for cross-reference compatibility
• Clamp-style holding method ensures secure seating in compatible toolholders

Compatibility

Designed for use in clamp-style turning toolholders that accept TPG-style inserts with ANSI size code 221 and ISO size code 110304. Compatible with ISO workpiece material groups M and P. Sold in multiples of 10 inserts.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC or manual turning centers. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamp hardware to seat the insert securely — do not overtighten by hand alone. Inspect the insert seat and clamp for chips or debris before seating a new insert to prevent premature edge failure.
