Value Collection TNMG160304NSA35 Turning Insert Carbide

Product Description

The VALUE COLLECTION TNMG160304NSA35 is a solid carbide, uncoated turning insert designed for external turning operations on CNC lathes and manual turning centers. Manufactured to ANSI code TNMG321 and ISO code TNMG160304, this neutral-hand insert features a 60-degree triangular shape with a negative side clearance geometry. The inscribed circle measures 3/8 inches (0.3752 inches decimal), and the corner radius is 1/64 inches (0.0157 inches decimal). Held in place via clamp and pin, it is suited for machinists and tool-and-die professionals working with ISO material group P workpiece materials such as carbon and alloy steels.

This insert is intended for medium to finish turning applications where an uncoated carbide grade is preferred. The I55 manufacturer grade falls within the C5 and C6 carbide material grades, making it appropriate for operations demanding a sharp, consistent cutting edge without coating-related buildup. The G-style chip breaker geometry assists in managing chip evacuation during continuous turning passes. Typical install scenarios include production turning shops, job shops, and maintenance machining environments where operators index inserts frequently.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the clamp; do not overtighten the clamping screw. Inspect the insert seat and clamp for debris or damage before seating the new insert to ensure proper contact and runout.
