Tungaloy 6850146 CNMA433 T5115 Carbide Turning Insert

Product Description

The TUNGALOY 6850146 is a solid carbide turning insert in the CNMA 433 series, designed for precision metal cutting in turning, facing, and boring operations. It carries a multilayer CVD coating of TiCN, Al2O3, and TiN under the T5115 manufacturer grade, targeting cast iron and similar K-group workpiece materials. The insert features an 80-degree diamond shape, a neutral hand orientation, and a honed cutting edge, delivering consistent chip control across a broad range of cutting conditions. With 4 available cutting edges per insert, it offers extended service life for production environments.

This insert is suited for CNC turning centers and manual lathes where cast iron components require reliable, repeatable stock removal. Its flat-top chip breaker geometry with a zero-degree rake angle and negative clearance is well matched to heavy interrupted cuts and continuous turning passes on ferrous materials. Compatible with standard CNMA-style toolholders accepting clamp or pin holding methods, it fits into existing setups without modification.

Key Features

• CVD multilayer TiCN / Al2O3 / TiN coating under T5115 grade for cast iron performance
• 80-degree diamond insert shape with 4 cutting edges for maximum tool utilization
• Honed cutting edge style reduces micro-chipping on interrupted cuts
• Neutral hand orientation suitable for both left- and right-hand toolholders
• Clamp and pin holding compatibility with standard CNMA-series pockets
• Flat-top chip breaker geometry supports turning, facing, and boring applications

Compatibility

Designed as a direct-fit replacement for CNMA 433 industry-standard insert pockets. Compatible with CNMA-style toolholders accepting clamp or pin holding methods. Meets ANSI and ISO standards for CNMA insert geometry.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified hardware when seating the clamp or pin to avoid insert movement during cutting. Inspect the toolholder pocket and seating surfaces for wear or debris before installing a new insert.
