Tungaloy 6780929 Cnmg 433 Th T9225 Turning Insert

Product Description

The TUNGALOY 6780929 is a CNMG 433 TH indexable turning insert in grade T9225, featuring a multilayer CVD coating of TiN, TiCN, and Al2O3 TiN. Manufactured from solid carbide with a negative rake angle of -20 degrees, it delivers high wear resistance and toughness across steel, stainless steel, and cast iron workpieces. The insert carries an 80-degree diamond (rhombic) shape with a 0.0472-inch corner radius and a 0.5000-inch inscribed circle. With four cutting edges and a TH chip breaker geometry, it is suited for roughing, medium machining, and heavy machining operations. Licensed CNC machinists and turning specialists are the primary installers of this insert.

This insert is designed for external turning, facing, and boring operations in a wide range of production and job-shop environments. Its P15 and P25 material grades position it for moderate to heavy cuts in steel and stainless steel, while the K-category wear resistance extends its use to gray and ductile cast iron. The negative side clearance and CNMG geometry make it compatible with standard negative-rake toolholders. The TH chip breaker profile handles interrupted and continuous cuts at higher feed rates typical of roughing passes.

Key Features

• CVD multilayer coating: TiN / TiCN / Al2O3 / TiN for extended tool life in steel and cast iron
• 80-degree diamond insert shape (CNMG) with negative rake for robust edge strength
• Four usable cutting edges maximize cost-per-edge value
• TH chip breaker rated for roughing, medium machining, and heavy machining
• Maximum depth of cut up to 0.2362 inches for aggressive material removal
• Secured by clamp or pin holding methods; compatible with standard CNMG toolholders

Compatibility

Designed as an OEM-style replacement for CNMG 433 negative-rake indexable toolholders accepting clamp or pin retention; conforms to ANSI and ISO standards under ANSI code CNMG433 and ISO code CNMG120412.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Always index or replace inserts with the machine powered off and spindle locked per shop lockout/tagout procedures. Use the correct torque wrench for clamp screws - refer to the toolholder manufacturer's specification sheet for fastener torque values. Inspect the insert pocket and seating surface for chips or debris before seating a fresh cutting edge to prevent premature edge failure.
