Tungaloy 6780827 Cnmg 433 Tm T9225 Turning Insert Carbide

Product Description

The TUNGALOY 6780827 is a CNMG 433 TM indexable turning insert in the T9225 grade, designed for general-purpose metal cutting on CNC lathes and turning centers. The insert features a CVD-applied multilayer coating - TiN, TiCN, and Al2O3 - that provides wear resistance and heat control at the cutting zone. With a 0.5 inch inscribed circle, 0.0469 inch corner radius, and a negative rake angle of -6 degrees, this insert suits medium to semi-finishing passes. Four usable cutting edges per insert extend tool life and reduce cost per edge. The TM chip breaker geometry manages chip flow across a range of depths and feed rates. Licensed machinists and CNC operators install this insert in standard CNMG-style toolholders with clamp or pin retention.

This insert is rated for primary workpiece materials that include steel (ISO code P), stainless steel (ISO code M), and cast iron (ISO code K), with material grades P15 and P25 covering a broad range of hardness and feed conditions. It is suited for turning, facing, and boring operations in both production shops and job shops. The neutral hand orientation allows use in right- or left-hand toolholder setups. Maximum depth of cut is 0.1969 inches, making this insert appropriate for medium roughing and finishing applications where consistent chip control is required.

Key Features

• CVD multilayer coating: TiN outer layer, TiCN mid-layer, Al2O3 thermal barrier for extended edge life
• 80-degree diamond (CNMG) insert shape with negative rake angle for strong cutting edge geometry
• TM chip breaker designed for turning, facing, and boring across steel, stainless, and cast iron
• Four usable cutting edges per insert for maximum value per unit
• Clamp and pin compatible retention for secure seating in standard CNMG toolholders
• Conforms to ANSI and ISO standards for drop-in replacement into existing setups

Compatibility

Designed for use in standard CNMG-style toolholders with clamp or pin insert retention. Compatible with ISO code P, M, and K workpiece materials - specifically steel, stainless steel, and cast iron - at material grades P15 and P25. Conforms to ANSI and ISO CNMG 433 TM dimensional standards.

Installation Notes

Installation is performed by a licensed machinist or CNC operator. Power down and lock out the machine before seating or indexing the insert. Verify the toolholder pocket is clean and free of chips before installing; debris under the insert seat will affect runout and edge life. Do not exceed the rated maximum depth of cut of 0.1969 inches for this insert geometry.
