Kennametal 7036146 CNMG432MV KCP25C Carbide Turning Insert

Product Description

The KENNAMETAL 7036146 is a CNMG432MV carbide turning insert in the KCP25C grade, designed for general-purpose metal cutting on CNC lathes and turning centers. It features a diamond-shaped insert body with an 80-degree included angle and a neutral hand orientation, making it suitable for a wide range of turning, facing, and boring operations. The insert carries a multilayer CVD coating of TiN, Al2O3, and TiCN applied over a carbide substrate, targeting wear resistance and thermal stability during cuts in steel and cast iron. The inscribed circle measures 0.5 inches and the corner radius is 0.0313 inches (1/32 inch). The MV chip breaker geometry uses a chamfered and honed cutting edge with a negative rake angle of 20 degrees.

This insert is engineered for primary workpiece materials classified as Steel (ISO P) and Cast Iron (ISO K). It suits roughing to semi-finish turning passes, facing cuts, and boring applications in both production and job-shop environments. The KENLOC series holding method uses a combination clamp and pin system, compatible with toolholders designed for CNMG-style inserts. The maximum depth of cut reaches 0.1691 inches. Machinists and CNC programmers working in high-volume steel or cast iron turning applications will find this insert grades well for interrupted and continuous cuts alike. It conforms to both ANSI and ISO standards, with ISO code CNMG120408MV.

Key Features

• CVD multilayer coating: TiN outer layer, Al2O3 mid layer, TiCN base layer for thermal and abrasion resistance
• Diamond insert shape (80-degree included angle) with 4 cutting edges for extended tool life
• MV chip breaker with chamfered and honed edge for controlled chip formation
• Negative rake geometry at 20 degrees suits heavy-duty and interrupted cutting
• Clamp and pin (KENLOC) holding method provides rigid insert seating
• Conforms to ANSI and ISO standards; ISO code CNMG120408MV

Compatibility

Designed as an OEM-style replacement and standard production insert for CNMG432 toolholders conforming to ANSI and ISO CNMG120408 specifications, used in turning, facing, and boring of steel and cast iron workpieces.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Ensure the machine spindle is stopped and the turret is fully indexed before changing inserts. Use the appropriate KENLOC clamp and pin toolholder to seat the insert; verify the insert is fully seated against the pocket locating surfaces before tightening. Inspect the chip breaker geometry and cutting edge condition visually before each use to confirm no micro-chipping is present.
