Kennametal 4050695 CNMG433RP KCU10 Carbide Turning Insert

Product Description

The KENNAMETAL 4050695 is a CNMG433RP indexable turning insert in the KCU10 grade, designed for productive metal removal on difficult-to-machine workpiece materials. The insert features a TiAlN coating applied via PVD process, which supports thermal resistance at the cutting edge during interrupted and continuous turning. The 80-degree diamond shape provides a strong nose geometry, while the RP chip breaker combines a chamfered and honed cutting edge with a 5-degree positive rake angle to manage chip flow and reduce cutting forces. With a 0.5-inch inscribed circle and a 0.0469-inch corner radius, the insert fits standard CNMG toolholders and is suited for medium to moderate finishing cuts. Licensed HVAC techs and plumbers work on different systems entirely — this insert is installed by machinists and CNC operators in production and job-shop environments.

The KENNAMETAL 4050695 is intended for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium. The KCU10 grade with PVD TiAlN coating is engineered specifically for these demanding material groups, identified by ISO material codes P, M, and S. Secondary applications cover cast iron and non-ferrous materials. The KENLOC series insert seats into clamp-and-pin style toolholders. It provides four usable cutting edges per insert, making it well-suited for high-volume production turning where edge economy matters. The ISO equivalent designation is CNMG120412RP.

Key Features

• TiAlN coating via PVD process for elevated thermal resistance and edge toughness
• RP chip breaker with chamfered and honed cutting edge for improved chip control
• 80-degree diamond insert shape with negative rake for strong, rigid cutting geometry
• Four cutting edges per insert — neutral hand orientation for flexible toolholder use
• Maximum depth of cut of 0.1691 inches for medium roughing to finishing passes
• Meets ANSI and ISO standards; ISO code CNMG120412RP for cross-reference ordering

Compatibility

Designed for use in CNMG-style clamp-and-pin toolholders within the KENLOC series. Compatible with turning, facing, and boring applications on steel, stainless steel, superalloys, and titanium as primary workpiece materials, with secondary compatibility for cast iron and non-ferrous materials per supplier data.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque on the clamping screw per the toolholder manufacturer specification — do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket and locating pin for wear or debris before seating a new insert.
