Kennametal 3760415 CNMG433MP KCM35 Turning Insert

Product Description

The KENNAMETAL 3760415 is a CNMG433MP KCM35 grade solid carbide turning insert designed for external turning, facing, and boring operations. It features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied via MTCVD process, which provides a balance of wear resistance and toughness suited to interrupted and continuous cuts. The insert measures 12.9 mm (0.5077 inches) in length with a 0.5-inch inscribed circle and a 3/64-inch (0.0469-inch) corner radius. The 80-degree diamond (rhombic) shape and negative rake geometry allow this insert to be indexed across 4 cutting edges, reducing per-edge tooling cost on production runs. Licensed machinists and CNC lathe operators select this insert for medium to roughing-depth applications on steel and stainless steel workpieces.

The 3760415 is engineered for primary use on steel (P-class) and stainless steel (M-class) workpieces, with additional suitability for superalloys and titanium. The MP chip breaker geometry is optimized for roughing and medium machining operations, managing chip evacuation during heavier cuts. Maximum depth of cut is 0.0492 inches (1.25 mm). The KENLOC series insert is held by clamp or pin methods in compatible toolholders, making it applicable across a wide range of CNMG-format turning tool bodies used in manual and CNC turning centers.

Key Features

• Multilayer CVD coating: TiN, TiCN, and Al2O3 via MTCVD process for high toughness and moderate-to-high wear resistance
• 80-degree diamond (rhombic) insert shape with negative rake and 0-degree relief angle for robust edge support
• 4 indexable cutting edges for extended tool life per insert
• MP chip breaker optimized for roughing and medium machining of steel and stainless steel
• Compatible with clamp and pin insert holding methods in KENLOC-style toolholders
• Conforms to ANSI (CNMG433) and ISO (CNMG120412) standards for broad toolholder compatibility

Compatibility

Designed for use in CNMG433-format toolholders compatible with the KENNAMETAL KENLOC clamping system. Conforms to ANSI insert code CNMG433 and ISO insert code CNMG120412. Suitable for clamp or pin holding methods in standard CNMG negative-geometry turning tool bodies.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine in a locked-out, zero-energy state before indexing or replacing inserts. Ensure the insert seat and clamping surfaces are clean and free of chips before seating the insert to prevent edge chipping from seating irregularities. Verify the correct torque specification from the toolholder manufacturer when tightening the clamping screw or pin. Do not exceed the maximum depth of cut rating for this insert geometry.
