Kennametal 3755689 CNMG543MP KCM15 Carbide Turning Insert

Product Description

The KENNAMETAL 3755689 is a CNMG543MP KCM15 grade carbide turning insert designed for external and internal turning, facing, and boring operations. Coated with a multilayer TiCN and Al2O3 CVD coating via MTCVD process, this insert is built for moderate-to-high wear resistance and toughness. It features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and an MP chip breaker geometry suited for roughing and medium machining passes. With four cutting edges and negative rake geometry, it delivers consistent performance across a range of metal-removal applications. Machinists and CNC lathe operators working with steel and stainless steel will find this insert well-matched to demanding production environments.

This insert is intended for turning, facing, and boring of steel, stainless steel, and superalloys including titanium-bearing workpiece materials. It is classified under primary workpiece material codes P and M, with secondary classification S for superalloys. The MP chip breaker geometry supports both roughing and medium machining cuts. The KENLOC series designation indicates compatibility with KENNAMETAL KENLOC-style insert holders that accept CNMG-style inserts secured by clamp or pin holding methods. This insert is appropriate for production CNC turning centers in both light industrial and heavy-duty shop environments.

Compatibility

Designed for use in KENNAMETAL KENLOC series toolholders that accept CNMG-style inserts with clamp or pin holding. Conforms to ANSI insert code CNMG543 and ISO insert code CNMG160612. Multi-use application includes turning, facing, and boring.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench or clamping tool specified by the toolholder manufacturer when securing the insert clamp or pin. Inspect the insert pocket and seating surface for chips or debris before seating a new cutting edge.
