Kennametal 7036170 TNMG331MV KCP25C Carbide Turning Insert

Product Description

The KENNAMETAL 7036170 is a TNMG331MV carbide turning insert in the KCP25C grade, designed for general-purpose metal cutting on CNC and manual lathes. The insert features a triangular shape with a 60-degree included angle, a negative rake geometry, and a chamfered and honed cutting edge style. The multilayer CVD coating stack — TiCN, Al2O3, and TiN — delivers wear resistance and thermal stability across a wide range of cutting conditions. With 6 usable cutting edges and neutral hand orientation, this insert suits high-volume production environments where insert economy matters. It is intended for installation by machinists and toolroom professionals on standard KENLOC-style clamp-and-pin toolholders.

This insert is rated for turning, facing, and boring operations on steel and cast iron workpieces (ISO material groups P and K). The MV chip breaker geometry is suited to medium-duty cutting passes where chip control is a priority. The 3/8-inch inscribed circle and 3/16-inch thickness place it in a mid-size insert class commonly found on medium to large bore toolholders. A maximum depth of cut of approximately 0.2163 inches supports both roughing passes and semi-finish work depending on feed and speed selection.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torque wrench and clamp hardware specified for the KENLOC toolholder to avoid insert rocking or premature edge failure. Inspect the insert pocket for chips or debris before seating a new cutting edge, and confirm the insert is fully seated and the clamp is secure before resuming cuts.
