Kennametal 3749360 CNMG432FW KCP10 Carbide Turning Insert

Product Description

The KENNAMETAL 3749360 is a solid carbide turning insert in the CNMG432FW geometry, coated with a multilayer TiCN and Al2O3 CVD coating under the manufacturer grade designation KCP10. It belongs to the KENLOC series and is designed for external and internal turning operations on CNC and manual lathes. The insert measures 12.9 mm (0.5077 inches) in length with a 0.5-inch inscribed circle and a 1/32-inch corner radius. The negative rake geometry with a honed cutting edge and FW chip breaker delivers controlled chip formation across a range of depths of cut, with a maximum depth of cut of 1.25 mm. This insert is installed by machining professionals in production and job-shop environments.

The CNMG432FW KCP10 insert is suited for turning, facing, and boring applications on steel and cast iron workpieces, aligning with ISO material groups P and K. The 80-degree diamond insert shape and neutral hand orientation make it adaptable to a wide range of toolholder setups. With four available cutting edges per insert, it offers extended service life per unit. The KENLOC clamping system uses a combined clamp and pin holding method, providing rigid tool engagement during interrupted and continuous cuts.
