Kennametal 1161919 Turning Insert CPMT32.52LF KC730

Product Description

The KENNAMETAL 1161919 is a CPMT32.52LF solid carbide turning insert with a PVD-applied TiN coating and KC730 grade designation. It features an 80-degree diamond (rhombic) insert shape, a neutral hand orientation, and a screw-on holding method. The inscribed circle measures 3/8 inches (0.3750 inches), the corner radius is 1/32 inches (0.0313 inches), and the insert length is 9.67 mm (0.3808 inches). The LF chip breaker geometry is designed for finishing and light machining operations. With a positive rake angle of 5 degrees and a positive side clearance, this insert delivers high wear resistance across a range of workpiece materials. It carries both ANSI and ISO standard designations.

This insert is suited for turning, facing, and boring operations on steel, stainless steel, cast iron, and superalloys including titanium. The KC730 grade provides high to moderate wear resistance and toughness in P, M, and K workpiece material categories, making it a reliable choice for precision finishing cuts in production and job-shop environments. Secondary workpiece material compatibility extends to M and S material codes. The maximum depth of cut is 1.25 mm (0.0492 inches), keeping this insert in its intended finishing range.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine before changing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamp screw to the toolholder manufacturer specification. Inspect the insert pocket for wear, debris, or damage before each insert change to maintain accurate seating and surface finish quality.
