Kennametal 1162363 CCMT432LF KC850 Turning Insert

Product Description

The KENNAMETAL 1162363 is a solid carbide turning insert designated CCMT432LF in the KC850 grade, designed for precision metal removal on CNC lathes and turning centers. It features an 80-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and a 7-degree relief angle, giving it a sharp, free-cutting geometry suited to finishing and light machining passes. The multilayer CVD coating stack — TiC, TiCN, and TiN — delivers moderate wear resistance combined with toughness across a range of workpiece materials. The LF chip breaker geometry controls chip flow effectively at lighter depths of cut, keeping the work zone clear during close-tolerance turning operations.

This insert is appropriate for turning, facing, and boring operations on steel, stainless steel, and cast iron, and it is rated for use on special and super alloys as well. The neutral hand orientation and screw-on holding method make it compatible with standard CCMT-style toolholders. Typical applications include finishing passes on medium to large-diameter workpieces where surface finish and dimensional accuracy are the primary goals. Maximum depth of cut is 1.25 mm (0.0492 inches), confirming its role in light, precision cutting rather than heavy roughing.

Key Features

• KC850 grade with multilayer CVD coating (TiC, TiCN, TiN) for wear resistance and toughness
• 80-degree diamond insert shape with positive rake and positive side clearance for sharp cutting action
• LF chip breaker geometry optimized for finishing and light machining operations
• Neutral hand orientation with screw-on insert holding method
• Two cutting edges per insert for extended tool economy
• Honed cutting edge style for edge stability on coated carbide
• Conforms to ANSI and ISO standards (ANSI: CCMT432, ISO: CCMT120408)

Compatibility

Designed as an OEM-style replacement for CCMT432-style screw-on turning insert seats in standard CCMT toolholders rated for 0.5-inch inscribed circle inserts. No specific toolholder model compatibility was stated in the product data.

Installation Notes

Installation is performed by a machinist or CNC tooling technician using the appropriate Torx or hex key for the screw-on insert clamp. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamp screw to avoid seating errors that can affect surface finish and tool life. Inspect the insert pocket for wear or debris prior to seating a new insert.
