Kennametal 1162185 CCGT431HP K313 Carbide Turning Insert

Product Description

The KENNAMETAL 1162185 is a solid carbide, uncoated turning insert in the CCGT431HP K313 grade, designed for precision finishing operations on CNC and manual lathes. It carries an 80-degree diamond (rhombic) shape with a positive rake angle of 15 degrees and a 7-degree relief angle, giving it a sharp, free-cutting geometry suited to light chip loads. The inscribed circle measures 0.5 inches, insert length is 0.5077 inches, and thickness is 0.1875 inches. The HP chip breaker geometry is optimized for finishing passes at tight tolerances. The K313 grade offers high wear resistance and is suited to stainless steel, cast iron, aluminum, and other non-ferrous materials.

This insert is intended for turning, facing, and boring applications across a range of workpiece materials including non-ferrous metals, superalloys, and titanium. It is commonly used in production and job-shop environments where fine surface finishes and close dimensional tolerances are required. The screw-on holding method provides secure clamping in compatible CCGT-style toolholders. With two cutting edges per insert and a neutral hand orientation, it offers flexibility across multiple setup configurations. Licensed machinists and CNC operators in precision machining, aerospace, and general metalworking will find this insert well suited to finishing-stage work.

Compatibility

Designed as an OEM-style screw-on replacement insert for CCGT431-style toolholders accepting an 80-degree diamond insert with a 0.5-inch inscribed circle and screw-on mounting. Conforms to ANSI code CCGT431 and ISO code CCGT120404.

Installation Notes

Installation is performed by trained machinists or CNC setup technicians. Before changing inserts, ensure the machine is powered down, the spindle is fully stopped, and all axes are locked. Use the manufacturer-specified torx or hex key to seat the clamping screw to the toolholder specification without over-torquing. Inspect the insert pocket and seating surfaces for chips or debris before installing the new insert to ensure proper seating and runout.
