Kennametal 1162735 TPU322 K68 Carbide Turning Insert

Product Description

The KENNAMETAL 1162735 is a solid carbide turning insert in the KENDEX series, designed for precision metal-cutting operations including turning, facing, and boring. It carries ANSI insert code TPU322 and ISO insert code TPU160308. The insert is uncoated (bright finish), features a triangular shape with a 60-degree included angle, and is manufactured to grade K68 — a solid carbide grade offering high to moderate wear-resistance and toughness across stainless steel, cast iron, aluminum, and non-ferrous workpiece materials. The flat top chip breaker geometry and positive rake angle support clean, controlled cuts in demanding applications.

This insert is suited for general machining of non-ferrous metals, superalloys, titanium, cast iron, and stainless steel in both production and job-shop environments. Its neutral hand orientation makes it adaptable across a range of toolholder setups. Typical applications include external turning, facing passes, and light boring operations on CNC lathes and manual turning centers. The insert is held in place by a clamp-style toolholder and is intended for use by machinists and tooling technicians.

Key Features

• Solid carbide K68 grade with high to moderate wear-resistance and toughness for stainless steel, cast iron, and non-ferrous materials
• Triangular insert shape with 60-degree included angle and 3 usable cutting edges
• Uncoated bright finish — no coating variables, consistent dimensional tolerance
• Positive rake angle with flat top chip breaker for efficient chip flow
• 11-degree relief angle with positive side clearance for reduced cutting forces
• Multi-use geometry supports turning, facing, and boring from a single insert

Compatibility

Designed for use with clamp-style toolholders accepting a TPU322 ANSI insert size (ISO size code 160308). Compatible with tooling systems specifying a 3/8-inch inscribed circle, 1/8-inch insert thickness, and 1/32-inch corner radius in a triangular seat geometry.

Installation Notes

This insert is installed and indexed by a qualified machinist or tooling technician using a clamp-style toolholder rated for the TPU insert geometry. Power down and lock out the machine spindle before seating or indexing the insert. Inspect the insert pocket and clamp for debris or wear before installation. Do not exceed the maximum depth of cut for this insert geometry as specified by the toolholder manufacturer.
