Kennametal 1183313 TPG322 KC850 Carbide Turning Insert

Product Description

The KENNAMETAL 1183313 is a solid carbide turning insert in the TPG322 geometry, part of the KENDEX series. It carries a multilayer CVD coating of TiC, TiCN, and TiN over a carbide substrate graded KC850, targeting moderate to high wear resistance combined with toughness. The insert features a triangular shape with a 60-degree included angle, a 3/8-inch inscribed circle, a 1/32-inch corner radius, and a flat-top chip breaker with a positive rake and positive side clearance. With three usable cutting edges and a neutral hand orientation, it suits turning, facing, and boring operations across a range of workpiece materials. Licensed machinists and CNC turning center operators are the primary installers.

This insert is designed for general-purpose metal cutting on CNC lathes and turning centers in both production and job-shop environments. Primary workpiece materials include steel and stainless steel, with additional applicability to cast iron and special or super alloys. The KC850 grade delivers a balance of wear resistance and toughness appropriate for moderate interrupted and continuous cuts. The flat-top geometry keeps chip control straightforward across those material classes. Maximum depth of cut is 0.0492 inches (1.25 mm), making this insert well suited to finishing and light semi-finishing passes rather than heavy roughing.

Key Features

• KC850 grade CVD multilayer TiC/TiCN/TiN coating for wear resistance and toughness across steel, stainless steel, cast iron, and super alloys
• TPG322 geometry with 60-degree triangle shape and three cutting edges for cost-efficient edge utilization
• Positive rake and positive side clearance reduce cutting forces during light to moderate cuts
• Flat-top chip breaker provides predictable chip control in turning, facing, and boring applications
• 1/32-inch corner radius minimizes workpiece surface stress while maintaining edge strength
• Meets ANSI and ISO standards; ANSI code TPG322, ISO code TPG160308

Compatibility

Designed as an OEM-style replacement insert for KENDEX-series toolholders accepting TPG322-style triangular carbide inserts. Confirm toolholder pocket geometry, clamp style, and clearance code P compliance before installation.

Installation Notes

This insert is installed and changed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before any insert change. Seat the insert fully in the pocket and secure with the appropriate clamp or screw torqued to toolholder manufacturer specifications. Inspect the cutting edge and corner radius condition at regular intervals; do not continue cutting with a chipped or worn edge, as doing so risks workpiece damage and toolholder wear.
