Kennametal 1182969 Turning Insert SPG633 KC850 Carbide

Product Description

The KENNAMETAL 1182969 is a solid carbide turning insert in the SPG633 geometry, part of the KENDEX series. It features a multilayer CVD coating of TiC, TiCN, and TiN under the KC850 grade, a combination that delivers moderate wear resistance and toughness across a broad range of workpiece materials. The insert has a square shape with a 90-degree included angle, a 3/4 inch inscribed circle, a 3/64 inch corner radius, and a flat-top chip breaker. With four usable cutting edges and a positive side clearance, it suits high-volume turning, facing, and boring operations. Licensed machinists and CNC programmers specify this insert for stable, repeatable cuts in steel and stainless steel applications.

This insert is designed for turning, facing, and boring operations on CNC lathes and turning centers. Primary workpiece materials are steel and stainless steel, with the KC850 grade also rated for cast iron and special or super alloys at moderate wear-resistance and toughness levels. The flat-top geometry with a honed cutting edge and positive rake delivers consistent chip control at moderate cutting parameters. The KENDEX series design accommodates standard clamp-style insert holders, making it a direct fit for common production turning setups in both job-shop and high-volume environments.

Key Features

• KC850 grade with multilayer CVD coating: TiC, TiCN, and TiN for broad material coverage
• Square SPG633 geometry with 90-degree included angle and positive side clearance
• 3/4 inch inscribed circle and 3/64 inch corner radius for stable, accurate cuts
• Four cutting edges per insert maximize tooling value in production runs
• Flat-top chip breaker with honed cutting edge for predictable chip formation
• Rated for turning, facing, and boring on steel, stainless steel, cast iron, and super alloys

Compatibility

Designed for use in clamp-style insert holders that accept SPG633 geometry inserts. Compatible with ANSI and ISO standard tooling systems. Conforms to ANSI insert code SPG633 and ISO insert code SPG190412. Suitable for KENDEX series holder configurations.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct clamp torque specified by the holder manufacturer to avoid insert fracture or movement during cuts. Inspect the insert pocket and clamp for wear or debris before installing a new edge.
