Kennametal 7093475 Cnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093475 is a CNMG-style carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. It features an AlTiN coating over a KCU10B carbide grade substrate, providing thermal resistance and edge durability across a range of work materials. The diamond-shaped insert body carries an 80-degree included angle with a neutral hand orientation and an MP chip breaker geometry. Four usable cutting edges are available per insert, reducing per-edge tooling cost in production environments. Licensed machinists, CNC operators, and toolroom technicians install these inserts in compatible CNMG toolholders.

This insert is suited for turning applications requiring a 0.40mm (0.0157 inch) corner radius and consistent chip control. The MP chip breaker geometry handles a broad range of feeds and depths, making it applicable in general-purpose finish and semi-finish turning. The AlTiN coating supports dry or minimal-coolant cutting strategies where elevated cutting temperatures are anticipated. Typical applications include turning ferrous and non-ferrous materials in automotive, aerospace, and general machining environments.

Key Features

• CNMG insert style with 80-degree diamond shape (C) and neutral hand orientation
• AlTiN coating on KCU10B carbide grade for elevated thermal and wear resistance
• MP chip breaker geometry for reliable chip control across varied feeds and depths
• Four usable cutting edges per insert maximize cost efficiency in production runs
• 0.40mm (0.0157 inch) corner radius for general finish and semi-finish turning
• Insert thickness of 0.1875 inches (3/16 inch) per CNMG standard geometry

Compatibility

Designed as a direct-fit replacement for standard CNMG 431 toolholders and boring bars accepting CNMG-style inserts with a C insert shape code, N clearance code, and M tolerance code.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians using an appropriate torx or hex key to seat the insert securely in the pocket. Ensure the toolholder pocket and clamping mechanism are clean and free of chips before seating the insert. Rotate to a fresh cutting edge rather than re-indexing a worn edge to maintain dimensional accuracy. Follow the machine tool manufacturer and insert grade recommendations for speeds, feeds, and coolant strategy.
