Kennametal 1112574 Milling Insert ANGT1003PPERLG KC725M

Product Description

The KENNAMETAL 1112574 is a solid carbide milling insert in the ANGT series, designed for use in milling operations on steel, stainless steel, superalloys, and titanium. It carries the KC725M manufacturer grade and features a three-layer PVD coating of TiN, TiCN, and TiN for extended tool life and heat resistance. The insert measures 0.4090 inches in length, 0.2677 inches wide, and 0.1417 inches thick, with a 0.5000-inch inscribed circle diameter. A 0.0197-inch corner radius and a 30-degree rake angle support efficient chip formation in demanding cut conditions. Licensed machinists and CNC tooling technicians install this insert in compatible milling toolholders.

This insert is suited for milling applications on P, M, and S workpiece material classifications per ISO standards, covering carbon and alloy steels, austenitic and ferritic stainless steels, and difficult-to-machine superalloys and titanium alloys. It is a right-hand insert with the LG chip breaker geometry, making it appropriate for moderate to aggressive material removal in production milling environments, both horizontal and vertical machining centers. The maximum depth of cut is 0.5000 inches. It is sold individually but subject to a minimum order quantity of 5 units.

Key Features

• KC725M grade solid carbide substrate with PVD-applied TiN/TiCN/TiN multilayer coating for wear and heat resistance
• ANGT parallelogram insert shape with 85-degree included angle and 0-degree relief angle
• LG chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium
• 30-degree rake angle promotes efficient chip evacuation in high-alloy and hard materials
• Right-hand cutting orientation with screw-mount insert holding method
• Corner radius of 0.0197 inches (0.50 mm) for controlled edge engagement

Compatibility

Designed for use in ANGT-series compatible milling toolholders accepting inserts with a 0.5000-inch inscribed circle diameter, insert size code 1623, and screw-mount retention. Suitable for material grades C5, C6, and C7 per cutting tool classification. ISO code ANGT1003PPERLG.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Use the appropriate torx or hex key to secure the mounting screw to the toolholder manufacturer's specified method without over-torquing the carbide insert. Inspect the toolholder pocket and seating surface for chips or wear before installing a new insert.
