Kennametal 1310718 CCGT21505LF KC5010 Carbide Turning Insert

Product Description

The KENNAMETAL 1310718 is a solid carbide turning insert designed for precision metal removal in finishing and light machining operations. It carries the ANSI designation CCGT21505LF and ISO designation CCGT060202, and is manufactured in grade KC5010 with a PVD-applied TiAlN coating. The insert features an 80-degree diamond (rhombic) shape, a positive rake angle of 5 degrees, a 7-degree relief angle, and a honed cutting edge style. The inscribed circle measures 0.25 inches, insert length is 0.2539 inches, and the corner radius is 0.0079 inches. It mounts via screw-on holding method and delivers two usable cutting edges per insert.

This insert is suited for turning, facing, and boring operations on steel, stainless steel, superalloys, titanium, and cast iron workpieces. The LF chip breaker geometry targets finishing and light machining passes where tight surface finish tolerances are required. The KC5010 grade is characterized by high to moderate wear resistance combined with moderate toughness, making it effective across ISO material groups P, M, K, N, and S. It is a neutral-hand insert, compatible with screw-on style toolholders designed for CCGT geometry inserts.

Key Features

• Grade KC5010 solid carbide with PVD TiAlN coating for extended tool life on steel and stainless steel
• LF chip breaker geometry optimized for finishing and light machining cuts
• 80-degree diamond insert shape with positive rake and positive side clearance for reduced cutting forces
• Honed cutting edge style for improved edge stability on difficult materials including superalloys and titanium
• Screw-on mounting with 0.1102-inch hole diameter for secure, repeatable insert indexing
• Maximum depth of cut of 0.0492 inches suitable for precision finishing passes

Compatibility

Designed for use in screw-on style toolholders accepting CCGT geometry inserts per ANSI and ISO standards, suitable for external turning, facing, and boring applications across ISO material groups P, M, K, N, and S.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine fully de-energized and the spindle locked. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque range — consult the toolholder documentation. Inspect the insert pocket and seating surface for chips or debris before seating the insert, as contamination can affect repeatability and edge life. Follow all applicable shop safety procedures when handling carbide inserts, as edges are sharp and the material is brittle.
