Kennametal 2402999 Square End Mill 1/8 in 2 Flute Carbide

Product Description

The KENNAMETAL 2402999 is a solid carbide square end mill engineered for precision milling in demanding machining environments. Built to AADF series standards with a micrograin carbide grade K600, this tool delivers consistent cutting performance on ferrous and non-ferrous materials. The 1/8 inch mill diameter and 1/2 inch length of cut make it well suited for fine detail work, slotting, and profiling in tight geometries. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With a bright, uncoated finish, this end mill is ready to run without additional coating processes.

This end mill is designed for use in CNC machining centers and manual mills where close-tolerance work is required. The 1/8 inch shank diameter fits standard collet systems, and the 2 inch overall length keeps deflection low in short-reach setups. It is a single-end, center-cutting design, allowing plunge entry as well as conventional peripheral and slot milling. Machinists working in tool-and-die, mold, aerospace component, and general precision machining applications will find this geometry appropriate for finish passes and fine contouring work.

Key Features

• Solid carbide micrograin K600 grade construction for wear resistance and edge integrity
• 45-degree spiral helix angle for efficient chip evacuation and reduced cutting forces
• Center-cutting capability allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute configuration for standard spindle operation
• Bright uncoated finish suitable for direct use or as a base for additional coating if required
• Tight mill diameter tolerance of +0.000 / -0.002 inches for accurate finished dimensions

Compatibility

Designed as an OEM-style replacement or direct-use tooling for standard 1/8 inch collet or end mill holder systems used in precision CNC and manual milling applications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle at a full stop and machine power isolated. Ensure the collet or tool holder is clean and free of debris before seating the shank to the specified depth. Confirm runout with a dial indicator before cutting, as excessive runout will accelerate edge wear on small-diameter carbide tools. Follow shop safety procedures and machine manufacturer guidelines for speeds and feeds appropriate to the workpiece material.
