Kennametal 2403001 Square End Mill 0.25in 2 Flute Carbide

Product Description

The KENNAMETAL 2403001 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 0.25-inch mill diameter, a 0.75-inch length of cut (LOC), and a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action. With two spiral flutes and a bright, uncoated finish, this end mill is well-suited for general-purpose milling where coating is not required. It is manufactured to tight tolerances, with a mill diameter tolerance of +0.000 / -0.002 inches and a shank diameter tolerance of +0.00000 / -0.00035 inches. This tool is used by machinists and toolroom operators working on CNC mills, manual mills, and machining centers.

This end mill is appropriate for a wide range of milling tasks including slotting, profiling, and contouring on ferrous and non-ferrous materials. The AADF series from KENNAMETAL is built around the K600 material grade, which offers the hardness and wear resistance needed for consistent performance in production and job-shop environments. The single-end configuration and right-hand cutting direction make it a standard fit for conventional mill setups. The 2.5-inch overall length (OAL) and 0.25-inch shank diameter suit compact workholding and standard collet systems.

Key Features

• 0.25-inch mill diameter with tight diameter tolerance of +0.000 / -0.002 inches
• 45-degree helix angle for efficient chip flow and reduced cutting forces
• Two spiral flutes, right-hand cut, right-hand flute direction
• Solid carbide construction in K600 material grade for durability
• Centercutting design allows plunge entry into the workpiece
• Bright, uncoated finish suitable for applications where coatings are not required

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 0.25-inch collet and toolholder systems used in CNC and manual milling operations.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and locked out before changing or setting the tool. Seat the shank fully in the collet or toolholder and torque the retention hardware to the machine manufacturer's specified values. Inspect the flutes and cutting edges for damage before each use.
