Kennametal 2403013 Square End Mill 3/8 in 2 Flute Carbide

Product Description

The KENNAMETAL 2403013 is a solid carbide square end mill designed for high-precision milling operations in metalworking and machining environments. With a 3/8-inch cutting diameter, a 7/8-inch length of cut, and a 45-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action across a range of workpiece materials. The 2-flute geometry and right-hand spiral flute configuration make it well suited for slotting, profiling, and peripheral milling. Ground from KENNAMETAL K600 micrograin carbide, it offers the rigidity and edge retention expected in production and job-shop environments. This tool is installed and run by machinists, toolroom technicians, and CNC operators.

The 2403013 is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. Its single-end, centercutting design allows plunge entry as well as conventional side milling. The bright uncoated finish makes it appropriate for non-ferrous metals, plastics, and certain ferrous applications where coating interaction is a concern. The 3/8-inch shank diameter fits standard ER and straight-bore toolholders. No extended reach geometry is present, keeping runout and deflection low in standard-depth applications.

Key Features

• Solid K600 micrograin carbide construction for consistent edge retention
• 45-degree helix angle promotes efficient chip flow and reduced cutting forces
• Centercutting design enables direct plunge entry without pre-drilling
• 2-flute, right-hand cut and right-hand flute for standard milling operations
• Bright uncoated finish suitable for non-ferrous and dry-cutting applications
• Tight mill diameter tolerance of +0.000 / -0.002 inches for precise fit and finish

Compatibility

Designed as an OEM-style solid carbide square end mill in the KENNAMETAL AADF series, compatible with standard 3/8-inch straight-bore and collet toolholders used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the spindle before seating or removing the tool from the toolholder. Ensure the shank is fully engaged in the collet or chuck to the recommended insertion depth before tightening. Verify runout with a dial indicator after mounting; excessive runout accelerates tool wear and reduces surface finish quality.
