Accupro 12464374 Square End Mill 0.024 in 2 Flute Carbide

Product Description

The ACCUPRO 12464374 is a solid carbide square end mill designed for precise milling operations in metal, composite, and hard plastic workpieces. Built to stub-length proportions, it features a 0.024-inch cutting diameter and a 0.036-inch length of cut, making it suited for tight-tolerance work in confined areas or shallow pockets. The micrograin carbide construction provides the rigidity and wear resistance needed for consistent performance at small diameters. With a 30-degree helix angle and right-hand spiral flutes, it promotes efficient chip evacuation while maintaining clean edge geometry. This tool is installed and run by machinists and CNC operators across job shop and production environments.

This end mill is used in CNC machining centers and manual mills where small-diameter, high-precision cutting is required. Its stub length minimizes deflection, which is critical when working at 0.024-inch diameters. The bright, uncoated finish makes it a reliable choice for non-ferrous metals, plastics, and light steel applications where coating adhesion is not a factor. The 1/8-inch shank diameter fits standard collets and end mill holders commonly found on benchtop and full-size machining equipment.

Key Features

• 0.024-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for tight dimensional control
• Micrograin solid carbide construction for hardness and edge retention at small diameters
• 30-degree right-hand helix with spiral flutes for efficient chip flow
• Stub length (0.036-inch LOC) reduces deflection in precision applications
• Center-cutting capability allows plunge entry into workpiece material
• Bright/uncoated finish suitable for non-ferrous metals, plastics, and general-purpose milling

Compatibility

Designed as an OEM-style replacement or direct-use small-diameter end mill for CNC machining centers and manual milling machines equipped with a 1/8-inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the collet or tool holder to the recommended engagement depth before tightening; insufficient engagement at small diameters increases the risk of tool pullout. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Do not exceed the manufacturer-rated speeds and feeds for the workpiece material and tool diameter.
