Accupro 14797185 Square End Mill 0.04 in 3 Flute Altin Carbide

Product Description

The ACCUPRO 14797185 is a solid carbide square end mill engineered for precision milling in demanding machining environments. With a 0.04-inch cutting diameter and three flutes in a right-hand spiral configuration, it delivers clean, accurate cuts in tight tolerances. The 30-degree helix angle promotes efficient chip evacuation, and the AlTiN (aluminum titanium nitride) coating provides heat resistance and extended tool life in ferrous and exotic alloy applications. The micrograin carbide substrate adds wear resistance at small diameters. This tool is single-end with an extended-reach design, making it suitable for deep-pocket and slotting work where reach matters.

This end mill is used in CNC machining centers and manual milling machines for fine detail work, micro-slotting, and profiling. It fits applications in aerospace, mold and die, and precision parts manufacturing where small-diameter tooling is required. The 1/8-inch shank allows direct chucking in standard collets or end mill holders. Its centercutting capability means it can plunge directly into the workpiece. The 0.325-inch reach length supports operations in recessed features or stepped part geometries.

Key Features

• 0.04-inch cutting diameter with a mill diameter tolerance of +0.0000 / -0.0010 inches for tight-tolerance work
• AlTiN coating for high-heat resistance and extended tool life in ferrous and hard alloys
• Micrograin solid carbide substrate provides rigidity and wear resistance at small diameters
• 30-degree helix angle with right-hand spiral flutes for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Extended-reach geometry with 0.325-inch reach length for deep-pocket and recessed-feature milling

Compatibility

Designed for use in standard 1/8-inch collets or end mill holders on CNC machining centers and manual knee mills; suitable for milling ferrous metals, hardened steels, and exotic alloys in applications requiring small-diameter square-end tooling.

Installation Notes

Installation is performed by machinists using a compatible collet or end mill holder sized for the 1/8-inch shank. Ensure the spindle is fully stopped and locked before loading or removing the tool. Verify runout at the cutting end after mounting, as runout errors are amplified at small diameters and will accelerate wear. Follow machine manufacturer guidelines and applicable shop safety standards for tool holding torque and RPM limits.
