Accupro 14797192 Square End Mill 0.04 in 3 Flute Altin

Product Description

The ACCUPRO 14797192 is a solid carbide square end mill designed for precision metal removal in demanding machining applications. With a 0.04-inch cutting diameter and three flutes, this single-end tool delivers efficient chip evacuation and a fine surface finish in tight-tolerance work. The AlTiN coating resists heat and oxidation, extending tool life at higher cutting speeds. A 30-degree helix angle promotes smooth cutting action and reduces deflection. The micrograin carbide substrate provides the hardness and edge retention needed for hardened steels, stainless, and other difficult-to-machine alloys. This tool is installed and run by machinists and CNC tooling technicians in production and job-shop environments.

This end mill suits applications requiring extended reach into deep pockets, slots, or profiles where standard-length tooling cannot access. The 0.4-inch neck length and 0.4-inch reach length allow the tool to enter recessed features without interference. A 13/64-inch length of cut and a 2.5-inch overall length make it appropriate for light finishing passes and profiling operations in molds, dies, aerospace components, and precision mechanical parts. Right-hand cutting and right-hand flute direction are standard configurations compatible with conventional CNC vertical and horizontal machining centers.

Key Features

• AlTiN coating for high-heat resistance and extended tool life in ferrous and hardened materials
• Micrograin solid carbide substrate for superior hardness and edge retention
• 30-degree helix angle reduces cutting forces and improves surface finish
• Extended reach design with 0.4-inch neck length for deep-pocket and profiling work
• Centercutting geometry allows plunge entry in addition to peripheral milling
• Three-flute configuration balances chip clearance and feed rate capability

Compatibility

Designed as a standard shank end mill with a 1/8-inch shank diameter for use in collet chucks, end mill holders, and shrink-fit toolholders sized for 1/8-inch shanks on CNC machining centers and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and all motion axes at rest. Secure the 1/8-inch shank in a clean, properly sized collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the cutting edges and coating for chips or wear before each use. Runout should be verified with a dial indicator after setup to protect edge life and part tolerance.
