Accupro 14556433 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 14556433 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 1/2-inch mill diameter, a 1-inch length of cut, and a 0.06-inch corner radius that reduces stress concentration and extends tool life in demanding cutting conditions. The AlTiN+ coating provides high heat resistance and wear protection, making this end mill well-suited for hard material applications. With 4 flutes and a right-hand spiral flute configuration, it is a single-end, centercutting tool that handles both plunge and peripheral cuts. Machinists and CNC operators install this tool in standard toolholders for ferrous and high-temperature alloy work.

This end mill is appropriate for use in CNC machining centers and manual mills across production and job shop environments. The Series 6/44 designation, micrograin carbide substrate, and AlTiN+ coating make it a strong fit for profiling, slotting, and contouring operations in hardened steels, stainless steels, and similar difficult-to-machine materials. The straight cylindrical shank fits standard 1/2-inch collets and end mill holders. It is a single-end tool intended for regular-length applications where reach extension is not required.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention in hard materials
• AlTiN+ coating for elevated heat resistance and extended tool life
• 0.06-inch corner radius reduces chipping and stress at cutting edges
• 4-flute, right-hand spiral design for efficient chip evacuation and smooth surface finish
• Centercutting geometry allows direct plunge entry without pre-drilling
• Straight cylindrical shank for compatibility with standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement corner radius end mill compatible with standard 1/2-inch end mill holders and collet systems used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down or e-stop the machine and confirm the spindle is fully at rest before changing tooling. Secure the straight cylindrical shank in a properly sized collet or end mill holder and torque the retention mechanism according to the toolholder manufacturer specification. Inspect the corner radius and cutting edges for chips or wear before each use, and verify runout with a dial indicator after installation.
