Eagle Cutting Tool TDD50-4024S-ALT-D 3/8 Carbide Altin End Mill

Product Description

The EAGLE CUTTING TOOL TDD50-4024S-ALT-D is a solid carbide, 4-flute, single-end end mill with a 3/8 inch cutting diameter and a 3/8 inch shank diameter. Coated with AlTiN (Aluminum Titanium Nitride), this tool delivers high heat resistance and extended tool life in demanding machining environments. Center-cut geometry allows plunge cutting in addition to peripheral milling operations. Manufactured in the USA, it is suited for machinists and tool-and-die professionals working in precision metal removal applications.

This end mill is designed for use in vertical milling machines, CNC machining centers, and manual knee mills where a reliable general-purpose or finishing end mill is required. The AlTiN coating makes it particularly effective in ferrous materials such as alloy steels, tool steels, and stainless steels, as well as harder exotic alloys. It is appropriate for both production shops and job-shop environments requiring consistent performance in tight-tolerance work.

Key Features

• 3/8 inch cutting diameter and 3/8 inch shank diameter for direct collet or end mill holder mounting
• 4-flute design provides improved surface finish and higher feed rates compared to 2-flute configurations
• AlTiN coating provides elevated heat resistance, extending tool life in dry or minimal-lubrication cutting
• Center-cut geometry enables both plunge and ramp entry without pre-drilling
• Single-end configuration maximizes rigidity for precision milling operations
• Made in the USA to solid carbide construction standards

Compatibility

Designed as a standard 3/8 inch shank end mill compatible with collet chucks, end mill holders, and tool holders accepting a 3/8 inch straight shank in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Use an appropriate collet or end mill holder torqued per the toolholder manufacturer specification to prevent pullout during cutting. Inspect the cutting edges and coating condition before each use and replace the tool if chipping or wear is observed.
