Eagle Cutting Tool TDD50-4100S-ALT-D 4 Flute Altin End Mill

Product Description

The EAGLE CUTTING TOOL TDD50-4100S-ALT-D is a single-cut, 4-flute AlTiN-coated center-cut single-end end mill manufactured in the USA. The AlTiN (Aluminum Titanium Nitride) coating provides high heat resistance and wear resistance, making this tool well suited for demanding milling operations at elevated speeds. With a 1-inch cutting diameter and a 1-inch shank, this end mill is built for rigidity and consistent performance in production and job-shop environments. It is intended for installation and use by machinists and tool-and-die professionals working with CNC or manual milling machines.

This end mill is appropriate for milling ferrous and non-ferrous metals, including steels, cast iron, and aluminum alloys, where a hard, heat-resistant coating is beneficial. The center-cut geometry allows for plunge milling in addition to standard peripheral and slot milling operations. It is a general-purpose end mill suited to both prototype and production work in machine shops, tool rooms, and manufacturing facilities.

Key Features

• AlTiN coating provides excellent hardness and thermal resistance for high-speed cutting
• 4-flute design balances chip evacuation with surface finish quality
• Center-cut geometry enables plunge entry without a pre-drilled hole
• Single-end configuration with a 1-inch shank for secure tool-holder engagement
• Made in the USA

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool compatible with standard 1-inch end mill holders, collet chucks, and hydraulic or shrink-fit tooling systems used on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding procedures for end mills. Ensure the tool holder and spindle are clean and free of debris before seating the shank. Torque set screws or collet nuts to the tool-holder manufacturer's specifications. Always verify spindle direction, feed rate, and depth-of-cut parameters against the material being machined before beginning a cut.
