Eagle Cutting Tool TDD50-4028S-ALT-D 7/16 End Mill

Product Description

The EAGLE CUTTING TOOL TDD50-4028S-ALT-D is a solid carbide square end mill designed for precision material removal in demanding machining applications. Built with a 7/16-inch cutting diameter and a matching 7/16-inch shank diameter, this tool features four flutes for improved chip evacuation and surface finish. The AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and extended tool life, making it well-suited for dry or semi-dry cutting conditions. The center-cut geometry allows for direct plunge milling as well as conventional side milling, adding versatility to the tool's application range. Machinists and CNC operators working in job shops or production environments will find this end mill built to handle repeated, high-tolerance work.

This end mill is intended for use on CNC machining centers and manual knee mills where precision profile milling, slotting, and contouring are required. The single-end configuration and solid carbide construction make it a standard choice for cutting ferrous and non-ferrous metals, including steel, stainless, aluminum, and cast iron. The AlTiN coating is particularly effective in high-temperature cutting environments where uncoated or TiN-coated tools would degrade faster. This is a USA-manufactured tool, reflecting close dimensional tolerances consistent with professional-grade cutting tools.

Key Features

• 7/16-inch cutting diameter with matching 7/16-inch shank for direct collet or end mill holder mounting
• 4-flute geometry balances chip clearance with surface finish quality
• AlTiN coating delivers heat resistance and wear reduction in high-speed cutting
• Center-cut design enables direct plunge entry without pre-drilling
• Single-end solid carbide construction for rigidity and dimensional stability
• USA manufactured for consistent tolerancing and quality control

Compatibility

Designed as a standard 7/16-inch shank end mill compatible with collet chucks, end mill holders, and milling adapters sized for 7/16-inch tooling on CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder and verify runout with a dial indicator before beginning a cut. Follow machine manufacturer guidelines and applicable shop safety protocols when securing and torquing tool holders.
