Eagle Cutting Tool TDD50-4016S-ALT-D 4-flute Altin End Mill

Product Description

The EAGLE CUTTING TOOL TDD50-4016S-ALT-D is a solid carbide, single-end end mill designed for precision metal removal in demanding machining applications. Featuring a 4-flute geometry and an AlTiN (aluminum titanium nitride) coating, this tool delivers extended tool life and improved heat resistance during high-speed cutting operations. The 1/4 inch cutting diameter is paired with a 1/4 inch shank for direct collet or end-mill-holder mounting. Manufactured in the USA, this end mill is suited for machinists and tool-and-die professionals who require consistent performance in ferrous and hardened materials.

This end mill is well suited for milling, slotting, profiling, and contouring operations in steel, stainless steel, cast iron, and similar hard materials. The AlTiN coating reduces friction and oxidation at elevated cutting temperatures, making it appropriate for dry or minimal-lubrication machining environments. The corner-cut (C/C) geometry supports aggressive material removal while the single-end configuration is standard for most vertical and horizontal CNC machining center setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides elevated heat resistance and extended tool life
• 4-flute design balances chip evacuation with surface finish quality
• 1/4 inch cutting diameter with 1/4 inch shank for standard collet compatibility
• Single-end configuration for direct mounting in standard toolholders
• Made in the USA to consistent dimensional tolerances

Compatibility

Designed as a direct-fit replacement or standard-use end mill for CNC machining centers and manual mills accepting a 1/4 inch shank in collet chucks or end-mill holders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank to the recommended minimum insertion depth in the collet or toolholder and torque the retention nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing cutting operations.
