Eagle Cutting Tool TDD50-4036S-ALT-D 4 Flute End Mill

Product Description

The EAGLE CUTTING TOOL TDD50-4036S-ALT-D is a 9/16 inch diameter solid carbide end mill designed for precision metal removal in demanding machining applications. It features a 4-flute geometry with a corner chamfer profile and a single-end configuration. The cutting edges are coated with AlTiN (aluminum titanium nitride), a hard physical vapor deposition coating that extends tool life at elevated cutting temperatures. This tool carries a 9/16 inch shank diameter and is manufactured in the USA to close dimensional tolerances for consistent performance in CNC and manual milling operations.

This end mill is suited for milling ferrous and hardened materials including alloy steels, tool steels, and cast iron where heat resistance and edge retention are priorities. The corner chamfer geometry makes it appropriate for applications requiring a chamfered edge profile at the base of a feature, reducing stress concentrations and eliminating sharp corners on finished workpieces. It is typically installed and operated by machinists and tooling specialists in job shop, production, and maintenance machining environments.

Key Features

• AlTiN coating provides high-temperature hardness and oxidation resistance for extended tool life in ferrous materials
• 4-flute design balances chip evacuation and surface finish in finishing and light roughing passes
• Corner chamfer cutting profile for chamfered-edge features in a single operation
• Solid carbide construction for rigidity and dimensional stability under high cutting loads
• 9/16 inch cutting diameter matched to 9/16 inch shank for direct collet or end mill holder mounting
• Single-end configuration; manufactured in the USA

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 9/16 inch straight shank end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Seat the shank fully in the collet or end mill holder to the recommended engagement depth before tightening. Verify runout with a dial indicator before commencing cuts to protect both the tool and the workpiece.
