Titan Usa TC73984 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The TITAN USA TC73984 is a solid carbide corner radius end mill engineered for demanding material removal in superalloys, titanium alloys, stainless steel, and cast iron. It carries a 3/4-inch mill diameter, a 1/8-inch (0.1250-inch) corner radius, and four helical flutes ground to a 30-degree helix angle. The cutting edge is protected by an AlTiN (aluminum titanium nitride) PVD coating, which delivers high heat resistance and extended tool life during aggressive roughing and finishing passes. The single-end, straight-cylindrical shank seats directly in a standard toolholder for rigid, repeatable setups.

This end mill is suited for CNC machining centers and manual mills handling ferrous metals, high-temperature alloys, inconel, alloy steel, and titanium alloy workpieces. The stub-length geometry and normal pitch make it a practical choice for side milling, slotting, and profiling operations where tool stiffness matters more than extended reach. It is appropriate for both roughing and finishing applications in the same setup, reducing tool changes in production environments.

Key Features

• AlTiN PVD coating resists heat and oxidation in high-speed cuts through stainless steel and superalloys
• 0.1250-inch corner radius reduces stress concentration and extends edge life compared to square-end tools
• 4 right-hand helical flutes with 30-degree helix angle for efficient chip evacuation
• Solid carbide construction provides rigidity and wear resistance in difficult-to-machine materials
• Single-end, straight-cylindrical 3/4-inch shank fits standard toolholders with no adapter required
• Stub length type supports reduced deflection during aggressive material removal

Compatibility

Designed for use with standard toolholders accepting a 3/4-inch straight-cylindrical shank. Primary workpiece materials include superalloys, titanium alloy, inconel, stainless steel, alloy steel, and cast iron.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing the tool from the toolholder. Verify shank runout and toolholder cleanliness before tightening to ensure concentricity. Do not exceed the tool manufacturer recommended cutting parameters for the specific workpiece material, as AlTiN-coated carbide tooling is sensitive to incorrect feed and speed combinations that can cause sudden edge failure.
