Titan Usa TC74441 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The TITAN USA TC74441 is a solid carbide corner radius end mill designed for demanding material removal in ferrous metals, superalloys, titanium alloys, Inconel, and stainless steel. It features a 1/2 inch mill diameter, a 0.0300 inch corner radius, and a 4-flute right-hand spiral configuration with a 30-degree medium helix angle. The AlTiN physical vapor deposition (PVD) coating provides thermal resistance and extended tool life at elevated cutting temperatures. At 4 inches overall length with a 2 inch length of cut, this end mill is sized for long-reach roughing and finishing passes in a single tool. It is installed and operated by machinists and CNC programmers in production and job-shop environments.

This end mill is suited for milling operations on superalloys, stainless steel, cast iron, alloy steel, titanium alloy, and Inconel workpieces. The corner radius end geometry reduces stress concentration at the cutting edge, extending tool life in both roughing and finishing applications. The straight-cylindrical 1/2 inch shank mounts directly into standard toolholders used on vertical and horizontal machining centers. Its long-reach configuration makes it appropriate for deep-pocket, shoulder, and contour milling where standard-length end mills cannot reach the full depth of cut.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN PVD coating rated for high-temperature cutting in superalloys, titanium, and stainless steel
• 0.0300 inch corner radius reduces edge chipping and improves surface finish at workpiece corners
• 4-flute right-hand spiral design with 30-degree medium helix for balanced chip evacuation and feed capacity
• Long-reach geometry: 2 inch length of cut, 2 inch reach length, 4 inch overall length
• Single-end, straight-cylindrical shank compatible with standard collet chucks and shrink-fit toolholders

Compatibility

Designed for use with standard toolholders accepting a 1/2 inch straight-cylindrical shank. Suitable for CNC vertical and horizontal machining centers performing roughing and finishing operations on ferrous metals, high-temperature alloys, stainless steel, alloy steel, titanium alloy, and Inconel.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the end mill. Seat the shank fully into the toolholder to the minimum insertion depth specified by the toolholder manufacturer before torquing the retention mechanism. Verify runout with a dial indicator after clamping, as excessive runout accelerates edge wear on carbide tooling.
