Titan Usa TC74446 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The TITAN USA TC74446 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials including stainless steel, superalloys, titanium alloy, Inconel, cast iron, and alloy steel. The tool features a 0.6250-inch mill diameter with a 0.0150-inch corner radius that reduces stress concentration at the cutting edge, extending tool life in aggressive applications. A 4-flute, right-hand spiral configuration with a medium helix angle supports efficient chip evacuation during both roughing and finishing passes. The AlTiN physical vapor deposition coating provides heat and oxidation resistance, making this end mill well suited to high-temperature alloy machining where surface integrity matters.

This end mill is built for CNC machining centers and vertical mills operating in job shop, aerospace, medical, and industrial manufacturing environments. It fits standard straight-cylindrical toolholders accepting a 5/8-inch shank. The long-series geometry, with a 2.2500-inch reach length and 5.0000-inch overall length, allows access to deeper pockets and features without sacrificing rigidity. Single-end construction makes it a direct-mount tool for precision contouring, slotting, and profiling operations on ferrous and high-temp alloy workpieces.

Key Features

• 0.6250-inch mill diameter with 0.0150-inch corner radius for edge strength and reduced chipping
• Solid carbide substrate for rigidity and dimensional stability in hard materials
• AlTiN PVD coating provides oxidation and heat resistance for superalloy and stainless steel applications
• 4-flute right-hand spiral with medium helix for balanced chip evacuation in roughing and finishing
• Long-series reach of 2.2500 inches enables deep pocket and feature access
• Straight-cylindrical 5/8-inch shank fits standard precision toolholders

Compatibility

Compatible with toolholders accepting a 5/8-inch straight-cylindrical shank. Suitable for material removal in superalloys, titanium alloy, Inconel, stainless steel, cast iron, alloy steel, and other ferrous metals.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank in a clean, undamaged toolholder to the recommended pull-out retention specification for the holder type in use. Verify runout with a dial indicator before commencing cuts. Confirm spindle direction is set to right-hand rotation before engaging the workpiece.
