Titan Usa TC74617 Corner Radius End Mill 5/16 in 4 Flute

Product Description

The TITAN USA TC74617 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. The tool features a 5/16 inch (0.3125 inch) mill diameter, a 0.0150 inch corner radius, and a 4-flute spiral configuration with a 30-degree medium helix angle. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and hardness, extending tool life in abrasive and high-temperature cutting environments. At 4 inches overall length with a 1.625 inch reach, this is an extra-long geometry suited to deep-cavity and extended-reach applications. Single-end, right-hand cut, right-hand flute direction.

This end mill is built for machining superalloys, titanium alloys, Inconel, stainless steel, alloy steel, cast iron, and other ferrous metals. It fits straight-cylindrical toolholders with a 5/16 inch shank diameter. The extra-long length and corner radius end geometry make it well suited for profiling, contouring, and finishing passes in aerospace, mold, and general precision machining environments where a sharp corner would risk chipping or stress concentration. It handles both roughing and finishing material removal types.

Key Features

• AlTiN PVD coating for extended tool life in high-temperature and abrasive cuts
• 0.0150 inch corner radius with tolerance of -0.0010 to +0.0010 inch for consistent edge geometry
• 4-flute spiral design with 30-degree medium helix for balanced chip evacuation and surface finish
• Extra-long length (4 inches OAL, 1.625 inch reach) for deep-cavity and extended-reach operations
• Solid carbide construction for rigidity and wear resistance in ferrous and high-temperature alloy cutting
• Right-hand cut, right-hand flute, straight-cylindrical shank for standard toolholder compatibility

Compatibility

Designed for use with straight-cylindrical toolholders accepting a 5/16 inch shank diameter. Suitable for machining superalloys, titanium alloys, Inconel, stainless steel, alloy steel, and cast iron.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Secure the shank fully within the toolholder to the manufacturer-recommended gauge line before tightening. Confirm runout with a dial indicator before cutting. Always verify spindle direction, feed rate, and depth-of-cut parameters are appropriate for the workpiece material and machine capability before engaging the cut.
