Titan Usa TC73908 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The TITAN USA TC73908 is a solid carbide corner radius end mill designed for precision milling in demanding materials including superalloys, titanium alloys, Inconel, stainless steel, alloy steel, and cast iron. It measures 1/8 inch in diameter with a 1/4 inch length of cut, a 0.03 inch corner radius, and a 1-1/2 inch overall length. The tool carries a PVD-applied AlTiN coating for heat and wear resistance at elevated cutting temperatures. With 4 helical flutes in a right-hand cutting direction and a medium helix style, it handles both roughing and finishing passes on a single tool. The straight-cylindrical shank measures 1/8 inch in diameter and fits standard toolholders.

This end mill suits CNC machining centers and manual mills where close-tolerance work on hard or heat-resistant alloys is required. It is sized for stub-length applications where rigidity and minimal deflection matter more than extended reach. Typical use cases include aerospace component work, die and mold finishing, and precision profiling in stainless steel and high-temperature alloy parts. The 0.03 inch corner radius reduces stress concentration at inside corners and extends tool life compared to a sharp-corner geometry.

Key Features

• AlTiN coating applied via PVD process for oxidation resistance and extended tool life in high-heat cuts
• Solid carbide construction provides rigidity and wear resistance in ferrous and exotic alloy materials
• 0.03 inch corner radius reduces corner chipping and stress concentration at inside radii
• 4 helical flutes with right-hand cut and normal pitch support both roughing and finishing passes
• Stub-length geometry minimizes deflection in tight-clearance or short-reach applications
• Straight-cylindrical shank with h6 shank diameter tolerance for consistent toolholder fit

Compatibility

Designed for use with standard toolholders accepting a 1/8 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 machinists or CNC setup technicians. Ensure the toolholder bore and collet are clean and free of chips before seating the shank. Confirm spindle is fully stopped and machine is in a safe state before tool changes. Follow machine tool manufacturer torque specifications for the toolholder style in use.
