Titan Usa TC73906 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The TITAN USA TC73906 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. With a 1/8 inch (0.1250 inch) mill diameter, a 0.50 mm (0.0200 inch) corner radius, and four helical flutes, it delivers both roughing and finishing capability in a single tool. The AlTiN (aluminum titanium nitride) PVD coating provides heat and oxidation resistance, making this end mill well suited for cutting superalloys, titanium alloys, stainless steel, cast iron, Inconel, and alloy steel at elevated temperatures. The straight-cylindrical shank and stub-length profile contribute to rigidity during tight-tolerance operations.

This end mill is intended for use in CNC machining centers and milling machines equipped with a compatible toolholder. Its primary workpiece materials include superalloys, titanium alloys, stainless steel, cast iron, and ferrous metals, making it a go-to choice for aerospace, medical, and precision manufacturing shops. The single-end, right-hand cutting, right-hand flute configuration is standard for conventional and climb milling setups. The stub-length design minimizes deflection, which is critical when holding tight tolerances in hard or gummy materials.

Key Features

• 0.50 mm corner radius reduces stress concentrations and extends tool life at the cutting edge
• AlTiN PVD coating provides high heat resistance for dry or minimal-lubrication cutting of superalloys and stainless steel
• Solid carbide construction delivers stiffness and wear resistance beyond high-speed steel alternatives
• Four helical flutes with normal pitch support both roughing and finishing passes
• Stub-length (1/4 inch LOC) profile minimizes deflection in short-reach applications
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use with standard straight-cylindrical bore toolholders accepting a 1/8 inch shank diameter. Suited for machining superalloys, titanium alloys, stainless steel, cast iron, Inconel, alloy steel, and other ferrous metals. Part of the TITAN USA TC series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the toolholder is properly cleaned before seating the shank. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on carbide tools. Follow your machine tool manufacturer guidelines and applicable shop safety standards when setting speeds, feeds, and depth of cut for the workpiece material.
