Titan Usa TC74122 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The TITAN USA TC74122 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. It features a 1/4 inch cutting diameter, a 0.045 inch corner radius, and four flutes with a right-hand spiral and medium helix geometry. The tool carries an AlTiN (aluminum titanium nitride) PVD coating, which supports cutting in heat-intensive applications involving superalloys, titanium, stainless steel, and ferrous metals. At 2.5 inches overall length with a 3/4 inch length of cut, it is sized for standard toolholder setups in vertical and horizontal machining centers.

This end mill is suited for both roughing and finishing operations on difficult workpiece materials including titanium alloy, Inconel, stainless steel, cast iron, and alloy steel. The 0.045 inch corner radius reduces stress concentration at the cutting edge, extending tool life in interrupted cuts and hard materials. The straight cylindrical shank at 1/4 inch diameter fits standard precision toolholders. Single-end configuration makes it a direct consumable replacement in production and job-shop environments where consistent edge geometry is required across runs.

Key Features

• 0.045 inch corner radius reduces edge chipping in hard and abrasive workpiece materials
• AlTiN PVD coating improves heat resistance and tool life in superalloys and stainless steel
• Four-flute right-hand spiral geometry supports both roughing and finishing passes
• Solid carbide construction provides rigidity and dimensional stability at elevated cutting temperatures
• Normal pitch, medium helix, and straight cylindrical shank for compatibility with standard toolholders
• Corner radius tolerance of -0.0010 to 0.0010 inches and mill diameter tolerance of -0.0020/0.0000 inches

Compatibility

Designed for use with standard precision toolholders. Primary workpiece materials include superalloys, titanium alloy, Inconel, stainless steel, cast iron, and alloy steel. Shank diameter tolerance is h6.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the toolholder is clean and free of debris before seating the shank, and torque the retention screw or collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before production cutting. Do not exceed the recommended depth of cut or feed rate for the workpiece material, as solid carbide tools are brittle under excessive lateral load.
