Titan Usa TC74120 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The TITAN USA TC74120 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials including stainless steel, superalloys, titanium alloy, and Inconel. It features a 1/4 inch cutting diameter, a 0.03 inch corner radius, and four flutes with a 30-degree medium helix for balanced chip evacuation and surface finish. The AlTiN physical vapor deposition (PVD) coating provides heat resistance and extended tool life in ferrous and high-temperature alloy applications. The single-end, right-hand cutting geometry is suited for both roughing and finishing operations in CNC machining environments.

This end mill is intended for use in vertical machining centers, CNC mills, and similar toolholding setups where a straight cylindrical shank is required. It performs in applications involving tight-tolerance profiling, slotting, and contouring in materials that generate high cutting temperatures. Primary workpiece materials include superalloys, titanium alloys, Inconel, stainless steel, alloy steel, and cast iron. The 3/4 inch length of cut and 2.5 inch overall length make it appropriate for standard-depth passes in precision part production.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating rated for high-temperature alloy and ferrous metal cutting
• 0.03 inch corner radius reduces stress concentration and improves edge durability
• Four-flute right-hand spiral geometry supports both roughing and finishing passes
• 30-degree medium helix balances chip flow and cutting forces
• Straight cylindrical shank compatible with standard toolholders

Compatibility

Designed for use with standard straight-bore toolholders accepting a 1/4 inch shank diameter. Suitable for CNC milling applications targeting superalloys, titanium alloys, stainless steel, alloy steel, cast iron, and Inconel workpieces.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and in a safe state. Verify toolholder runout and clamping torque per the toolholder manufacturer specifications before operation. Inspect the cutting edges and coating for damage before each use. Follow your machine tool and material manufacturer guidelines for feeds, speeds, and coolant strategy appropriate to the workpiece material.
