Titan Usa TC74134 Corner Radius End Mill 5/16 in 4 Flute

Product Description

The TITAN USA TC74134 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built with a 0.3125-inch diameter, a 0.06-inch corner radius, and an AlTiN PVD coating, this tool handles both roughing and finishing operations in a single setup. The four-flute, right-hand spiral geometry with a medium helix angle promotes efficient chip evacuation and stable cutting action. At 2.5 inches overall length with a 13/16-inch length of cut, it is sized for standard toolholder mounting on CNC machining centers and manual mills.

This end mill is engineered for use on superalloys, titanium alloys, Inconel, stainless steel, alloy steel, cast iron, and ferrous metals. The AlTiN coating provides thermal resistance and hardness that are critical when cutting heat-resistant materials. It is well suited for aerospace, automotive, and general precision machining applications where tool life and dimensional accuracy matter. The single-end, straight cylindrical shank fits standard toolholders and collet chucks commonly used in production and job shop environments.

Key Features

• Solid carbide construction for rigidity and heat resistance in tough materials
• AlTiN PVD coating for extended tool life in superalloys and stainless steel
• 0.06-inch corner radius reduces stress concentration and improves edge strength
• Four-flute, right-hand spiral geometry supports both roughing and finishing
• Medium helix angle promotes smooth chip flow and reduces chatter
• Straight cylindrical shank compatible with standard toolholders and collet systems

Compatibility

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

Installation Notes

Installation is performed by a machinist or CNC operator using a compatible collet chuck or toolholder rated for the 5/16-inch shank diameter. Ensure the machine spindle is fully stopped and the tool is secured to the correct runout tolerance before beginning a cut. Verify tool projection and clamping torque per the toolholder manufacturer specifications. Do not exceed the tool's rated depth of cut or feed rate for the workpiece material being machined.
