Titan Usa TC74443 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The TITAN USA TC74443 is a solid carbide corner radius end mill designed for demanding material removal in superalloys, stainless steel, cast iron, titanium alloy, Inconel, and alloy steel. It features a 0.5000 inch mill diameter, a 0.0600 inch corner radius, and four right-hand spiral flutes with a 30-degree medium helix angle. The AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and wear protection at elevated cutting temperatures. This long-reach single-end tool handles both roughing and finishing operations and is suited for machinists and tool-and-die professionals working in high-performance CNC milling applications.

This end mill is intended for use in CNC machining centers and manual knee mills where a straight-cylindrical shank and standard toolholder fitment are required. Its corner radius end geometry reduces stress concentration at the cutting edge, extending tool life in hard and abrasive workpiece materials. Primary applications include profiling, slotting, and contouring in superalloys and stainless steel where edge strength and coating durability are critical. The normal pitch flute spacing and right-hand cutting direction make it compatible with standard right-hand toolholder setups.

Key Features

• 0.0600 inch corner radius with tolerance of -0.0010 to 0.0010 inches for consistent edge geometry
• AlTiN PVD coating rated for high-temperature cutting in ferrous and exotic alloys
• Solid carbide construction for rigidity and vibration resistance in deep-reach applications
• 2.0000 inch length of cut and 2.0000 inch reach length on a long-length body
• Four right-hand spiral flutes at 30-degree medium helix for efficient chip evacuation
• Single-end, centercutting-capable corner radius end for profiling and finishing passes

Compatibility

Designed for use with standard straight-cylindrical shank toolholders accepting a 0.5000 inch shank diameter. Primary workpiece materials include superalloys, titanium, stainless steel, and cast iron.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the shank is fully seated and properly clamped in the toolholder before spindle engagement. Verify spindle direction is set to right-hand rotation before operation. Inspect the corner radius and cutting edges for chipping or wear before each use, particularly after cutting superalloys or titanium alloys.
