Titan Usa TC74112 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The TITAN USA TC74112 is a solid carbide corner radius end mill designed for high-performance milling in demanding materials including superalloys, titanium alloys, stainless steel, cast iron, Inconel, and alloy steel. It features a 3/16-inch cutting diameter, a 0.50 mm corner radius, and four right-hand spiral flutes with a medium 30-degree helix angle. The AlTiN (aluminum titanium nitride) PVD coating improves heat resistance and tool life in ferrous and high-temperature alloy applications. This is a single-end, straight-shank tool rated for both roughing and finishing operations. Machinists and tool-and-die professionals select this end mill for precision profiling and contouring where edge strength and radius accuracy are critical.

The TC74112 is suited for CNC machining centers and manual milling operations requiring a compact-diameter end mill with reliable corner geometry. Its regular-length configuration and 5/8-inch length of cut make it practical for shallow-to-medium-depth profiling passes in aerospace, medical, and industrial component work. The straight-cylindrical shank mounts directly into standard collet chucks and toolholders. The tool excels in applications involving superalloys and titanium where heat buildup and edge wear are primary concerns.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating rated for high-temperature alloys, stainless steel, and titanium
• 0.50 mm corner radius with tolerance of -0.0010 to 0.0010 inches for consistent edge geometry
• 4-flute right-hand cut configuration supports both roughing and finishing passes
• Medium 30-degree helix angle balances chip evacuation and cutting force in superalloys
• Straight-cylindrical shank compatible with standard collet and toolholder systems

Compatibility

Designed for use with standard straight-bore collet chucks and toolholders accepting a 3/16-inch cylindrical shank. Primary workpiece materials are superalloys, titanium alloys, stainless steel, cast iron, Inconel, and alloy steel.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut, as runout beyond the corner radius tolerance will degrade edge geometry and accelerate wear.
