Titan Usa TC74414 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The TITAN USA TC74414 is a solid carbide corner radius end mill designed for high-performance material removal in demanding metalworking applications. It features a 0.250 inch diameter with a 0.030 inch corner radius, four spiral flutes, and an AlTiN (aluminum titanium nitride) PVD coating that extends tool life at elevated cutting temperatures. The overall length is 4.0 inches with a 1.0 inch length of cut and a straight cylindrical shank. It is built for both roughing and finishing passes and is suited for use in CNC machining centers and milling machines operated by machinists and toolroom professionals.

This end mill is engineered for cutting superalloys, titanium alloys, Inconel, stainless steel, cast iron, alloy steel, and other ferrous metals. The long-length configuration and AlTiN coating make it especially effective in high-heat environments where standard coatings degrade prematurely. Its right-hand cutting direction and right-hand flute spiral are standard for conventional milling setups. The single-end design is compatible with straight-bore toolholders and collet chucks sized for a 0.250 inch shank.

Key Features

• 0.030 inch corner radius reduces stress concentration and extends edge life at workpiece corners
• AlTiN PVD coating provides oxidation resistance for cutting superalloys, titanium, and stainless steel
• Solid carbide construction delivers rigidity and heat resistance beyond high-speed steel alternatives
• Four spiral flutes with normal pitch support both roughing and finishing material removal
• 30-degree helix angle promotes smooth chip evacuation in deep-pocket and slotting operations
• Long-length design with 1.0 inch length of cut suits extended-reach milling applications

Compatibility

Designed for use with straight-bore toolholders and collet systems accepting a 0.250 inch cylindrical shank. Primary workpiece material compatibility includes superalloys, titanium alloy, Inconel, stainless steel, cast iron, and alloy steel as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the shank is fully seated and clean before tightening to avoid runout. Confirm spindle speed and feed rate settings are appropriate for the workpiece material and depth of cut before engaging the cutter. Do not exceed the rated length of cut to avoid deflection or tool breakage.
