Titan Usa TE81326 Square End Mill 0.5in 4 Flute Cobalt

Product Description

The TITAN USA TE81326 is a 4-flute cobalt square end mill designed for aggressive material removal and precise milling in demanding shop environments. Built from M42 cobalt high-speed steel and coated with AlTiN (aluminum titanium nitride), it handles elevated cutting temperatures without losing edge integrity. The 0.5 inch cutting diameter pairs with a 30-degree helix angle and upcut flute geometry to deliver efficient chip evacuation and smooth surface finishes. This is a single-end, right-hand cut tool with a Weldon flat shank for positive tool holding. Machinists and toolroom professionals running knee mills, CNC machining centers, or manual bridgeport-style machines will find this tool at home in steel, stainless, cast iron, and high-temp alloy applications.

This end mill suits general-purpose and production milling operations in job shops, maintenance facilities, and manufacturing environments. It is sized for both manual and CNC milling machines that accept a 0.375 inch (3/8 inch) shank. The 1 inch length of cut accommodates full-depth slotting, profiling, and peripheral milling passes within standard depth-of-cut parameters. The Weldon flat shank style is compatible with standard side-lock end mill holders common across most machine tool setups.

Key Features

• M42 cobalt construction resists heat and wear in ferrous and high-temp alloy cuts
• AlTiN coating extends tool life by reducing friction and oxidation at elevated temperatures
• 30-degree helix angle promotes smooth cutting action and efficient chip flow
• Upcut flute geometry pulls chips up and away from the workpiece
• Weldon flat shank provides positive engagement in side-lock holders, reducing pullout risk
• Center-cutting design allows plunge entry into workpiece material

Compatibility

Designed for use in standard 3/8 inch end mill holders and side-lock toolholders on CNC machining centers and manual milling machines. Suitable for milling steel, stainless steel, cast iron, and similar ferrous materials consistent with M42 cobalt tooling applications.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-change procedures for the machine in use. Always power down and lock out the spindle before changing tooling. Seat the Weldon flat against the set screw in the holder to prevent axial pullout during cutting. Verify runout with a dial indicator after seating before commencing a cut.
