Titan Usa TE81310 Square End Mill 0.25 in 4 Flute Cobalt

Product Description

The TITAN USA TE81310 is a 4-flute cobalt square end mill designed for high-performance milling in ferrous and difficult-to-machine materials. Built from M42 cobalt high-speed steel, it carries an AlTiN coating that extends tool life under high-heat cutting conditions. The mill measures 0.25 inches in diameter with a 0.625-inch length of cut, a 0.375-inch Weldon flat shank, and an overall length of 2.4375 inches. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is intended for use by machinists and toolroom professionals on manual mills, CNC machining centers, and knee mills.

The TE81310 suits precision machining applications in job shops, production environments, and maintenance toolrooms. Its centercutting geometry allows plunge cutting as well as conventional end and peripheral milling. The right-hand cut, right-hand flute, upcut configuration is standard for general milling of steel, stainless steel, cast iron, and high-temperature alloys. The Weldon flat shank provides positive drive and minimizes pullout in high-feed operations where tool retention is critical.

Key Features

• M42 cobalt construction for heat and wear resistance in tough alloys
• AlTiN coating reduces friction and extends cutting life at elevated temperatures
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Centercutting design supports plunge entry without a pre-drilled hole
• Weldon flat shank ensures positive tool drive and anti-pullout retention
• Right-hand cut, upcut flute geometry for standard milling operations

Compatibility

Designed as a direct-fit replacement for standard 3/8-inch Weldon flat shank tool holders used with manual and CNC milling machines requiring a 1/4-inch diameter square end mill.

Installation Notes

Installation and removal should be performed with the machine fully powered down and the spindle locked. A proper Weldon flat set-screw tool holder is required to engage the flat on the shank. Inspect the holder bore and set screw threads before seating the tool. Follow shop safety procedures and applicable OSHA machine-guarding requirements when changing tooling.
