Titan Usa TE81306 Square End Mill 3/16 in 4 Flute Cobalt

Product Description

The TITAN USA TE81306 is a 4-flute cobalt square end mill designed for high-performance milling in demanding shop environments. Built from M42 cobalt high-speed steel and finished with an AlTiN coating, it handles elevated cutting temperatures better than standard HSS tooling. The 3/16 inch (0.1875 inch) cutting diameter and 1/2 inch length of cut make it well suited for slotting, profiling, and light shoulder milling in ferrous and hard materials. The 30-degree helix angle promotes smooth chip evacuation. This tool is installed and operated by machinists and tool-and-die professionals on manual knee mills, CNC machining centers, and benchtop mills.

This end mill fits residential and commercial machine shop applications where small-diameter precision cutting is required. The Weldon flat shank at 3/8 inch diameter seats securely in standard set-screw end mill holders and collet chucks. The upcut right-hand flute geometry pulls chips up and away from the workpiece, reducing re-cutting and heat buildup. Centercutting capability allows the tool to plunge directly into material without a pre-drilled pilot hole, adding versatility to profiling and pocket milling operations.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• AlTiN coating extends tool life in hard and abrasive materials
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting design allows direct plunge entry without a pilot hole
• Weldon flat shank at 3/8 inch diameter ensures positive grip in set-screw holders
• Right-hand cut and right-hand flute, upcut geometry for conventional milling setups

Compatibility

Designed for use in standard 3/8 inch end mill holders and collet chucks accepting a Weldon flat shank. Suitable for milling ferrous metals, stainless steel, and hard alloys in manual and CNC machining applications.

Installation Notes

Installation is performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered off before changing tooling. Seat the Weldon flat shank fully into the holder before tightening the set screw against the flat. Verify runout with a dial indicator after clamping and before commencing a cut. Follow the machine manufacturer and tooling manufacturer feed-and-speed guidelines for the material being machined.
