Titan Usa TE81340 Square End Mill 4 Flute Cobalt Altin

Product Description

The TITAN USA TE81340 is a 4-flute cobalt square end mill designed for general-purpose milling in ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel, it delivers increased heat and wear resistance compared to standard HSS tooling. The AlTiN coating adds a hard surface layer that extends tool life in demanding cuts. With a 0.6875-inch cutting diameter, a 1.625-inch length of cut, and a 3.75-inch overall length, this end mill suits a wide range of slot, profile, and peripheral milling operations. It is installed and run by machinists and toolroom professionals on manual mills and CNC machining centers.

This end mill is suited for shops requiring reliable performance in steel, stainless steel, cast iron, and similar materials. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during side-milling and slotting. The Weldon flat shank at 0.625 inches diameter provides a secure grip in standard set-screw tool holders. Centercutting geometry allows plunge entry, giving the operator flexibility in contouring and pocket-milling operations. It is a single-end tool intended for replacement when worn rather than resharpening.

Key Features

• M42 cobalt construction for superior heat resistance over standard M2 HSS
• AlTiN coating extends tool life in high-temperature cutting environments
• 30-degree right-hand upcut helix for efficient chip removal
• Centercutting geometry enables plunge milling and pocket entry
• Weldon flat shank at 0.625 inches for positive set-screw retention
• 4 flutes provide a good balance of chip clearance and surface finish

Compatibility

Designed as an OEM-style replacement or direct-use square end mill compatible with standard Weldon flat set-screw tool holders accepting a 0.625-inch shank diameter.

Installation Notes

Installation is performed by a machinist or toolroom technician. Always verify the spindle is fully stopped and the machine is locked out before changing tooling. Seat the Weldon flat securely against the set screw in the holder to prevent axial pullout under load. Confirm runout with a dial indicator before initiating cuts, particularly in close-tolerance applications.
