Titan Usa TE81217 Square End Mill 3/8 in 4 Flute Cobalt

Product Description

The TITAN USA TE81217 is a 4-flute cobalt square end mill designed for milling operations in metalworking and machining environments. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous metals, stainless steel, and other hard materials. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.375 inches in diameter with a 0.75-inch length of cut and 2.5-inch overall length, this end mill fits standard toolholders and is suited for slotting, profiling, and peripheral milling. The bright uncoated finish makes it easy to resharpen. A Weldon flat shank prevents pullout under load.

This end mill is used in CNC machining centers, manual knee mills, and bridgeport-style machines where a general-purpose cobalt end mill is required. The 3/8-inch shank diameter and 2.5-inch overall length make it appropriate for short-reach applications in medium-duty production and maintenance machining. Right-hand cut with right-hand upcut flutes and centercutting capability allow plunge entry as well as side and slot milling. It is installed and used by machinists, tool and die makers, and maintenance technicians working in job shops, production facilities, and industrial maintenance settings.

Key Features

• M42 cobalt construction for heat and wear resistance in hard material milling
• 4 flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Weldon flat shank prevents slippage in collet and end mill holders
• Bright uncoated finish facilitates easy regrinding
• Right-hand cut, right-hand upcut flute configuration for standard milling direction

Compatibility

Designed as a direct-fit replacement for standard 3/8-inch shank square end mills in toolholders and collet chucks accepting a 0.375-inch Weldon flat shank.

Installation Notes

Installation is performed by machinists using a toolholder or collet chuck rated for the 3/8-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the Weldon flat against the set screw contact point to prevent axial pullout. Verify runout with a dial indicator after mounting before engaging the workpiece.
