Titan Usa TE81241 Square End Mill 0.75in 4 Flute Cobalt

Product Description

The TITAN USA TE81241 is a cobalt square end mill designed for precision milling in demanding metalworking and machining applications. Built from M42 cobalt high-speed steel, this tool delivers the heat resistance and edge retention needed when cutting tough alloys, stainless steels, and hardened materials. It features a 0.75 inch cutting diameter, a 1.625 inch length of cut, and a 0.5 inch Weldon flat shank that seats securely in standard end mill holders. The four-flute configuration and 30-degree helix angle balance chip evacuation with surface finish quality, making it a practical choice for both roughing and finishing passes.

This end mill is suited for use on manual knee mills and CNC machining centers in job shops, tool rooms, and production environments. It handles slotting, profiling, and peripheral milling operations in ferrous and non-ferrous workpiece materials. The bright uncoated finish and single-end, right-hand cut geometry make it a straightforward, no-frills workhorse for general-purpose milling tasks where cobalt toughness is preferred over carbide rigidity.

Key Features

• M42 cobalt construction for improved heat resistance compared to standard M2 HSS
• 30-degree helix angle balances cutting forces and surface finish quality
• Four flutes provide efficient chip clearing and smooth finish on full-slot passes
• Center-cutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Weldon flat shank prevents pullout under heavy side loads in standard end mill holders
• Bright uncoated finish compatible with a wide range of cutting fluids and materials

Compatibility

Designed as a direct-fit replacement for 3/4 inch diameter, 1/2 inch shank square end mills used in standard end mill holders and collet chucks accepting Weldon flat or straight shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Power down and lock out the spindle before seating or removing the tool from its holder. Torque the set screw against the Weldon flat to prevent axial pullout during cutting. Inspect the shank and holder bore for chips or burrs before clamping to ensure accurate runout.
