The WIDIA 6144233 is a square end mill engineered for precision milling in metalworking applications. Built from solid carbide, this tool delivers the rigidity and wear resistance required for consistent performance in steel, stainless steel, cast iron, and non-ferrous metals. The 3-flute geometry with a 30-degree helical flute angle balances chip evacuation with cutting efficiency across a range of materials. At 0.125 inches in diameter with a 0.5-inch length of cut and 2.5-inch overall length, this is a small-diameter tool suited for tight-tolerance slot milling, profiling, and finishing work. It is installed and used by machinists and tooling professionals in CNC machining centers and manual mill setups.
This end mill is designed for use in production and job-shop environments where small-diameter, high-precision cutting is required. Primary workpiece materials include steel, stainless steel, cast iron, and non-ferrous metals. The bright uncoated finish is appropriate for applications where coating interaction with the workpiece material is a concern, or where regrinding is anticipated. The straight cylindrical shank fits standard collet and end mill holders accepting 0.125-inch shank diameters. This tool belongs to the WIDIA I3S series, which targets general-purpose solid carbide milling at tight dimensional tolerances.
Compatible with standard 0.125-inch collets, shrink-fit holders, and end mill holders used in CNC machining centers and manual milling machines. Suitable for milling steel, stainless steel, cast iron, and non-ferrous metals per material codes P, M, K, and N.
Installation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable machine safety procedures. Ensure the collet or tool holder is clean and free of debris before seating the shank to the correct insertion depth. Torque the collet nut or set screw per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as runout at small diameters significantly affects tool life and surface finish.
