Widia 6144145 Square End Mill 1/8 in 3 Flute Solid Carbide

Product Description

The WIDIA 6144145 is a solid carbide square end mill designed for precision milling in metalworking applications. With a 1/8 inch cutting diameter, 5/8 inch length of cut, and a 30-degree helix angle, this three-flute tool is built for aggressive material removal while maintaining a clean square shoulder profile. The TiAlN coating extends tool life in high-temperature cutting environments. At 3 inches overall length with a straight cylindrical 1/8 inch shank, it fits standard toolholders used in CNC machining centers and manual knee mills. This tool is part of the WIDIA I3S series and is installed by machinists and tool-and-die professionals.

This end mill is suited for milling steel, stainless steel, cast iron, and non-ferrous metals in both roughing and finishing passes. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC setups. Its regular length profile fits tight workpiece geometries and standard fixturing. Centercutting capability allows it to plunge directly into the workpiece, expanding its use in slot milling, pocketing, and profiling operations across job shop and production floor environments.

Key Features

• 1/8 inch cutting diameter with 5/8 inch length of cut for precise small-feature milling
• Three helical flutes at 30 degrees for efficient chip evacuation and smooth cutting action
• TiAlN coating for enhanced heat resistance and extended tool life in ferrous materials
• Centercutting design allows direct plunge entry into workpiece material
• Straight cylindrical shank for secure clamping in standard collet and end mill holders
• Compatible with steel, stainless steel, cast iron, and non-ferrous metals

Compatibility

Designed for use with steel, stainless steel, cast iron, and non-ferrous metals as part of the WIDIA I3S series. Fits any toolholder accepting a 1/8 inch straight cylindrical shank.

Installation Notes

Installation is performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before initiating a cut, particularly at small diameters where deflection risk is higher.
